提高矿渣水泥早期强度的试验研究

Enhances the Slag Cement Early Strength the Experimental Study

采用双掺法在矿渣水泥中加入适量的石灰石,可使矿渣水泥的早期强度及后期强度都略有提高.本文通过大量的对比试验,给出石灰石的最佳掺量;同时通过试样强度比值百分数的对比,分别提出掺入适量石灰石后7 d,28d抗折强度、抗压强度的提高幅度.这对克服矿渣水泥早期强度发展慢及施工期长的缺点具有一定的现实意义.

Uses double mixes the law to join the right amount limestone in the slagcement, may cause the slag cement the early strength and the long - term strength slightly has the enhancement. This article through the massive comparative trial, gave the limestone to mix the quantity best; Meanwhile through the test specimen intensity ratio percentage＇ s contrast, proposed separately after mixing in the right amount limestone, seven days, 28 day of anti - booklet intensity, the compressive strength enhance the scope. To overcomes the slag cement early strength to develop slowly, the construction period long shortcoming has certain practical significance.
