摘　　要：研究了水泥砂浆的抗压强度、抗折强度以及劈裂抗拉强度在固定硅灰掺量的条件下随着碳酸钙晶须掺量的变化关系，并以试验结果和微观形貌观察为基础探讨了碳酸钙晶须对水泥砂浆的增强增韧机理。The compressive strength, flexural strength and split tensile strength of cement mortar were determined as a function of CaCO3 whisker content under a same content of silica fume.At the same time, the reinforcing and toughening mechanism was discussed based on the experimental results and micrographs of the fracture surfaces.

关 键 词：碳酸钙晶须 硅灰 水泥砂浆 力学性能 增强增韧机理
