In the paper results of structure formation of Self-Compacting Concrete (SCC) mixtures based on superplasticized cementitious systems and properties of hardened SCC are shown. During the hydration process in the superplasticized cementitious systems “Portland cement clinker - gypsum - mineral additives - limestone microfiller - polycarboxylates - alkali-metal salts” there is a reaction in the unclinker part with formation of ettringite by a topo-chemical reaction, which provides the compaction of cement matrix of SCC. The SCC on the basis superplasticized cementitious systems are characterized by such properties as high strength, corrosion resistance, frost resistance, low porosity, high reliability and durability of constructions in different conditions.
