What is the Loss of Prestress due to Shrinkage of Concrete

It is the loss of prestress due to shrinkage of concrete, which takes place in the initial stage of hardening of concrete. Due to shrinkage of concrete, compressive strains in concrete increase (so the tensile strains in tendons decrease to the same extent) and consequently there is a loss of prestress in the concrete member.
