Abstract:
Basic studies were conducted to develop high-performance concrete, with low-heat and high-strength characteristics under low-temperature environments, using blast furnace slag. The purpose of this study was to clarify the effects of slag fineness, slag content, gypsum content, limestone-powder content, and high-range water-reducing admixtures (HRWRA) on the strength development, adiabatic temperature rise, porosity, amount of Ca(OH) 2, and carbonation of concrete; and the effect of curing temperature on concrete strength development. As a result of this study, it was found that it is possible to produce high-performance concrete with low heat and high strength under low-temperature environments, by properly combining, and taking into consideration, their respective properties, granulated blast furnace slag, HRWRA, and other admixtures.
