An Experimental Study on Evaluation of Creep and Shrinkage for Blast Furnace Slag-Cementless Concrete with Compressive Strength of 80 MPa

In this study, the long-term behavior of 80 MPa cementless concrete incorporating blast furnace slag and that of ordinary concrete with the same compressive strength were evaluated. The modulus of elasticity, autogenous shrinkage, and basic creep coefficient of the cementless concrete were found to be comparable to those of ordinary concrete. In contrast, the drying creep and drying shrinkage of the cementless concrete were observed to be lower than those of ordinary concrete.
