Influence of the complex modifier on concrete durability is investigated. It is established that introduction of Glenium ACE 430 softener reduces concrete’s water requirement by 17-30% keeping identical mobility. Use of Glenium ACE 430 supersoftener with out CEED 100 X-accelerator reduces concrete durability by 5% in comparison with an exemplar without modifier, however on 3 and the 28th days durability increase for 18% and 22% respectively is observed. The increase in durability three times exemplars with the maintenance of Glenium ACE 430 and an accelerating agent of X-CEED 100 in comparison with an exemplar without modifiers for the first days, twice on 3-and days, 1,5 times on 28-е days is observed. Decrease in a consumption of cement from 400 kg/m3 to 345 kg/m3 is expedient since it does not lead to strength reduction concrete’s durability with the complex modifier.
