Investigations of Hydro- and Hygro-sorption Properties of Silicate Masonry Products

Abstract

The study deals with the hydro- and hygro-sorption properties in silicate masonry products of multilayer enclosurestructure, such as sorption moisture content, capillary water adsorption, water vapour permeability, water absorption andimpact of the impregnation of aplite face brick surface by hydrophobic liquid SILRES BS16 on its frost resistance. Itwas established that moisture content in silicate products may vary from 1.65 % to 12.0 % subject to operationconditions. The investigations showed that upon determination of frost resistance no visible injuries were observed onthe wall surface after 50 cycles of freezing.
