Abstract
In this paper, the role of tricalcium aluminate (C3A) and gypsum dehydration level in the air-entraining mechanism in concrete was studied. A higher-performance air system was achieved when anionic surfactant was used, C3A content was higher and gypsum dehydration didn’t occur. Adsorption on cement particles dominates the air-entraining mechanism when anionic admixture is used. Anionic surfactant performs higher quality air microstructure than cationic, despite much lower surface tension reduction. Thus, the adsorption of admixture had a major role in the effective air-entraining mechanism process. This effect has significant implications on the selection of the best-suited surfactants, cement optimum composition and the cement production procedure for the highest frost resistance concretes used for roads and bridges.
