Improving Performance Characteristics of Reinforced Concrete Structures Using High-Elasticity Pigments for Surface Coating
Abstract
This article presents the experimental research carried out into the efficient surface coatings made of high-elasticity pigments for concrete structures exposed to the deformation due to cracking. In contrast to application fields claimed by the manufacturer, high-elasticity (rubber) pigments can be used in such applications as coloring the exposed surfaces of bearing frame element of a building, i.e. reinforced concrete crossbar; outer layer of the three-layer concrete wall panel. Tests are conducted for the three-layer wall panel coated with a high-elasticity pigment to determine the vapor permeability of the outer layer of the structure. The rationale is shown for a possible use of the high-elasticity pigment both without disturbing the thermal efficiency of the structure and room microclimate. New information is obtained allowing to increase the operational reliability of the considered structures without significant and expensive structural modifications.
