Abstract
In this study, the effect of sodium bentonite on the properties of cement mortar has been investigated through a number of tests. The properties examined include consistency, fluidity, water retention, density, mechanical strength, water absorption, and morphology of mortar. The results showed that the consistency, fluidity, density, and mechanical strength decreased as the sodium bentonite increased. However, the water retention and water absorption increased because of the good water absorptive properties of sodium bentonite and the increase of voids in the mortar when the sodium bentonite increased. Scanning electron microscopy results showed that a more porous structure of mortar sample can be obtained when the sodium bentonite content increased.
