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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
