21 What is the fundamental property of water that makes wate

21. What is the fundamental property of water that makes water and chemicals move into concrete by sorptivity? 22. Calculate the value of the Modulus of Elasticity of a high-strength concrete sample when its compressive strength is 10,000 psi? (show calculations)

Solution

Answer 1. Sorptivity is the ability or tendency of a material to absorb or desorb liquids by capillary mechanism.

Answer 2. Modulus of Elasticity (E_S ) = 57000(f`c)^0.5

=57000*(10000)^0.5

Modulus of Elasticity(E_S )   = 5700000 psi
