  The influences of water to cement(W/C)ratio and fineness on the autogenous shrinkage of cement paste were investigated.Cements with different fineness were classified from a commercial Portland cement by an air-classifier in the laboratory.The autogenous shrinkages of cement pastes were measured by a non-contact corrugated method.
