Abstract:
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, 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.
