Experience of stage-by-stage modification of heavy concrete with superplasticizer S-3

The article presents the results of secondary modification of heavy concrete by introducing an aqueous solution of plasticizer C-3. It is established that secondary introduction of C-3 under certain conditions does not reduce the strength or frost resistance of concrete, and allows to improve its workability after long transportation. Recommendations providing for successful secondary modification of concrete are given.
