Description
Summary:The mechanism of the reaction taking place between NSF superplasticiser and Portland cement was examined by spectrophotometric and conductometric techniques and strength measurements using 0.1-2% admixture. The results obtained for electrolyte conductivity, kappa, mass of admixture adsorbed to cement surface, and increase in strength, provided a basis for the phenomena and effects occurring between the additive and the cement in the reaction medium. It is necessary to determine the optimum mass percent of the admixture, the type of cement, and the water/cement ratio; otherwise the positive effect of the admixture will not be obtained. 8 refs.
