(1) Cement: the incorporation of 10% of 425 # ordinary portland cement, can improve the strength and water resistance of bricks, cracking after immersion in water. Otherwise, there will be general brick cracking phenomenon. 2, additives: the incorporation of a small amount of additives (booster), in addition to improving strength brick induration, but also reduce the amount of cement, reduce product costs. 3. Water: water appropriate, Wuhan cement tile, brick intensity will be high. Forming less water, the difference between the strength of brick, the material in the mold resistance, single-sided pressure is not dense brick bottom surface; forming more water, the bottom surface of moist, Wuhan cement prices, when the mold is easy to break something. When the sand moisture content of 3-5%, water consumption by 10% during molding is appropriate. If the raw material sand too, is reduced to 8%.
