Abstract
In this study, petroleum cokes ash and $C_{12}A_7$-based slag were used for the shrinkage reduction and strength enhancement of mortar. The hydration properties of shrinkage reduction agents were analysed. The flow, change of length and compressive strength were experimented with mortar-added shrinkage reduction agents. As a result of this study, petroleum cokes ash : $C_{12}A_7$-based slag = 60~80% : 20~40% showed excellent results. In the case of mortar with 20% $C_{12}A_7$-based slag, the setting time and change of length were similar to Ref. mortar. The flow and compressive strength were superior to Ref. mortar. In the case of mortar with a 40% $C_{12}A_7$-based slag, the setting time was longer than Ref. mortar. The compressive strength of 3 days and 7 days were superior to Ref. mortar.
