In raw material costs 800 million standard bricks dollars, cost of materials lightweight brick equipment, the annual savings for the porous masonry: 3000times; 800 元 divide; 2 = 120 million. (Note: Recipe 5% increase in cement, strength equivalent to the cost of cement and autoclave cost of sales) Therefore, no comparative poor quality light production line investment and annual savings of raw material costs, light brick, is enough to make the existing sand-lime brick production lines out of the market. Construction of: light brick has good processability, convenient and simple construction, light brick material, due to the large block, light weight, can reduce labor intensity, light brick picture, improve construction efficiency, shorten the construction period. Refractory: refractoriness of 700 degrees, as a refractory material, 100mm thick brick fire resistance of 225 minutes, 200mm thick brick fire resistance of 480 minutes.
