METHOD OF REDUCING INTENSITY OF SALT EFFLORESCENCE FORMATION ON SURFACE OF CEMENT MORTAR MASONRY

摘要

FIELD: construction. ^ SUBSTANCE: method of reducing the intensity of salt efflorescence formation on the surface of cement mortar masonry presupposes preparation of a portland cement based mortar with addition of a bicomponent mineral admixture in amount of 30-40% of the portland cement total weight, the admixture composition being as follows (% of the portland cement total weight): activated silica - natural diatomite, thermally treated at 200C -10-30, carbonateous slurry (a by-product of thermal power station water softening) - 10-20. ^ EFFECT: preventing erosion and corrosion of buildings and structures; minimisation of the expenditures related to cosmetic repairs of buildings and structures under operation; saving the necessity to perform costly renovation during the period between overhauls. ^ 1 tbl
