Abstract:
Due to the tendency of hydrated portland cement to shrink or swell with loss or gain of water, moisture gradients produced by rapid drying may induce stresses in concrete and mortar. The research described in this paper shows that these stresses can be of sufficant magnitude to significantly reduce the tensile strength of concrete and mortar.
