Abstract

The paper presents the measured data on interfacial tension of bentonite suspensions and strength of a cement stone in water solutions of Frem Giper S-TB superplasticizer. The interfacial tension of water-surfactant-bentonite suspension is experimentally measured at various concentrations of a bentonite solid phase. The dependence of interfacial tension on the concentration of a solid phase is quite complex. In particular, the minimum is observed on interfacial tension isotherms at 3 wt.% of bentonite. Isoplastic cement mixes are obtained from the above suspensions. The cement stone samples are made of these mixes. The strength test of these samples showed a considerable increase of the compression strength. At the same time, 3 wt.% of bentonite demonstrated the maximum increase in strength.
