As a new type of dam, roller compacted concrete dam (RCCD) develops very fast in recent years. Deformation plays an important role in the RCCD’s safety. The deformation of RCCD is influenced mainly by three parts: water pressure, temperature and time effect. As to any of the three parts, there are many factors. Therefore, the deformation of RCCD is a complicated system. The least squares suppor...

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 eq...
