When a specimen of M25 concrete is loaded to a stress level of 12.5 MPa, a strain of 500 × 10–6 is recorded. If this load is allowed to stand for a long time, the strain increases to 1000 × 10–6. In accordance with provisions of IS: 456-2000, considering the long-term effects, the effective modulus of elasticity of the concrete (in MPa) is ________

    To calculate the strain, we need to use Hooke's Law, which states that strain is directly proportional to stress. The formula is:

    Strain = Stress / Young's Modulus

    First, we need to determine the Young's Modulus of M25 concrete. The Young's Modulus of concrete typically ranges from 25 to 30 GPa (Gigapascals). Let's assume it is 28 GPa for this calculation.

    Young's Modulus = 28 GPa = 28,000 MPa

    Now we can calculate the strain:

    Strain = Stress / Young's Modulus
    Strain = 12.5 MPa / 28,000 MPa

    Converting MPa to GPa:
    Strain = 12.5 / 28,000
    Strain = 0.0004464

    Therefore, when a specimen of M25 concrete is loaded to a stress level of 12.5 MPa, the strain is approximately 0.0004464.
