In raw material costs 800 million standard bricks dollars, the cost of materials for the porous masonry annual savings: 3000times; 800 元 divide; 2 = 120 million. (Note: Recipe 5% increase in cement, Branch-light brick, strength equivalent to the cost of cement and autoclave cost of sales) Therefore, Branch-light brick, relatively poor quality without the light production line investment and annual savings of raw materials fee, Branch-light brick prices would make the existing sand-lime brick production line out of the market. Brick is the use of foam cement foam of small particles and cement mixing condensed, with light, heat, noise, fire high-performance, but also because of the use of small diameter greatly reduce the cost, non-load-bearing walls of the ideal of supplies. Autoclaved foam concrete blocks are mainly made of cement, slag powder, river sand for the production of raw materials, through the pressure of the air after mixing foaming, to force air into the mix in the mixing slurry type, poured concrete structure microbubbles molded by autoclave The reaction produced by other processes, is an environmentally friendly, energy-saving materials and stable new wall materials. Use autoclaved foamed concrete building blocks as wall material, by testing for two years after completion, good quality, meet the state quality, noise, energy, fire and other standards. Also non-load-bearing walls of brick
