Review article

The usage of carbonate rocks as mortar aggregates has been technically and economically substantiated in the production of lime dry mixtures for restoration. The paper considers the effect of replacing a part of quartz sand in lime mortar by the removal of limestone sand and dolomite filler on the compressive strength, adhesion to ceramic brick and vapor permeability. A matrix of planning experiments is proposed. This matrix allows increasing the information content of the research results and reducing the number of experiments in the search for optimal solutions. The efficiency of replacement of quartz aggregate by the carbonate rocks waste in the production of dry mixtures for restoration is shown.
