Construct the dream of green building, new building clay aggregate concrete attracts attention

The history of human civilization changes includes numerous changes in building materials, and every progress embodies human wisdom.

It is precisely because of people’s complex of Qin bricks, Han tiles and tiles for thousands of years that this vast land is riddled with holes, reduced cultivated land, soil erosion, and ecological environment damage. “But save a square inch of land and leave it to your descendants to cultivate.” This is a helpless cry.

We clearly see that with the rapid development of cities, various types of construction waste are also increasing, and “garbage siege” has become an unbearable burden on the development road of many cities. In order to change this situation, during the “Twelfth Five-Year Plan” period, the state promulgated a mandatory standard for building energy efficiency to reach 65% nationwide, but very few lightweight wall materials on the market meet this indicator.

Therefore, we took the lead in starting the resource utilization of construction waste. Scientific and technological research, departmental linkage, and pilot projects first, use urban domestic sludge and river and lake sludge, construction waste, factory pulverized coal powder and other materials to obtain a low-cost, low-density, high-strength, low thermal conductivity, and corrosion-resistant material through expansion.

Strong sludge clay aggregate is used as aggregate, and the traditional chemical foaming method is improved to a physical foaming method to develop a self-insulating masonry material for green building energy saving. The block combines the advantages of clay aggregate and reinforced foam concrete, which makes it have light density, high strength, excellent heat insulation performance, small shrinkage, low water absorption and impermeability compared with general foam concrete self-insulation blocks. Strong, good frost resistance, excellent fire resistance and durability, good sound insulation and sound absorption effect, and has good shock absorption and shock resistance.

In the production process, a fully automatic frequency conversion numerical control cutting system is used to ensure the accurate size of the product, which indirectly improves the quality of the wall, so that the wall made of this kind of clay aggregate reinforced foam concrete self-insulating block has high later strength and the same service life of the building. Significant advantages. The green building using this product has huge economic and social effects, the building load is greatly reduced compared with ordinary buildings, and there is no need for internal and external wall insulation and waterproofing, reducing thermal bridges and cold bridges. Especially suitable for use in hot summer and cold winter regions.
