| titleOfInvention | A kind of Portland fly ash cement and preparation method thereof |
| abstract | A kind of Portland fly ash cement and preparation method thereof, is made up of following raw material: cement clinker 40% ~ 52%, flyash 20% ~ 40%, slag 10% ~ 20%, gypsum 2% ~ 6%, unslaked lime 3% ~ 5%, zeolite 2% ~ 6% by weight percentage.Preparation method is: after cement clinker, flyash, slag, gypsum, lime, zeolite are sent into pulverizer pulverizing, be that 0.08mm square hole sieve tails over less than 2%, obtain Portland fly ash cement through ball mill grinding to fineness.Advantage is: technique is simple, and when increasing flyash consumption, reducing portland cement clinker consumption, ensure and improve the intensity of cement, reduce raw materials cost, flyash is fully used, minimizing flyash is to the pollution of environment. |
