Abstract
The influence of a type of new generation: superplasticizer (SP), air-entraining admixture (AEA), viscosity modifying admixture (VMA) and anti-foaming admixture (AFA) on the air-content, workability of high performance self-compacting concrete (HPSCC), is analyzed in the paper. The purpose of this study was to examine the influence of the type of admixtures on porosity and pore size distribution of HPSCC at constant water on cement ratio, type and volume of aggregate and volume of cement paste. The parameters of the air-voids of hardened HPSCC are also investigated. The results presented in the article demonstrated that admixtures from different sources cannot be used interchangeably, even if they appear to have a similar chemical composition.
