The invention relates to building branch and can be used in repair, hydroinsulation and other building works. Composition material for emergency repair and restoration of concrete and stone structures contains, weight %: sodium nitrate – 0.50-0.40, calcium chloride – 0.40-0.30, sodium carbonate – 0.40-0.30, calcium hydroxide or calcium carbide – 0.80-0.70, sodium sulphate – 0.40-0.30, corrosion inhibitor – 0.10-0.20, plasticizer – 0.05, rust solvent – 0.05, nonwoven fabric of bulk structure – 0.30-0.70, ground clinker of portland cement – 96.00, potassium carbonate – 1.00. The use of the invention provides quick removal of water filtration through concrete or other stone structure. The proposed material has reduced terms of hardening: beginning – 1.2 min., the end – 2.2 min., high hardness, water resistance indexes, coupling with basis. |
