ABSTRACT
Abstracts This study examines how the autogenous shrinkage stress in high-fluidity concrete is affected by the aggregate crushing value of coarse aggregate and its volume per unit volume of concrete. The following findings were obtained. The autogenous shrinkage stress is not affected by aggregate crushing value, but is reduced when the coarse aggregate's volume per unit volume of concrete increases due to the restraining effect of coarse aggregates. Autogenous shrinkage is reduced by using light-weight aggregate, which has high absorbtion of water. Keywords: Aggregate crushing value, autogenous shrinkage stress, high-fluidity concrete, light-weight aggregate, quality of coarse aggregate.
