摘要
采用向普通水泥砂浆中掺入钠基膨润土的方法来对水泥砂浆进行改性,并对其凝结时间、吸水率、孔隙率和砂浆稠度等基本性能进行了研究。研究结果表明,钠基膨润土的掺入会增大砂浆孔隙率,减小吸水率和稠度,并缩短其凝结时间。
mountain sand concrete,shear compression method,compressive strength,strength curveThis paper studies the basic properties such as retarding time,water absorption,porosity and mortar consistency of the cement mortar which is modified by adding sodium bentonite into common cement mortar.The results show that the addition of sodium bentonite increases the mortar porosity,decreases water absorption,consistency and retarding time.
