METHOD OF REDUCING INTENSITY OF SALT EFFLORESCENCE FORMATION ON SURFACE OF CEMENT MORTAR MASONRY Russian patent published in 2008 - IPC C04B28/04 C04B14/08 C04B18/04 C04B111/70 

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 200°C -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.
