production Shenyang gas filling block The main raw materials are cement, lime, sand, fly ash, etc.

Production Aerator block Bricks are cement concrete products, which contain calcium silicate hydrate colloid generated by water maintenance. The water cement ratio is large, the binder is more, and the aggregate is air. Although autoclaved, the reduction value can only be controlled within 0.04% (4/10000)~0.06% (6/10000) according to cost factors, which is larger than traditional sintered clay bricks. Specifically:

1. Fly ash: it shall conform to JC/T409-92, and the skill requirements are as follows: radioactive substances shall conform to GB9196-88. The content of SIO2 and AL2O3 is more than 78%, the loss on ignition is less than 8%, and the residue on 0.08mm sieve is less than 15%;

2. Lump quicklime: it should conform to the provisions of JC/T621-1996. The skill requirements are as follows: A-CaO content is more than 65%, digestion time is 8-15min, digestion temperature is more than 65 degrees, over burnt lime content is less than 8%, fly ash content is less than 11%, and MgO content is less than 5%;

3. Gypsum: skill requirements are as follows: hydrogypsum or phosphogypsum, with SO3 greater than 35%;

4. Aluminum powder or aluminum powder paste: the solid content is more than 65%, and the active aluminum content is more than 65%;

5. Cement: It shall conform to the provisions of GB175-92, 32.4R bulk cement.
