Pozzolanic admixtures are generally being used along with the cement in concrete mixes so as to derive certain benefits like economy, durability, Chemical resistance in permeability etc. The use of high volumes of fly ash has become on of the current topics of research possibility promoted by the availability of a wide range of chemical and mineral admixtures. Test results of the study show that the designed strength was exceeded and that the ductility ratio and the safety margin against brittle failure of concrete containing these industrial by-products were comparable to those of the reference concrete (normal ordinary Portland cement concrete), proving the feasibility of using the waste materials as alternative construction materials. Different water-binder ratios ranging from 0.55 to 0.27are considered for investigation. From the results, the relationship is developed between Compressive Strength, Split Tensile strength and Flexural Strength of High Volumes of Slag Concrete. Test results show that strength increases with the increase of slag up to an optimum value, beyond which, strength values start decreasing with further addition of slag. Among the seven slag mortars, the optimum amount of cement replacement is about 40%, which provides 19% higher compressive strength and 25% higher tensile strength as compared to OPC mortar.
