Prospects of application of roller compacted concrete in hydro schemes of Ukraine

Prospects of application roller compacted concrete in hydro schemes Ukraine are considered. The number dams erected with is growing year after the world. Roller an especially dry mixture decreased content cement and increased pozzolana (fly ash). broad physico-mechanical peculiarities depend not only on its composition but also technology laying compacting dam. Rapid construction gravity use equipment for earth-moving works enables more economic protective embankments. during erection restoration existing embankments regions flood hazard west allows reducing deadlines by a factor 2–3, and, so doing, labor 4–5 at expense full mechanization works. Decrease binder 30–80 kg/m3 favors decrease heat release correspondingly, occurrence temperature contraction cracks, which turn economy hydro-technical structures schemes.
