   Unburned add water content, water properly, strength bricks high. Forming less water, the difference between the strength of the brick, the material in the mold resistance is large, single-sided pressure, the bottom surface of the brick is not dense; forming more water, the bottom surface of moist, easy to damage when the mold. When the moisture content of 3-5% sand, water molding 10% is appropriate. If the raw sand too, dropped to 8%.
More than in unburned material recipe:
Fly Ash Brick: 30% ash, slag 30%, 30% nitrate stone, cement 8-10%, 0.2% fine sand rock. (100kg / cm2 plus 8% of cement, 150kg / cm2 10% cement)
