| 摘 要： | 本文探讨了膨胀水泥和掺加膨胀剂的硅酸盐水泥的孔结构试验结果。分析表明,膨胀水泥石的孔结构特征不仅与水泥品种相关,而且与限制状态有很大关系。不同的膨胀水泥水化产生膨胀性晶体和填充性凝胶相不同,是造成不同水泥石孔结构特征差异的内在原因。影响膨胀水泥石孔结构特征的外在原因是限制条件,限制会明显改善膨胀水泥石的孔结构特征。

| Abstract: | Effects of expansive cements and common Portland cement with expansive agents on pore structure of cement paste were discussed in this paper.The results show that pore structure of expansive cements paste is greatly related to cement type and constrain state.The basic reason of cement paste pore structure differences is the difference of expansive crystal and filling gel phase of expansive cements.While constrain condition is external reason,it will obviously improve cement pore structure. |
