Concrete blocks refer to the use of fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. (one or several of the above raw materials) as the main raw material, using cement as a coagulant, without high temperature calcination A new type of wall material manufactured is called cement brick.
Cement bricks used to produce by block making machine are lighter in weight, higher in strength, and do not need to be fired. The use of pollutants from power plant fly ash is relatively environmentally friendly, and the country has already vigorously promoted it. The only shortcoming of this kind of block is that it is not as good as the red brick in combination with the plaster, which is easy to crack on the wall and affect the appearance. Water should be sprayed fully during construction. For high-grade villas, consider a wall-mounted steel wire mesh to prevent cracks.
The most common cement bricks on the market are 240*115*53mm standard bricks, referred to as standard bricks; 240*115*90mm eight-hole blocks; 390*190*190mm hollow blocks and other specifications.
Cement brick standard (taking 240×115×90mm for wall brick as an example, strength grade 10MPA) Material: ordinary concrete or high permeability fly ash concrete
