Light: porosity of 70% to 85%, the volume density is generally 500 ~ 900kg / m3, 1/5 of ordinary concrete, clay brick 1/4 1/3 hollow brick aerated concrete block, and wood almost , can float on water. Reduce the weight of buildings Hainan Jia aerated concrete block production, significantly reduce the overall cost of the building. Aerated concrete Fire: The main raw materials are mostly inorganic material, which has a good fire resistance and do not emit harmful gases in case of fire. 650 degrees Hainan Jia refractory concrete block environmental protection, as a refractory material, 90mm thick wall of fire resistance of 245 minutes, 300mm thick wall of fire resistance of 520 minutes. Impermeability: due to material made up of many separate small pores composition, the moisture absorption is slow, with volume of absorbing water to saturation is five times the time required for clay brick. For the bathroom, the walls were treated interface can be directly pasted tiles. Earthquake: the same structures, brick increase than two seismic levels. Environmental protection: manufacturing, transportation, use non-polluting, can protect arable land, energy saving Hainan Jia aerated concrete block standards, a green building materials. Durability: material strength and stability, after a year of atmospheric exposure test specimens, strength increased by 25%, remained stable after a decade. Hainan Jia sales of gas concrete block, aerated concrete blocks, the preferred Branch-building materials provided by the Shenzhen Branch-Building Material Co., Ltd. Shenzhen Branch-Building Material Co., Ltd. (www.keyujiancai.com) (www.keyujiancai.com) strong, credible, in Shenzhen, Guangdong brick, tile and brick industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Keyu building materials into the brilliant and you work for a better future!
