Essay

The cement-water composition SPCWC with low W/C, high flow ability, high strength and kinetics of hardening at under temperature. The representations about reological characteristics, hydration and structure formation SPCWC, and also structure and strength of the cement stone from SPCWC are advanced. The criterions of viscosity, W/C and strength of the cement stone from SPCWC are established, on the basis of these yardsticks the optimum structures SPCWC are determined. Designed composition successfully has passed tests and introduction on an experimental section mining tunnel on Lviv railway, on Kharkiv underground, and also repair bridge abutment on Southern railway.
