Кushvid A. Modifiend concretes to recover carrying capacity of special purpose structures

Dissertation is devoted theoretical and experimental compositions of concretes with enhanceable operating descriptions which are intended for renewal of bearing strength of reinforced-concrete constructions of buildings of the special setting, on the basis of establishment of conformities to the law of forming of structure of the cement matrix of concrete, modified by karboksylatnym divinel- styrol-latex and diethyleneglycol-aerosyl. There has been found out an expediency of modifying a concrete cement matrix by two polymer components - carboxylated divinyl-styrene latex and diethyleneglycol, copolymerization being a result. Modification of polyethyleneglycol-aerosyl (DEGA) by diethyleneglycol makes an aggregate dispersivity larger and increases a specific surface up to 1500 m2/kg.
