#### 73. Uniaxial Compressive Behavior of Concrete

· Concrete is a brittle material, which means, it fails suddenly when the stress due to external load reaches it's ultimate strength. For example, a concrete cylinder with a compressive strength of 20 mPa (M20 according to Indian Standard), fails when the stress due to external load reaches slightly higher than the value.

#### determines the compressive strength of concrete

The concrete mix is an important aspect of RCC slab because it determines the compressive strength of concrete and also its durability in terms of weather resistance and water permeability. In engineering practice, the concrete mix is denoted by M15, M20, M25 (and more richer mixes as well). where the number denotes the strength of a cube in N/mm2 of concrete made using similar mix proportions.
