Effective polymer concrete on waste concrete production

Abstract

Finish materials in facade systems are experiencing significant stress associated with atmospheric and mechanical influences. The use of tiles with high durability and the ability to relax deformations will allow to obtain efficient cladding for building systems. The article presents the results of the selection of compositions and technologies of a composite material based on finely ground highly active waste produced by portland cement, mineral binder, additives based on polycarboxylic ether MC-6955, and polymer additive MC-Adhesive. MC-Adhesive is a polymer additive used for: a significant increase in flexural strength; reduce the elastic modulus; increase water resistance; increase the concrete mix cohesion; making coatings with high requirements for abrasion, low dusting and high resistance to aggressive substances.The article presents the results of research methods of selection of compositions of composite polymer concrete. The strength characteristics of polymer concrete with an average density of 2370-2450 kg/m3 are most dependent on the consumption of fine waste and polymer additives. The nomogram obtained as a result of an active experiment makes it possible to evaluate the dependence of the strength on these factors and select their optimal ratio.
