摘要

The influence of slag or limestone as a cement main constituent on the performance of superplasticizers based on polycarboxylate ether (PCE) was investigated on cements made of identical clinker and sulfate components. Investigations were done by means of pore solution analyses, zeta potential measurements and consistence tests. Depending on the proportion of clinker in the cement the composition of the pore solution, the zeta potential of cement paste and the effective charge of PCE varied significantly. This led to a modified adsorption behavior and plasticizing effect of PCE. Consequently, the specific plasticizing effect of PCE can be diminished with decreasing proportion of clinker in cement.
