Abstract

This study examines both strength development and pore volume of high temperature curing mortar, using a blast-furnace slag powder (BFS). This study experiments with various pre-steaming period, differing curing temperature and the replacement of BFS. According to the results, the strength development of BFS mortar is stronger when higher curing temperature are used(as opposed to standard curing). Also, regardless of the curing method, pore volume decreases as the curing time increases. From these results we can identify the optimum conditions required pre-steaming period, differing curing temperature and the replacement to produce BFS mortar properties.
