Classification of compressive strength of bricks produced by sand brick equipment:
The sand brick produced by the sand brick equipment is a dense portland concrete product, the main raw materials are lime and sand. It is made by measuring, stirring and digesting the finely ground quicklime and sand, pressurizing them and curing them under autoclave. At present, most of the bricks produced by domestic enterprises are gray sand solid bricks. Sand brick equipment can use a variety of raw materials and molds to produce different brick types, and the requirements for the compressive strength of various bricks are also different. The compressive strength of various bricks is introduced below:
1. Sintered ordinary bricks MU10, 15, 20, 25, 30;
2. Sintered hollow bricks MU2.5, 3.5, 5.0, 7.5, 10.0;
3. Autoclaved lime sand bricks MU10, 15, 20, 25;
4. Concrete solid bricks MU15, 20, 25, 30, 35, 40.
5. Ordinary concrete small hollow blocks MU3.5, 5.0, 7.5, 10.0, 15.0, 20.0
6. Autoclaved aerated concrete blocks A1.0, 2.0, 2.5, 3.5, 5.0, 7.5, 10
