The relationship between the late-age hydration and strength development of cement-slag mortars have been investigated by measuring the compressive strengths and the non-evaporable water contents. The results show that the late-age strength increases with increasing the slag content. Increasing the fineness of slag makes greater contribution to the late-age strength improvement at high water to binder ratio than that at low water to binder ratio. At lower water to binder ratio, the increasing rates of compressive strength and non-evaporable water content are smaller. There is a linear relationship between the increasing rate of compressive strength and the increasing rate of non-evaporable water contents. The slope is almost the same for all the samples at constant water to binder ratio and decreases with decreasing the water to binder ratio.

水泥渣砂浆的后期水化与强度发展的关系

通过测量抗压强度和非蒸发水含量，研究了水泥渣砂浆的后期水化与强度发展之间的关系。结果表明，随着炉渣含量的增加，时效强度增加。与低水胶比的情况相比，提高炉渣的细度对高时效强度的提高贡献更大。在较低的水与粘合剂比率下，抗压强度和不可蒸发的水含量的增加速率较小。抗压强度的增加速率与不可蒸发水含量的增加速率之间存在线性关系。在恒定的水与粘结剂比率下，所有样品的斜率几乎相同，并且随着水与粘结剂比率的降低而减小。
