摘要：

The effects of superplasticizing admixtures upon rheological properties of cement mixes have been investigated. Their effects upon the zeta potential generated at the interface between cement particle surfaces and the admixture-containing liquid were studied by electrophoretic and streaming potential techniques. Comparisons were made between the above results and the results of mortar flow measurements; the results of rotational viscometric measurements on slurries also revealed a strong influence of the admixtures upon the apparent viscosity. Significant correlations are made among the results of zeta potential, flow properties and adsorption isotherm measurements. © 1979.
