Building stone properties Building stones are a form of construction that is used in the construction of buildings. Building stones vary; We find basalt, granite, limestone or sandstone and many others, and each type is suitable for different uses and is extracted from huge hard rocks from quarries, and these stones must be free of any cracks and be strong so that they can resist various weather factors basalt Basalt is an igneous rock, characterized by density and extreme hardness, and has many physical properties. It is characterized by a dark color, where its colors range from gray to black, and it is mainly composed of plagioclase and pyroxene minerals. In addition, its corrosion rate is low, as it contains 50% of silica, which makes it a good resistance to weathering factors due to its strong hardness . It is widely used in roads and in the construction of dams and sidewalks, as its compressive strength ranges from 200 MPa to 350 MPa. Granite Granite is widely found in nature, and its compressive strength ranges from 100 MPa to 250 MPa,as it is also considered a volcanic rock, and is characterized by its lack of pores, meaning its low ability to absorb, which makes it a weak resistance to fire, so it is widely used in Indoor stoves, and as a result of its low porosity, it is also used in floors, walls and columns due to its resistance to water penetration, and its colors range from light gray to pink sandstone Sandstone is one of the types of sedimentary rocks, and this type of stone is mixed with silica cement in the construction of heavy structures, and sandstone consists of quartz and feldspar and contains different colors such as red, brown, yellow and others. The reason for this is due to the iron oxide and silica found inside the sandstone. It is also not suitable for the construction of building facades, but it can be used in river walls, foundations and bridge walls. marble Marble is one of the very strong metamorphic rocks, where limestone is subjected to intense pressure and heat, which leads to turning it into marble. It is also characterized by its ability to be polished and cut easily and is available in white and pink TRANSLATED FROM: واجهات فلل حديثة حجر هاشمي واجهات منازل حديثة حجر هاشمي بأقل الاسعار كتالوجات حجر للواجهات الخارجية

Smart lighting Lighting or smart lighting is a lighting technology designed to save energy, as the control system performs lighting according to conditions such as occupying the place (the presence of people) or the extent of the availability of daylight. In general, the term 'smart lighting' is called the innovative lighting lamps that are manufactured from electronic circuits used for LEDS bulbs, and include the basics of the following smart lighting: #Not to rely on organic fuel to produce electricity and use alternative sources that are environmentally friendly such as solar energy. #Work to increase energy saving and maintain it by controlling operation and extinguishing. #Production of lamps of longer age control The controller easily adjusts and regulates the degree of illumination and the lamps selected to be turned on, according to the signals coming to it through the light sensors and the sensors of the presence of individuals distributed in the place. Advantages Efficiency: LEDs are more efficient than regular bulbs. For example, LEDs bulbs are used to operate a traffic light that consumes 10 watts, while the normal bulb consumes 150 watts. Therefore, the energy savings rate ranges between 82% to 93%, as about 80% of the energy in ordinary lamps is lost in the form of heat. #Operation time: LED bulbs last longer, as their operating time reaches 100,000 hours, which is equivalent to 11 years of continuous operation, while ordinary bulbs last for only 5000 hours. Adaptation: LEDs do not have an internal filament, so they are not susceptible to damage from shocks or vibrations. And the designer can assemble a number of small LEDs together to design lamps and bulbs for different uses. Diversity: LEDS bulbs offer about 16 million colors, including white. This versatility makes it extremely useful in many functions and applications. TRANSLATED FROM: مفتاح ذكي رباعي كلاسيك مفتاح ذكي مفرد كلاسيك متجر المنزل الذكي

Types of thermal cameras There are three basic types of thermal cameras, but these types differ among themselves; Because of its ability to capture different wavelengths, and the different nature of the use of each type, according to the intended purpose, and the following is a detail of these types: Short wavelength thermal cameras This type detects infrared wavelengths in the spectral range from 0.9-1.7 microns, as this range is very close to the visible light spectrum, and when using this type, the quality of the captured images is very high compared to the visible light spectrum in terms of Contrast shadows and details of the subjects being photographed. Medium wavelength thermal cameras This type detects infrared waves in the spectral range of 2-5 microns, and provides accurate images and readings, but the images are not as detailed as long-wavelength cameras, due to the increased amount of atmospheric absorption of radiation within this spectral range, usually Medium wavelength cameras are used to read extremely high temperatures such as burners and ovens. Long wavelength thermal cameras It is considered one of the most widespread thermal cameras, and it can detect infrared wavelengths within the range of 7-12 microns, and cameras operating within this spectral range provide a great deal of detail for the images that are captured, the absorption of the radiation within this range is small It provides accurate temperature measurements and can read detailed differences across low or high temperature ranges. Working principle of thermal cameras Thermal cameras detect the temperature by measuring and capturing infrared levels. All objects emit some kind of infrared radiation. After the thermal camera captures the infrared radiation emitted by an object, the processing unit analyzes these rays and converts them into an image with degrees. Cold and warm colors to indicate the different temperatures of the captured objects. uses of thermal cameras Thermal cameras are used in many different practical applications, and among these applications in brief are the following: Detecting damaged electrical wiring. Underground water leak detection. Measure the temperatures of different objects. Search for survivors in places of natural disasters.

ways to isolate buildings The methods of building insulation vary according to the nature of the building, whether it is a house, a hospital, or a company. There is thermal insulation to protect against heat in the summer and cold in winter, and moisture insulation to protect the building from mold, and sound insulation to ensure comfort in a way that prevents noise from being heard outside, and we will mention in this The article is about each type. Moisture insulation methods Humidity results from fluctuations in the climatic situation in the winter in the absence of the sun, in addition to condensation, poor drainage, and the impact of leaking ground and surface waters, and negatively affects the building, leading to a short life and the emission of fetid odors from it, not to mention the growth of insects and mice and what follows from it Viruses and diseases make the building an unhealthy home for its members. With regard to the method of insulation, the purpose of insulation must be taken into account, whether for bathrooms, basements, upper ceilings, or floors, and the nature of the land on which the building is built, whether it is sandy, dry, rocky, or wet, and the nature of the surrounding climatic condition. Is the weather mild, or rainy , or hot, and there are moisture insulating materials, including: Flexible insulating materials: contribute to preventing moisture during a period ranging from three to five years, examples of which are metal plates including lead plates, copper, aluminum, galvanized iron, stainless steel, and bitumen made from the distillation of crude oil and a variety of Between oxidized bitumen or hardened bitumen, water-proofing fluid made of a mixture of paraffin and volatile oil, and finally polyethylene tarpaulin. Semi-rigid insulating materials: such as asphalt, including asphalt chips and asphalt rolls. Rigid insulating materials: such as cement whitewash, slate boards, asbestos boards, wooden chalk boards, plastic materials, glazed tiles of Greek, Roman, Spanish and plain types, and water-insulating additives resulting from mixing hydrated lime, acid fat, iron powder, or sica, cement and medsa materials. And buckets with concrete water to stop water permeability. Thermal insulation methods Thermal insulation materials in buildings are characterized by low thermal conductivity and high heat resistance, examples of which are the following: Granules or loose fibers poured into voids, or concrete blocks. Felt or blanket and also poured into the voids of walls or ceilings, provided that it is not prone to falling. Solid panels are placed on the facade, above the ceiling, or under the moisture-insulating layer. Dielectric reflectors. concrete blocks. Insulating blinds. hollow walls. sound insulation methods Sound is transmitted by mechanical waves and pressure waves, and it depends on the number of sound waves per second and the intensity of the sound. Buildings can be isolated by absorbing these waves in one of the following ways: Use of carpets and rugs in floors. Use doors and windows made of cork, polystyrene, or rock wool. Filling the space between the walls with cement, fabric, gypsum board, or wood panels. TRANSLATED FROM: كشف تسربات المياه شرق الرياض شركة كشف تسربات المياه شمال الرياض عزل خزانات المياه بالرياض

The best way to insulate surfaces Home air conditioning, which includes heating and cooling, is necessary for the home, and the loss of that heat, whether from inside the house in winter or being inside the house in summer is undesirable, and therefore many seek to reduce the rate of heat transfer to and from the house by insulating surfaces and walls, so that walls allow For a percentage ranging between 15-20% and ceilings 10-15% of the heat to pass through them, and the following are some methods of insulating roofs of all kinds: concrete blocks or bricks They are concrete blocks used to build walls, which are based on raising the rate of thermal insulation of the house, so that they contain plastic granules or air spaces that reduce the heat transfer process outside the house, which distinguishes them from the concrete casting method is that the latter depends on pouring concrete completely to build the wall, Thus, it allows heat that is better transmitted in solid objects to transfer more easily than the method of concrete blocks only. foam boards It is an insulating foam made of polystyrene, polyisocyanate and polyurethane, surrounded by solid panels on all sides, which are installed on the walls from the outside or from the inside, so that it gives great effectiveness in thermal insulation in addition to its good heat resistance. reflective barriers Thermal reflection barriers are widely used in the summer so that they are installed on the roofs of houses or in places rich in sunlight, so that they work to reflect the sun's rays falling on that roof and keep it away, thus reducing the heat flow into the interior. Structural Insulation Panels This method is used to insulate ceilings and walls so that it depends on a prefabricated structure that consists of two facades separated by a vacuum that is filled with compressed insulating foam, and is characterized by its high efficiency to resist heat flow, and structural insulation panels can be manufactured in large sizes that require a crane to be installed on buildings. Insulation with blankets In this method, blankets are used consisting of several types of fibers such as fiberglass, plastic, natural, and also found in the form of rock wool, and are installed on floors, walls and wooden supports, and these blankets can be installed inside the faces in order to keep them away from moisture or support them in If there is wind TRANSLATED FROM: كشف تسربات المياه بالرياض شركة كشف تسربات المياه بالرياض معتمدة شركة كشف تسربات المياة بالخرج

Water leak The problem of water leakage is one of the problems that trouble individuals greatly; This is because of the damage it causes to buildings and homes, so it is necessary to strive hard to detect whether there is a water leak or not. Water leakage is defined as a defect in the water connections of various forms, whether it is in the drain pipes, elbows, or various parts of water pipes, including: faucets, tanks, and heaters. The places surrounding the leak, such as floors and walls, cause damage to them as a result of their interaction with building materials, iron corrosion and concrete wear, and thus exacerbate problems if treatment is neglected. Types of waterproofing Visible leaks: The defect that affects the prominent or existing connections on the outside of the walls and floors and is visible to the naked eye, such as faucets, external connections, heaters, or overhead tanks. This type is characterized by ease of repair and discovery. Hidden leaks: This type of leakage affects the internal connections of water, which are often inside the walls and floors, and the great difference between them and the apparent leaks is noted due to the difficulty of detecting them, as this can only be done based on the results that can be observed in the place surrounding the leak in the form of distortions and cracks Spots of changing color. Water leak detection methods There are many methods for detecting water leaks, including manual ones, and in order to be sure of that, we close all the sources that supply the house with water from valves and faucets, while giving all members of the building not to use water at all during the time period in which the sources are closed in a step to determine and monitor the meter reading and preferably continue This is the case for a period of up to five hours, and after the period has passed, the meter is read again. The issue is quickly so as not to exacerbate the problem. Ways to prevent water leaks It is usually recommended to obtain insulation services for the house, and this step is considered a method of protecting the house from all damages that may be caused to it from water and heat, so it is necessary to insulate the surfaces with water and thermal insulation against moisture, in addition to isolating bathrooms and walls, in addition to swimming pools to reduce leaks floor.

artificial marble components Artificial marble is made from a mixture of marble powder and glue, in addition to applying colors and dyes to obtain it in the desired shape, although it is man-made, but it is not judged as bad compared to natural marble, as it is widely used in many uses. Industrial marble Artificial marble is a commercial industrial alternative to natural marble, as it is manufactured by humans instead of cutting it from natural stones, as it is a type of limestone, but with a more compact texture, and a softer and smoother texture. Artificial marble is used in the manufacture of floors in addition to entrances and staircases, where there are many colors from transparent glowing to dark Advantages of using artificial marble The use of artificial marble is distinguished from natural marble by several advantages, which are summarized in: The design of artificial marble is characterized by beauty, due to the use of pigments and colors that may not be found in natural marble, which gives an ideal aesthetic, in addition to the glue used to prevent the presence of pores between the crushed marble particles, which gives an attractive shine. It is easy to maintain when exposed to minor scratches, and it is non-porous because a protective layer is placed on it, unlike natural marble, which is characterized by its porosity, which leads to it absorbing the colors of liquids if spilled on it. It is easy to clean with a soft sponge. Artificial marble is characterized by its low cost. It is easy to install without the need for additional small parts, as it is designed and manufactured based on precise measurements. natural marble Natural marble is known as a limestone composed of calcium carbonate, produced in nature by both high temperature and pressure, so it is considered a metamorphic rock, used in the manufacture of statues, monuments, table tops, interior decoration and many other uses. It consists mainly of an element Calcite, which controls the hardness of marble and its ability to reflect light and transmit depending on the percentage of calcite in the marble TRANSLATED FROM: تركيب حجر هاشمى حجر هاشمي راس ديكورات حجر هاشمي

Water leak The problem of water leakage in buildings is one of the problems facing many people and results in many damages, as large amounts of water are wasted, which economically affects the owners of the buildings. * It also increases the amount of moisture in the walls and ceilings, and this leads to damage to the building and damage to the furniture in contact with it and close to it, and it works on the emergence of fungus and mold in the house, which leads to rusting of the iron bars that are the basis of construction in any house and the weakening of its structure. Water leak detection device Moisture, wall mold and other problems that result from water leakage can be avoided by using a water leak detector. There are many different devices that detect water leakage, which differ in the way they work, and one of the best devices that is used is an electronic device that is able to detect water leakage locations through vibrations, as the water is pressurized in the pipes that may have a problem in it and the pipes near it, and the Knowing the location of the leak and crack in the pipes through the device that beeps in this place Humidity Humidity is defined as it occurs when there are large amounts of vapor in the air, and the greater the amount of vapor that the air carries, the greater the amount of moisture. Moisture has a great negative effect on buildings, as it damages furniture and wall paint, and leads to mold, and it may cause many health problems for humans, so the amount of moisture in the walls increases in the event of water leakage from the pipes that are created during construction in the walls. It is possible to get rid of the moisture that affects the walls by isolating the walls internally, or using polystyrene sheets attached to gypsum, and they are attached to the wall exposed to moisture by a type of special adhesive, as this method is economically inexpensive. There are some things that housewives can do to get rid of leaking water and the resulting moisture, and these methods include the following: Ventilate the house well, especially in the morning and open the windows on a daily basis to renew the air entering the house. The use of double glazing in windows in order to maintain high temperatures inside the house and reduce the process of water condensation on the walls. Install ventilation systems, especially in rooms without windows. Open the bathroom window after showering. Repair cracks in the walls to prevent water leakage.

Definition of limestone Limestone is a white or gray rock used in building materials and cement industries. It is a sedimentary rock consisting of calcium carbonate, which comes in the form of calcite or aragonite. This stone may contain large amounts of magnesium. Carbonate - dolomite, and includes many minor components such as clay, iron carbonate, pyrite, quartz, and feldspar. ), and have a granular texture ranging in grain size from 0.001 mm to visible particles, and these grains consist of microscopic fragments of fossil animal shells. limestone properties Most of the limestone is formed from the deposition and settlement of the skeletons of marine invertebrates. The limestone deposits are of considerable thickness, and the limestone is used as a flux for the extraction of iron, as a component of Portland cement, as a source of lime, and as a building and ornamental stone. Marl, olite, dolomite, chalk, and marble are important types of limestone. limestone sites Limestone is formed in surface, calm and warm marine waters, and this type of rock can be found between latitudes 30 degrees north and 30 degrees south of the latitude of the globe, and this stone is found in the Caribbean Sea, the Indian Ocean and the Gulf. Mexico and the Persian Gulf. This type is found in caves all over the world, and China, Russia, Japan, the United States, India, Germany, Brazil, Mexico and Italy are among the largest producers of this stone in the world, and the largest quarries that produce this stone are located in the state of Michigan in the United States. united. How is limestone formed? Limestone was formed in the water by accumulating calcium carbonate deposits with skeletons of previous life forms that died in the ocean, and mixed with other rock deposits over time. Limestone is formed by the process of evaporation, as this process occurs through the seepage of water droplets on the walls of the caves and then travels through the fractures, then this water evaporates, leaving behind calcium carbonate that forms the limestone.

clay bricks industry Clay is one of the widely spread materials, and it is inexpensive to use compared to other building materials, and builders use mud bricks to create large and stable buildings that last for many years despite the climate, and these bricks can be made by following the following method steps Determine the location or location of the soil that contains a high percentage of clay, and test it for its suitability for building bricks, and this can be done by taking a pinch of dirt and adding water to it until it becomes viscous or flexible and formable, and making a circular ball of it and placing it on a flat surface under the sun's rays Immediately and leave it for two to four days until it dries completely, and check whether it has cracks or crumbling, and if not, that means that the soil is suitable for making bricks. Gathering enough quantity to make bricks using a shovel, placing it in an open place on a flat surface and leaving it for a period of two months, during which time it is exposed to rain and sun, and it disintegrates to become sand and mud. Mixing clay sand with construction sand in the wheelbarrow, so that one quantity of construction sand for every 10 quantities of clay sand. Add water to the sand mixture so that the proportion of water is one part to four parts of the dry mixture, and knead the mixture well for three hours until it becomes a soft and formable clay. Placing the bricks in a closed room on a flat surface, then pouring clay in them to the edges, scraping the clay surface using a special tool until it becomes even, then removing the molds and leaving the bricks to dry for four weeks. Preheat the brick oven at 980°C for two hours, turn the bricks over and place them in the hot oven and leave them for 16 hours. Take the bricks out of the oven using tongs and after wearing gloves, put them on a fire-resistant surface and leave them overnight to cool down. Where is the mud? Clay can be found at construction sites and road junctions, anywhere that becomes slippery after rain and sticky when it begins to dry out. When looking for clay, it must be chosen so that it can be shaped into a pen shape that can be wrapped around the finger without breaking.
