Sand aerated block It is a stone that can float on the water some people call it pumice! The air hole in the middle makes this material very light - also called light brick, foam brick, light partition brick; It also enables this material to block sound - also known as sound insulation brick, sound insulation brick; Because the material contains a lot of air - also called aerated brick Aerator block ; At the same time, this material has good thermal insulation and fire prevention performance - also known as thermal insulation brick, thermal insulation brick, fireproof brick, energy-saving brick; Most importantly, it is made of concrete and has high strength.
Functional features
1. Light weight and high strength: the absolute dry unit weight is 500-700kg/m3, which is 1/4 of the standard brick and 1/3 of the clay brick. Therefore, it can effectively reduce the dead weight of buildings, reduce the investment in foundation and structure, and is very suitable for frame structures in various industrial and civil buildings, as well as buildings in weak geology.
2 Thermal insulation: the thermal insulation performance is 7 times that of clay brick, 10 times that of ordinary concrete, and 3-4 times that of clay solid brick, and the thermal conductivity is usually 0.09-0.17w/(m.k). Using 20cm thick products as external walls, its thermal insulation effect is equivalent to that of 49cm solid brick walls. It is warm in winter and cool in summer, greatly improving living conditions, saving energy, and increasing the use area of buildings.
3. Impermeability and waterproof: the internal holes of the product are all independent closed holes, with a diameter of about 1-2mm, which can effectively prevent moisture diffusion. If special adhesive is used for masonry, the product mortar joint is 3/4mm, which further improves the overall impermeability of the wall.
4 Fire prevention and flame retardancy: the raw materials and products of this product are inorganic, which are absolutely incombustible, and will not lose strength under 700 ℃ high temperature, and will not produce toxic gas in case of fire. The wall with a thickness of 10 cm can prevent fire for more than 4 hours, which is an ideal first class fireproof building material.
5 Sound insulation and absorption: It has good sound insulation effect, which can be 40-50 dB depending on its thickness. It is also a good sound absorption material.
6 Size accuracy: the length, width and height of the product are within the range of 2-3mm, meeting the requirements of national standards, making it possible to promote the application of thin layer mortar.
7 Green environmental protection: It is a green environmental protection product and can meet the strict European environmental protection requirements.
8 Convenient construction: continuous masonry can be used to greatly improve labor efficiency. Good field processing performance, sawing, planing and size trimming. When installing water and electricity facilities, drilling, grooving and opening are convenient and fast. Air conditioners, water heaters and other heavy objects shall be installed reliably.
9 Economical and practical: the cost of foundation and structure treatment can be greatly reduced due to the reduction of building weight. Because of its precision, the surface can be directly embedded in batches, reducing the materials and labor required for surface painting; Because the thickness of the product is relatively small, it can improve the building utilization coefficient and increase the use area.
