Abstract
In this research, the effects of the concrete superplastizers on the wettability of cement particle and concrete strength were studied. The wettability of the cement particles strongly depended on the type of the superplastizer. When the superplastizer had a higher wettability with the cement particles, it revealed a good fluidity of the concrete mortar and a higher concrete strength. Non-ionic superplastizers (polycarboxylic type) had a relatively good performance on the mortar fluidity and concrete strength properties compared to anionic superplastizers (lignosulfate, sulfonated naphthalene formaldehyde, sulfonated melamin formaldehyde). It was observed that the blending of the polycarboxylic and the lignosulfate type concrete superplastizers resulted in synergistic effects on the concrete mortar fluidity and concrete strength properties.
