    Desired properties of concrete. Hardness, cohesiveness and strength: Concrete must be resistant to freezing, thawing, water tight ( non permeable), wear resistance, and strength. Economy: Since the quality mainly depends on the w/c ratio, the water requirement should be minimized to reduce the cement requirement and hence cost.

  • Properties of Reactive Powder Concrete and Its Application

    A high-performance reactive powder concrete (RPC) was prepared with river sand, and the maximum particle size is 1.25 mm, under the 80C steam curing condition. It is tested completely in terms of strength, uniaxial compressive stress-strain relation, flexural load-deflection relation, and frost resisting durability, and the results indicate that the concrete is suitable to RPC200.
