Analysis of salt patches on brickwork of constructed buildings and identification of causes of their appearance // Problems in the rational use of natural and technogenic raw materials from the Barents region in construction and technical material technology.

Brick mortar was tested to determine the causes of salt patches appearance on the brickwork of buildings. It was found that the mortars mixed in different seasons (February, April, May) had high content of calcium oxide (8.64-16.67%). High content of alkaline oxides (26.74%) and SO3 (16.4%) was observed in salt patches. Salt patches appear due to the presence in the mortar of insoluble calcium carbonate and sodium sulfate as well as due to excess of
moisture in the mortar and air.
