Alkali hydroxide and alkali salt possessing high solubility are considered to be one of main reasons for efflorescence occurrence in exterior walls of buildings made from solid masonry units. Analysis of alkaline attack on efflorescence processes in the surface of exterior walls of buildings is presented herein. Volumetric changes in solid phase materials in the course of alkali hydration and carbonation reactions under efflorescence are calculated by the proposed procedure. The indicated processes are confirmed by laboratory simulation and by field studies of ceramic block and lime brick masonries, and vibropressed concrete blocks within the Republic of Bashkortostan.
