Abstract
This study investigates the long-term durability of concrete by replacing cement (10%, 20%, and 30%) with four potential Supplementary Cementitious Material (SCMs), namely, Reclaimed Fly Ash (RFA), Ground Bottom Ash (GBA), Class F Fly Ash (FA), and Metakaolin® (MK). For long-term durability, drying shrinkage and alkali-silica reactivity (ASR) tests were performed along with workability (slump) and compressive strength tests. The FA and RFA demonstrated better workability compared to GBA, MK, and combined mixes (RFA-MK or GBA-MK). The GBA and RFA modified specimens exhibited better compressive strength than other SCMs. Modifying concrete mix with SCMs lowered the ASR expansion than the concrete mix without any SCM and at a 30% replacement level with SCM showed the lowest expansion in most cases. The drying shrinkage was also got reduced by the pozzolanic reaction of SCMs. The combination of MK with RFA or GBA alone performed better in reducing the drying shrinkage.
