摘要
界面是混凝土强度的薄弱环节，尤其是粗骨料与水泥石的界面对混凝土强度的影响至关重要．改善界面粘结能明显地提高混凝土的强度．本文通过掺水玻璃使界面区的晶体Ｃａ（ＯＨ）２转变为凝胶，从而有效地改善了界面粘结并提高了混凝土的强度．
interface is the weaker link of concrete strength, especially the interface between the coarse aggregate and cement paste is the most important affecting factor for concrete strength. Improving the interface coherence tan obviously enhance the strength of concrete. In this paper through adding water glass, the interface crystal Ca(OH)2 has been changed into gel, so that the interface coherence has been improved and the concrete strength also has been enhanced.
