FIELD: construction materials and products.
SUBSTANCE: pre-layout restoration and repair compositions of white stone architecture. The composition of the cementless pre-composition mixture consists of the following components, wt. %: slaked lime 40-50; water 14.9-23.5; quartz flour 9-13; liquid potassium glass 5; plasticizer Melflux 0.1-0.5; sodium caseinate 3-4; ceramic microgranules 10-15; cellulose microfiber 2; white soot – silica 2.
EFFECT: creating compositions designed to preserve the original appearance of structures, replenishing lost operational ability and preventing the formation of fungal mycelia and gypsum crust on the surface of objects, increasing physical and mechanical properties.
