Abstract

This study is to analyze the properties of concrete according to the types of binders and cement powder and to utilize them as fundamental data for the development of early strength concrete. In the case of fluidity, all of the formulations satisfied the 180±25mm, and the flowability of HSF was decreased by high fineness cement. For the air content, 4.5±1.5% of the total content was satisfied. Compressive strength of HSF was found to satisfy the 5MPa in 2days of aging. In case of 28 days of aging, the strength of HSF was more than 24MPa.
