hollow block production in its infancy

As long as local fly ash, slag, coal gangue, sand, stone powder, slag and other industrial waste resources, which material the cheapest and most abundant use of this material brick lowest cost. Cement silo the use of technology to produce the least amount of unburned cement, higher activity material may not cement, and the production process unburned steamed, so the production cost is lower than the cost of clay brick. In addition, countries in order to promote the new wall materials, the use of clay brick building who collected 8 yuan per square meter brick funds, subsidies to new wall materials concrete batching plant hollow block production in its infancy, backward technology to people to stay Under a bad impression that can only do fences; With the scientific development and technological progress, block has been widely used in non-load-bearing walls and bearing wall construction, the use of specialized technology to produce load-bearing hollow blocks, walling material leading products, its strength is higher than clay brick strength.
