Accelerated Test Method of 48 Hours to Predict Cement 28d Compressive Strength

48h预测水泥28d抗压强度新方法的前期研究表明对硅酸盐水泥、普通硅酸盐水泥和复合水泥预测强度准确性高,采用新方法对6大通用硅酸盐水泥中的其他品种水泥进行强度预测。研究结果表明,使用该方法能够准确预测粉煤灰硅酸盐水泥、矿渣硅酸盐水泥和火山灰质硅酸盐水泥28d强度,预测值/实测值的均值为0.97。

The prophase studied show that accelerated test method of 48 hours accurately predicted the 28-day cement strength of P·I,P·O and P·C. This paper uses the new method to predict the strength of other varieties of cement in the 6 common portland cement. The results of the study show that,using this method can accurately predict the 28-day cement strength of P·F,P·S·A and P·P,in which the mean of（ predicted value /measured strength） is 0. 97.
