FIELD: chemistry.
SUBSTANCE: invention relates to preparation of coarse concrete aggregates. The cement lining composition for coarse aggregate contains the following in wt %: portland cement 65.0-67.0; urea 0.7-1.1; casein glue 6.0-7.0; carboxymethyl cellulose 0.03-0.04; superplasticiser C-3 1.5-1.9; water - the rest.
EFFECT: high adhesion of the cement lining to the surface of the coarse aggregate.
