Abstract
Super low-heat cement is effective in controlling thermal cracks in mass concrete structures. Therefore, eight kinds of super low-heat cement with substantial additions of pulverized blast-furnace slag and fly ash were trial-manufactured and their applicabilities to mass concrete structures were investigated through the properties of concretes using these cements. It was found that replacement further of fine aggregate with pulverized limestone produced a concrete which was plastic and exhibited low temperature rise to facilitate inhibition of thermal cracking of mass concrete structures.
