Deformative properties of high strength fine-grained concretes with organic-mineral modifier on the basis of mineral wastes of Donbas industry
Abstract: The technology of high durability concretes and concretes with ligh explotative propertives is connected with using in their composition indissolubly of organic-mineral modifiers on the basis of dispersed pozzolanic addition and effective superplasticizers of new generation. The composition of combined organic-mineral modifier, including condensed microsilica and thermo power station slag, jointly grinded in the presence of SNF superplasticizer has been eleborated. This modifier allows to get hi-tech fine-grained concrete mixtures and concretes of high durability (B 100) with improved deformative properties. The efficiency of the organic-mineral modifier in a high durability fine-grained concrete can be essentially increased when concrete mixture preparation is separate and when the second superplasticizer FM-794 with the steric mechanism of concrete mixtures stabilizing (modified polycarboxylic ether) is used.
Keywords: fine-grained high durability concretes, organic-mineral modifier, microsilica, thermo power station slag, superplasticizer, prism strength, deformative properties.
