In drying shrinkage, the excessive water which has not taken part in hydration process would migrate from interior of concrete core to the concrete surface. As a result of evaporation of the water moisture, the volume of concrete shrinks. The reduction in volume owing to moisture loss is termed shrinkage. In fact, aggregates in concrete would not cause shrinkage and helps to resist the deformation.
