Influence of the type of plaster finishing on the thermal properties of brick building components

A research of the thermal properties of two fragments of masonry made of full-bodied brick in the climatic chamber was carried out. The difference in the tested fragments is due to the difference in ex-ternal plaster coatings: cement and lime. The temperatures and heat fluxes measured at three modes of testing were measured. The results demonstrated that the thermal resistance of a fragment with lime plaster turned out to be more than that of a fragment with cement plaster. In addition, after completion of the test cycle, numerous hair cracks were revealed on the masonry fragment plastered outside with ce-ment plaster, the appearance of which is due to cyclic temperature and humidity deformations
