摘要
研究表明:ISO标准砂7d与28d水泥胶砂强度D值回归方程线性关系显著,因此可以用ISO标准砂7dD值预测28d水泥胶砂强度D值。
The research indicated that the ISO standard sand 7d D-value is remarkable with D-Value of 28d the cement mortar＇s compression strength regression equation linearity relations, therefore may use the ISO standard sand 7d D-value to forecast D-value of 28d the cement mortar＇s compression strength.
