Concrete block and clay brick production method
Exmork machinery manufactures concrete block making machine and clay brick making machine . Cement bricks and unfired clay cement bricks are new bricks made of clay mixed with a small amount of cement and admixtures, which do not need to be fired and are naturally cured. The production process is as follows:

Raw material selection
1. Clay: It must contain a certain amount of loose particles to facilitate mixing cement.
2. Cement: Adding 10% of 425# ordinary Portland cement can improve the strength and water resistance of the brick.
3. Admixture: Adding a small amount of admixture (reinforcement agent) can improve the hardening strength of the brick.
4. Water: The strength of the brick is high when the water content is appropriate.

Process operation
1. Mixing time: The longer the mixing time, the more evenly mixed it can be. The strength of dry mixing for 20 minutes is 15-23% higher than that of 10 minutes; the wet mixing time is preferably when the material does not clump.

2. Molding pressure: The pressure of clay cement brick during molding is best at 500 kilograms per square centimeter. Under Concrete block making machine , the product has high compressive strength and good water resistance. If the pressure is too low, it is not easy to compact.
3. Curing conditions: Clay cement bricks are generally protected by solar energy. The strength of the 7-day natural curing in the sun is equivalent to 67-90% of the strength of the 28-day age; the strength of the 28-day age is 80-95% of the strength of the quarter-year age.
