The mechanical characteristics of green ternary cement paste incorporating blast furnace slag and palm oil fuel ash

Abstract

This study investigated the use of different amounts of BFS and POFA. In all mixture systems, 60% cement was replaced with POFA and BFS as a substitute for Ordinary Portland Cement. The results show that with the addition of POFA and BFS, although the early compressive strength will be reduced, the strength will be significantly improved at 28 days. In the ternary system, the 28-day strength is negatively correlated with increasing POFA content.
