(54) COMPOSITION FOR QUICK-SETTING BINDER CONTAINING CALCIUM SALT FOR CONCRETE OBJECTS AND STRUCTURES
SUBSTANCE: invention can be used for preparing concrete objects and structures. The quick-setting binder contains cement, at least one superplasticiser, calcium nitrite and at least one formol derivative – formaldehyde or formic acid, or its salt with an alkali or alkali-earth metal, or formaldehyde-bisulphite of an alkali or alkali-earth metal, or formaldehyde-sulphoxide of an alkali or alkali-earth metal. Accelerating system for the said binder. Composition of a concrete or mortar prepared using the said binder. A method of preparing concrete mixture or mortar by tempering the said binder with water. A method of making objects from the said composition or concrete mixture or mortar, obtained using the said method, which involves pouring or discharging the said composition or concrete mixture or mortar into a mould, hardening and removal from the mould at temperature not above 10°C with the method running for 1/2 days. The invention is developed in subclaims.
EFFECT: preservation of workability of concrete on quick-setting binder, faster growth of mechanical strength at temperature below 10°C, increased frequency of using the mould.
