Cement bricks can be seen everywhere in our daily life. Most of the open space in the community is paved with it. The open space in front of the supermarket will also be paved with cement bricks. Cement bricks are a cheap, durable and convenient new wall material. Because it is more environmentally friendly, the country is now vigorously promoting it. Of course, cement floor tiles are cement bricks of different colors. It is not enough to repair the wall or install them on the floor. Today we will show you the cement floor tiles. Production methods and materials and recipes.

1. Cement floor block formula

1. Clay: It must contain a certain amount of loose particles to facilitate cement mixing. Clay with less sand content can be mixed with sand in the soil. Clay with little sand content and relatively hard should be ground before adding sand.

2. Cement: Adding 10% of 425# ordinary Portland cement can improve the strength and water resistance of the brick, and it will not crack after soaking in water. Otherwise, the general brick will crack.

3. Admixture: A small amount of admixture (reinforcing agent) is added, which can not only increase the induration strength of the brick, but also reduce the amount of cement and reduce the cost of the product.

4. Water: If the amount of water is appropriate, the strength of the brick will be high. If there is less moisture in the molding process, the strength of the brick will be poor, and the resistance of the material in the mold will be large. If one side is pressed, the bottom of the brick will not be dense; When the moisture content of the sand is 3-5%, the appropriate water consumption for molding is 10%. If the raw material fine sand is too much, it will be reduced to 8%.
