DRY CONSTRUCTION MIXTURES FOR POUR FLOORS BASED ON REACTIVE POWDER CONCRETE

Abstract

This article presents the results of experimental studies of building mixtures for the installation of self-leveling floors based on reaction-powder concrete. Reaction-powder concretes (RPC), in turn, before mixing with water, can be considered as a dry mixture containing a binder, a dispersed filler, a superplasticizer, and, if necessary, modifier additives. RPB provide high strength, adhesive ability and durability of concretes and mortars in different operating conditions. By adjusting the composition of the RPB with different components, it is possible to achieve the properties of dry mixes, mortars and concretes for various purposes. Dry building mixes are promising types of building materials and are increasingly used in the construction industry and are becoming more relevant in construction due to a number of advantages compared to commercial solutions. The use of dry building mixes contributes to an increase in labor productivity and quality of work, a reduction in transportation and storage costs, and a reduction in technological operations. The article shows the possibility of obtaining such mixtures, and also presents and analyzes experimental and statistical models of technological and physical-mechanical properties of mortar mixtures and self-leveling floors, shows ways to improve them.
