Studies on mortars containing waste bottle glass and industrial by-products

This study presents investigation of properties of cement-based mortars produced with cement containing waste glass (WG) and industrial by-products. The features, compressive strength, sulfate and chloride resistance, high temperature resistance, and expansions related to alkali-silica reaction (ASR) are examined. Three series of mortar specimens containing ground WG are prepared. Only ground WG is replaced cement in the first series. Ground WG, ground granulated blast-furnace slag (GGBFS) or fly ash (FA) is replaced cement in the second and third series. The results showed that compressive strength was decreased as replacement level increased. The observed losses in early strength of mortars were relatively higher than strength losses measured at 28th day. Minor increases in strength were obtained at 10% and tolerable decreases in strength were observed at 30% replacement levels. The same trend is also valid for durability properties examined in this study. Hence it is concluded that combined usage of WG and GGBFS, or WG and FA will be more suitable instead of using WG alone in mortar. (C) 2007 Elsevier Ltd. All rights reserved.
