    Dec 16, 2016· Concrete has relatively high compressive strength, but significantly lower tensile strength. The elasticity of concrete is relatively constant at low stress levels but starts decreasing at higher stress levels as matrix cracking develops. Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete

  • Reinforced Cement Concrete Advantages, Uses, Types

    Reinforced cement concrete (R.C.C) is the combination of ordinary concrete with the reinforcement to increase its compressive and tensile strength to a great extent. Concrete is a versatile material for modern construction which is prepared by mixing well-proportioned quantities of cement (even lime in some cases), sand,crushed rock or gravel

    Reinforcement Ratio The amount of steel reinforcement is limited. Too much reinforcement, or over-reinforced will not allow the steel to yield before the concrete crushes and there is a sudden failure. A beam with the proper amount of steel to allow it to yield at failure is said to be under reinforced. The reinforcement ratio is a fraction: bd A
