Abstract: This paper assesses durability of a high-performance concrete with large volumes of supplementary cementitious materials modified by a polyethylhydrosiloxane-based admixture and a superplasticizer. The study introduces the concept of a modified multi-component binder, comprised of portland cement, finely ground supplementary cementitious material (fly ash, ponded ash, or granulated blast furnace slag), and a highly reactive powder component (usually silica fume), modified by a superplasticizer. The observations indicated that the use of the superplasticizer and polyethylhydrosiloxane admixtures yields the required air content and air void spacing factor required for the freezing and thawing resistance. The research
confirmed that the polyethylhydrosiloxane admixture has a beneficial effect on the durability of concrete with large volumes of supplementary cementitious materials.
