The technology of mortar injection into a concrete element of construction is developed in the paper. The different methods of applying the repair polymeric mortar on the base of alkylrezorcine on concrete surface of a construction, which are used depending on damage rate of the construction and provides high level of adhesion to concrete, are presented.
The comparison of classical and computer testing system is given in the article. The effect of usage of «Prometey» remote education system is analyzed. The positive effects of passing the Module Tests by students are shown.
In the article the analysis of polymer-cement mortars for their application in construction and repair of buildings and structures is presented. The main properties of known polymer-cement mortars used for this purpose are described. The advantages of application of polymer-cement mortars as repair materials are shown.
In the article are brought studies a physicist-mechanical characteristics an dissolves for concreting under water. On results of studies movable and toughness features is designed optimum compositions for filling under pressure at the concrete transport erecting repair under water.
In the article the detailed analysis of advanced production technologies and modification methods of light concretes on inorganic astringents and fillers is presented. The basic ways of optimization and improvement of production technologies of the light concretes are determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
