FIELD: chemistry.
SUBSTANCE: invention relates to compositions for repair or restoration of horizontal and vertical surfaces of structures made of concrete and reinforced concrete in difficult climatic conditions. Composition consists of more than 30 wt.% of methyl methacrylate, not more than 10 wt.% of a polymerisation initiator and fillers are the rest. Fillers are represented by different-fraction quartz sand, and/or quartz flour, and/or gabbro-diabase, and/or pigments, and/or dyes, as well as a water-based thickener.
EFFECT: faster repair of horizontal and vertical surfaces, higher frost resistance.
