  • How Concrete is Made

    The longer the concrete is kept moist, the stronger and more durable it will become. The rate of hardening depends upon the composition and fineness of the cement, the mix proportions, and the moisture and temperature conditions. Concrete continues to get stronger as it gets older.

    Concrete Mix Ratios - Cement, Sand, Aggregate and Water

    Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.
