Substitute for solid clay brick

The production of red bricks has always been in accordance with the production process of digging-making mud-firing. A red brick needs several times its volume of raw materials, and it needs a lot of soil when it is made, which will inevitably occupy a lot of cultivated land.

The concept of aerated concrete brick Aerated concrete is a light porous silicate product made of siliceous materials (sand, fly ash and siliceous tailings, etc.). ) and calcareous materials (lime, cement) as the main raw materials, with gas-generating agent (aluminum powder), through batching, stirring, pouring, pre-curing, cutting, autoclaving, curing and other technological processes. Aerated concrete is named after it contains a large number of uniform and fine pores after inflation.

Autoclaved foamed concrete brick Autoclaved foamed concrete brick: Foam is prepared by using foaming agent through machinery, and high-quality foam which is not easy to rupture is forcibly added into the mixture of cement-based cementing material, aggregate, admixture, additive and water to form light thermal insulation slurry with a large number of closed pores, and then it is poured and autoclaved to form microporous silicate products. Physical foaming and autoclaved curing are two main characteristics of autoclaved foamed concrete bricks.

air brick

The common manufacturing raw materials of hollow brick are clay and cinder ash, which are light in weight and high in strength, which can save a lot of clay and reduce the weight of the wall. The holes in hollow brick have sound insulation function.

So no matter from that point of view, the advantages of hollow bricks are great. In order to protect cultivated land and human living conditions, it is best to use hollow bricks. ?
