The effect of wetting and drying cycles on the durability performance of cement concrete.
Dear Dr. Saleh,
Cycles of wetting and drying and temperature changes cause expansion and shrinkage and, hence, volume changes in concrete. These volume changes produce internal stress cracking inside the concrete.

It causes volumetric expansion and contraction in the concrete and thereby generates stresses in the concrete. As we know, concrete can sustain the compression stresses but on the application of tensile stresses it will deteriorate. This is similar to the effect of curling stresses in pavement slab owing to change in temperature between top and bottom.
Yes, the cycles of wetting and drying changes cause expansion and shrinkage and, hence, volume changes in cement concrete. These volume changes produce internal stress cracking inside the concrete.
In marine environment, the structural cement concrete in tidal zone undergoes alternate wetting and drying process due to tidal action, resulting in expansion and shrinkage and, hence, volume changes in cement concrete and consequently stresses in the concrete.
Dear Dr. Surender Singh, thank you so much for your interesting and valuable comments.
