A STUDY ON THE SHRINKAGE CRACK RESISTANCE OF SELF-COMPACTING CONCRETE

This study looked at the effects of powdered additives used in conjunction with self-compacting concrete and the varying resistance levels to shrinkage crack due to autogenous and drying shrinkage. Resistance was estimated by comparing the cracking ages of the concrete under restrained conditions. The powdered materials used were normal portland cement, low-heat portland cement, portland blast furnace slag cement, and two blends of normal portland cement and limestone powder (the blending volume ratios of limestone powder were 30% and 55%). From the results of the experiments, it became clear that the resistance level of self-compacting concrete to shrinkage crack was quite different depending on the type of powdered materials used.
