Abstract

Abstract The mechanism of the reaction taking place between NSF superplasticizer and Portland cement was examined with spectrophotometric and conductometric techniques, and strength measurements carried out in the presence of 0.1% – 2% of the admixture. The results obtained for electrolyte conductivity, κ, mass of admixture adsorbed to cement surface, and increase in strength, provided a basis for conclusions on the phenomena and effects occurring between the additive and the cement in the reaction medium.
