Effects of Supplementary Cementitious Materials on the Long-Term Durability Properties of Concrete
The incorporation of supplementary cementitious materials (SCMs) in concrete can lower the carbon footprint and improve the durability performance. This research focused on studying the effects of different SCMs such as class F fly ash (FA), reclaimed fly ash (RFA), and ground bottom ash (GBA) on the long-term durability properties of concrete containing 10%, 20%, and 30% replacement levels. Long-term durability properties of concrete, including drying shrinkage and alkali-silica reactivity (ASR), were determined along with the workability (slump) and compressive strength. Experimental results showed that FA and RFA-modified concrete exhibited higher workability than GBA-modified concrete. However, GBA-modified concrete achieved the highest compressive strength at the 30% replacement level. Concrete modified by each SCM demonstrated lower drying shrinkage and ASR expansion than conventional concrete. Considering the overall performance of concrete (drying shrinkage, ASR, workability, and compressive strength), a 20% replacement level of all SCMs would be optimum content.
