摘　　要：研究了相同流动度下,不同含泥量对水泥胶砂强度的影响。结果表明,水泥胶砂中含泥量的增加容易引起拌合用水量的增大和水泥胶砂抗折强度的降低。含泥量对水泥胶砂抗折强度的影响大于对抗压强度的影响,水泥胶砂的抗折强度对含泥量的变化更加敏感。The effect of various mud contents on the strength of cement mortar with the same flowability was investigated. Theresults indicated that the increase of mud content in cement mortar could easily result in the increase of mixing water and thedecrease of flexural strength of mortar, and mud content had a greater influence on the flexural strength than on the compressivestrength, which means the flexural strength was more sensitive to the change of mud content.

关 键 词：含泥量 水泥胶砂 相同流动度 抗压强度 抗折强度
