The modulus of elasticity of normal weight concrete is 9400 ksi.
The modulus of elasticity is the measure of the stiffness of a substance. It measures the resistance of an object to being deformed.
Generally, the objects with higher values of modulus of elasticity are stronger and therefore preferred to be used as a building material for construction purposes.
The relation between the compressive strength(C) of a substance and its modulus of elasticity(E) is given by the following formula;
E = 4700√C ksi
We are given that the compressive strength of normal weight concrete is 4 ksi,
Therefore, E = 4700 √4
E = 9400 ksi
Thus, the modulus of elasticity of normal weight concrete is 9400 ksi.
