Study of the Impact of Microstructure and Sorption Properties of the Renovation Plasters on the Wall Drying Rate

Abstract

The purpose of the study was to determine the relationship between the microstructure and sorption properties of plasters and the drying rate of walls made of sandstone, silicate bricks, ceramic Gothic and Cadinen bricks. The porosity of plasters was 30%, 40% and 50%, and they differed in water sorption. The studies were carried out with one and two layers of plaster. It was demonstrated that the properties of the renovation plasters influence their drying rate. Plasters with a polymodal distribution of pore size and porosity of 50% shortened the wall drying rate, while monomodal distribution and hydrophobic plasters extended the wall drying rate.
