Abstract

Influence of Bentonite on Mortar Performance and Its MechanismFAN Yi-tang(Zhejiang Huanyu Constraction Group,Shaoxing 312000,China)Modified effect was studied on fresh mortar and hardens mortar with bentonite.The test indicated that the water retention and workability of fresh mortar with bentonite was improved,and the apparent density of fresh mortar was depressed by bentonite.With the increase of bentonite mass,the compressive strength and creasing strength slightly depressed.The mechanism of water retention and thixotropy of fresh mortar with bentonite was studied.bentonite;mortar;water retention admixture;mortar admixture;thickening agent
