Abstract:
This paper outlines a detailed study on the use of Waste Glass Powder (WGP) and Waste Glass Sand (WGS) with Fly Ash (FA) and Silica Sand (SS) replacements in Engineered Cementitious Composites (ECC). It investigates the effect of different replacement levels of WGP and WGS on the mechanical, physical and selfhealing efficiency of ECC’s. For this purpose, mixtures were prepared with 0, 15, 30, 45 and 60% of FA replacement by weight of WGP, and SS was replaced with 0, 25, 50, 75 and 100% by weight of WGS. Compressive and flexural strengths, mid-span beam deflection capacity, rapid chloride penetrability and resistivity were tested to assess the mechanical, physical and self-healing performances of different sound and preloaded specimens. The results of this study showed the possibility of replacing FA by WGP, and SS by WGS in the production of different ECC’s. Optimum mechanical, physical and self-healing characteristics were obtained for ECC mixtures including up to 30% of WGP or up to 50% of WGS replacement level. Alkalis and aluminum based-C-S-H with low Ca/Si was the main healing product in the healed crack lines of WGP- and WGS- based ECC’s.
