Embodiment 1
[0032] Crushing and grinding the dolomite, drying the original phosphogypsum and phosphorus slag through a drum dryer until the free water content is less than 3%; weigh 55 parts of dolomite, 2 parts of phosphogypsum, and 2 parts of phosphorus slag in parts by weight. 1 part, 14 parts of fly ash, 25 parts of limestone, 1 part of strontium oxide, and 1 part of sodium tungsten, mix them evenly to get raw meal; place the raw meal in a rotary kiln for calcination at 1250°C for 60 minutes, and then quench the temperature with a grate cooler , lowered to below 400°C within 30 minutes, and finally ground by a ball mill to 80 μm sieve ≤ 10%, that is, the finished multi-component composite reinforced anti-cracking agent for concrete is obtained.
Embodiment 2
[0034] Crushing and grinding the dolomite, drying the original phosphogypsum and phosphorus slag through a drum dryer until the free water content is less than 3%; weigh 73 parts of dolomite, 3 parts of phosphogypsum, and 1 12 parts of fly ash, 10 parts of limestone, 1 part of molybdenum oxide, and 1 part of calcium fluoride, and mix them evenly to obtain raw meal; place the raw meal in a rotary kiln for calcination at 1300°C for 60 minutes, and then cool it rapidly with a grate cooler , lowered to below 400°C within 30 minutes, and finally ground by a ball mill to 80 μm sieve ≤ 10%, that is, the finished multi-component composite reinforced anti-cracking agent for concrete is obtained.
Embodiment 3
[0036]Crushing and grinding the dolomite, drying the original phosphogypsum and phosphorus slag through a drum dryer until the free water content is less than 3%; weigh 80 parts of dolomite, 3 parts of phosphogypsum, and 1 1 part, 11 parts of fly ash, 3 parts of limestone, 1 part of molybdenum oxide, 0.5 part of sodium tungstate, and 0.5 part of zinc oxide, and mix them evenly to obtain raw meal; place the raw meal in a rotary kiln for 90 minutes at 1300 °C, and then The grate cooler is used for rapid cooling, and the temperature is lowered to below 400°C within 30 minutes. Finally, it is ground by a ball mill until the sieve residue of 80 μm is ≤10%, and the multi-component composite reinforced anti-cracking agent for concrete is obtained.
