FIELD: construction.
SUBSTANCE: invention is related to industry of construction materials, namely to compositions of paste fillers on the basis of mineral binder, fillers, plasticising additives, which may be used for filling of wood, concrete, reinforced concrete surfaces of buildings, structures, and also for cosmetic coating of metal embedded parts in reinforced concrete structures, for sealing of seams and cracks in buildings of bricks and wall construction stones, in particular from slag stones. Paste filler contains the following components, wt %: slag Portland cement 35-40; wastes of water concentration of iron ores with particle size of less than 1 mm, also around 30% - with size of less than 0.01 mm, 40-50; carboxymethylcellulose 0.2-0.9; complex plasticising additive "Relamix, type 2" 0.01-0.08; fly ash from burning of black coal, wood, peat - the rest.
EFFECT: improved technological properties of paste filler, increased plasticity, viscosity, strength, reduced crack formation.
