Conclusions
-
1.
It was established that the use of the complex additive WCA+FM+SYL is the most effective when producing highly fluid (mushy) concrete mixes.
-
2.
Complex additives substantially improve cohesiveness, workability, and keeping qualities (with respect to fluidity) of the mix, and also considerably reduce its segregation during placement in the structures being concreted.
-
3.
The use of mushy mixes reduces labor expenditures on concreting geometrically and technologically complex structures, improves the conditions of performing the works, and shortens the construction time.
