Characteristics of cement brick How to choose cement brick?

Cement bricks are light in weight and high in strength, and do not need to be fired. The use of power plant pollutant fly ash is environmentally friendly and has been widely promoted in China. The rare disadvantage of this kind of block is that it is not as good as red brick when combined with plastering mortar, which is easy to cause cracks in the wall and affect the appearance. Water should be sprayed fully during construction, and steel wire mesh can be hung on the walls of villas with high requirements, which can effectively prevent cracks.

1. Weighing: Weigh, the relative quality will be slightly better.

2. Falling: Look at the material when falling, and see if the material is evenly distributed and the density is high. Too little aggregate can't be broken, and the strength is not high.

3. Look: Look at the surface. First, look at beautiful colors (beautiful colors cost more. ), and then look at the strength of the surface layer (you can use keys or steel nails. The strength of the easy-to-fall surface layer is low)

4. Listen: Knock on the brick and listen to the sound. High acoustic brittle strength and uniform cementation. But too brittle is not good, too much cement, too brittle, easy to break, no toughness.
