Functional Performance and Comparative Sustainability Assessment of Cementitious Composites Using Supplementary Cementitious Materials (SCMs)

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To evaluate the potential of fly ash (FA) and ground granulated blast furnace slag (GGBFS) as supplementary cementitious materials (SCMs) in terms of sustainability and functional performance, both concrete and mortar samples were prepared with GGBFS or FA at moderate to high replacement ratios (35%, 50%, and 65%) and were tested for compressive ...
