Because of the porosity of 70% to 80%, the high porosity of Ming-cheng sand self-insulating concrete products can greatly reduce the bulk density of materials. The absolute dry bulk density of different grades of products is 300-500 kg / m3, which is 1 / 4 of red brick and 1 / 5 of concrete, so it can effectively reduce the weight of buildings. Reduce the labor intensity in the construction, reduce the foundation and structure input in the building.

Although the Ming-cheng sand aerated self-insulating concrete product itself is very light, the structure of the material can be balanced in every direction of the load-bearing. One masonry brick compressive strength, equivalent to 125 clay brick compressive strength.

　　Shandong Mingcheng New Material Co., Ltd. is a company specializing in producing sand and aerated concrete self-insulation block with industrial waste as raw material. The newly developed wall material, autoclaved aerated concrete self-insulation block, has been recognized by Shandong provincial housing and construction department, and has been declared five invention patents at present. The products of B03, B04, B05 and other products have been awarded the accreditation certificates issued by the Department of housing and construction. The product has the fire protection, noise reduction, heat preservation, heat insulation and other advantages, suitable for energy-saving building construction of any standard, with "breathing" and "wet" function, light weight, high compressive strength, realize the integration of energy-saving insulation, reach energy requirements, and the construction of green building with the life of insulation materials.

　　The research and development of autothermal insulation block of autoclaved aerated concrete is the need of implementing the sustainable development strategy in China. The construction of this project is conducive to the comprehensive utilization of resources, the country. The direct utilization of ceramic tile polishing wastes reduces and inhibits the industrial waste residue to harden the surrounding land and the spread of environmental pollution. It has achieved certain social and economic benefits for saving energy, utilizing waste residue, controlling environmental pollution and improving building functions.
