Beschreibung
Zusammenfassung:	A rapid hardening dry building mixture for restoration of damaged concrete contains as base gypsum-free Portland cement, aluminium sulfate and chemically active component consisting of calcium salt ofweak inorganic acid, plasticizer, rust transformer, corrosion inhibitor, sodium nitrate, sodium carbonate, calcium hydroxide or calcium carbide, sodium sulfate, calcium chloride. The mixture can be used for tightening orifices, cracks, joints, gaps, rapid removal of building structures leak on concrete, reinforced concrete and other mineral capillary-porous hard bases, in repair or emergency operations, for forming hydroisolation water-proof and protective coatings etc. While use of dry constructive mixture it is mixed before use with water at W/T=0.2-0.3. The protective layer of proposed composition has an increased strength, water tightness and frost resistance.
