USE OF AIR COOLED BLAST FURNANCE SLAG (ACBFS) AS COARSE AGGREGATES‐ A CASE STUDY
Resources are depleting day by day due to non consumptive use by the mankind. Blast furnace slag has a great potential as it can be used as an artificial aggregate. Keeping this in view, the present study the present study encourages the utilization of waste material such as air cooled blast furnace slag (ACBFS) and fly ash in concrete. The combined effect of ACBFS as replacement for coarse aggregates and fly ash as a partial replacement of cement on the compressive and flexural strength of concrete has been investigated. Six mixes were prepared at different replacement levels of ACBFS (0%, 20%, 40%, 60%, 80% and 100%) with coarse aggregate and fly ash was at 10% constant in all mixes. The compressive strength of concrete and flexural strength was tested after 3, 7 and 28 days of curing. Results indicate that the compressive and flexural strength are in phase with each other. The replacement of ACBFS with coarse aggregates up to 40% increases the compressive and flexural strength of concrete and at 60% there is marginal decrease in both parameters. On further replacement up to 80% and 100% the compressive and flexural strength of concrete mix decreases significantly. As it was observed that compressive and flexural strength increases with replacement up to 40% ACBFS, it is recommended that up to 40% of ACBFS can be used as coarse aggregate in concrete. https://www.ijiert.org/paper-details?paper_id=140167
