Baking-free brick formula 1, fly ash brick: coal ash 30%, slag 30%, stone nitrate 30%, cement 8-10%, rock sand essence 0.2. (100kg/cm2 plus 8% cement, 150kg/cm2 plus 10% cement) baking-free brick formula 2, stone nitrate brick: stone powder 60%, stone nitrate 3%, cement 8-10%, quicklime 3%, ash powder 0.2. Formula 3 of baking-free brick, river sand brick: ① river sand 60%, stone powder 30%, cement 10-15%, mortar treasure 0.5%. ② Ash powder king 0.2%, early strength agent 0.2%, potassium chloride 0.2%. (optional) baking-free brick formula 4, shale brick (after crushing): shale 90%, cement 8-10%, rock sand 0.2, potassium chloride 0.2. 5. Gold and iron ore powder: 60% of gold and iron ore powder, 30% of stone powder, 10-15% of cement, 0.2 of rock sand essence, 0.2 of potassium chloride and 0.2 of early strength agent. 6. High content fly ash brick: 60% fly ash, 30% slag, 8-10% cement, 0.2 rock sand fine and 0.2 early strength agent. Cement brick formula: cement brick formula, unburned clay cement brick, is a new type of brick made of clay mixed with a small amount of cement and admixture, without burning, and naturally cured. The production process is as follows: 1. raw material selection 1, clay: to contain a certain amount of loose particles, in order to facilitate the mixing of cement. The clay with less sand content can be mixed with sand in the soil. Hard clay with less sand content shall be ground before sand mixing. 2. Cement: Adding 10% 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 appear cracking phenomenon. 3, admixture: the incorporation of a small amount of admixture (strengthening agent), in addition to improving the strength of the brick, but also reduce the amount of cement, reduce the cost of products. 4, water: water consumption is appropriate, the strength of the brick is high. The molding moisture is less, the strength of the brick is poor, the resistance of the material in the mold is large, the single-sided pressure is applied, and the bottom surface of the brick is not dense; The molding moisture is large, the bottom surface is wet, and it is easy to be damaged when the mold is released. When the water content of sand is 3-5%, the water consumption during molding is 10%. If the raw material fine sand is too much, it will be reduced to 8%. 2. process operation 1, mixing time: mixing time can be mixed evenly. The strength of dry mixing for 20 minutes is 15-23% higher than that of 10 minutes; the wet mixing time is appropriate for the material not to agglomerate. The storage time of the mixed material is about 2 hours. If the time is too long or too short, the compressive strength of the brick will be reduced. 2, molding pressure: clay cement brick molding pressure, 500kg per square centimeter is the best. Under this pressure, its products have high compressive strength and good water resistance. The pressure is too low to be compacted. 3. Curing conditions: clay cement bricks are generally protected by solar energy. The intensity of the 7-day age period of natural sun curing is equivalent to 67-90% of the 28-day age intensity; The 28-day age intensity is 80-95% of the age intensity of a quarter.
