Analysis of the Influence of Microcalcite on the Efficiency of Joint Work of Filled Polymer Coatings with Concrete Bases

The paper presents the study results of the joint work of microcalcite-filled polymer coatings with concrete bases. The analysis of change of bending strength and maximum deflection of concrete samples with the filled polymer coating based on epoxy resins depending on the degree of filling and the fractional composition of microtremor was carried out with the use of contour lines and three-component diagrams of Rozebom-Gibbs. The study revealed the compositions of polymer coatings that provide the greatest increase in strength characteristics even when using high-filled mixtures with a minimum consumption of the binder.
