At present the use of Ferrous Slag (FS) in concrete gives environmental and economic benefits for concerned industries, especially in places where a considerable amount of FS is produced. Owing to the scarcity of sand for the preparation of mortar as well as concrete, partial and fully replacement of FS with sand have been attempted. FS are by-products obtained during smelting and refining of FS. This work reports an experimental procedure to investigate the effect of using FS as partial replacement of sand. Six series of concrete mixtures were prepared with varies proportions of FS ranging from 0% to 100%. The test results of concrete were obtained by adding FS to sand in various percentages ranging from 0%, 20%. 40%, 60%, 80% and 100%. All specimens were cured for 7 & 28days before compression strength test etc. Results that workability increases with increase in percentage of FS and feasibility study on the use of broken Mangalore tiles as coarse aggregate in combination with iron ore slag in the production of low to medium strength concrete is carried out.
