The purpose of the present study is to explore the autogenous shrinkage of high-performance concrete with mineral admixture and to derive a realistic equation to estimate the autogenous shrinkage model of that. For this purpose, several series of concrete specimens have been tested. Major test variables were the type and contents of mineral admixture and water-binder ratio is fixed with 30%. The flow rate, compressive strength and autogenous shrinkage were measured for the specimens. The present study indicates that the test specimens have the properties of high-performance concrete. The autogenous shrinkage of HPC with fly ash slightly decreased than that of OPC concrete, but the use of blast furnace slag and silica fume increased with the autogenous shrinkage. A prediction equation to estimate the autogenous shrinkage of HPC with mineral admixture was derived and proposed in this study. The proposed equation show reasonably good correlation with test data on autogenous shrinkage of HPC with mineral admixture.Read More
