Abstract

The effect of accelerating admixtures for curing and properties of concrete on the basis
of slag Portland cement is examined. Such highly active mineral admixtures as microsilica,
metakaolin, sodium formate and calcium formate are used as accelerators. It’s found out that
the most effective hardeners and modifiers of a concrete matrix structure are the complexes
including polycarboxylate superplasticizer Glenium Ace 430 with sodium formate and Ace 430
with microsilica.
