Abstract
The need for sustainable power generation resources is increasing day after day. Among many countries around the world, Canada is considering elimination of coal plants. This is causing a shortage in the supply of good quality fly ash minerals. Recent research on the production of engineered cementitious composites (ECC) focused on utilizing of Class F Fly Ash. Hence, this study was designed to experimentally investigate the influence of partial and full replacement of slag with fly ash on the mechanical and durability performance of ECC mixtures through a comprehensive experimental program. Test results from this study showed that slag containing mixtures exhibited strain-hardening behaviour and a comparable or similar ductility characteristics as fly ash containing mixtures. Moreover, incorporating slag in the mixtures were found to be effective in reducing permeability in terms of rapid chloride penetration, sorptivity, and water absorption at both 28 and 90 days. However, mixtures containing slag had higher drying shrinkage strains when compared to fly ash mixtures.
