RESEARCH OF OPERATIONAL PROPERTIES OF HIGH STRENGH LIGHTWEIGHT CONCRETE MODIFIED BY INTEGRATED ORGANIC AND SILICEOUS ADDITIVES

Abstract

The article has the compound of high-lightweight concrete and research results of operational properties of lightweight concrete based on portland cement modified by a complex of organic-silica additives based polycarboxylates superplasticizers different brands and finely ground tripoli. It is established that the use of such additives contributes not only for increase strength of concrete, but decrease deformation of shrinkage, increase corrosion resistance, frost resistance, waterproof of lightweight concrete by reducing the open porosity and directed the formation of the phase composition of products hydration compared in comparison with the samples of concrete without additives.
