Action of Microaggregate in Setting and Hardening for Super Quick Setting and Super High Early Strength Cement 微集料对超速凝超早强水泥凝结硬化的作用
The results show that AS cement possesses high early strength, low hydration heat and durability, but its shrinkage rate is higher than that of portland cement. 结果表明,碱-矿渣水泥具有早强、高强、低水化热和高耐久性等优良性能,但是干缩较大;
The adoption of mixing after separate grinding process and the addition of finely ground slag with certain fineness can ensure the production of high early strength slag Portland cement with high dosage of finely ground slag. 采用分别粉磨后混合的生产工艺,用一定细度的矿渣微粉可以生产出掺量较高、早强性能好的矿渣水泥。
