Mechanical properties of concrete such as compressive strength and elastic modulus are affected by the moisture inside the concrete members. Concrete specimens with various diffusion conditions are tested and the relations between the pore relative humidity and mechanical properties are suggested based on the experimental results. Suggested models are applied to the experimental results in the previous researches and the comparison results show that the models are reasonable.
