The effects of replacing cement by steel slag on the compression strength of cubes, split tensile strength of cylinders and textural strength of beams are evaluated in this study. steel slag is obtained as waste product from the sterlite industries. Investigations were carried out to explore the possibility of using steel slag as a replacement of cement in concrete mixtures. The test results of concrete were obtained by adding steel slag to cement in various percentages ranging from 10%, 20%, 30%.All specimens were cured for 7 days, 14 days and 28 days before compression strength test, splitting tensile test and flexural strength. This results of the research paper showed that the possibility of using steel slag as cement in concrete. The results showed the effect of steel slag on concrete elements has a considerable amount of increase in the compressive, split tensile, flexural strength characteristics and energy absorption characteristics. No additional catalyst/plasticizers have been used.

REVIEW OF LITERATURE:
Jabri, Makoto Hisadaet. alhas published paper on the research study was conducted to investigate the performance of high strength concrete (HSC) made with steel slag as a fine aggregate at constant workability and to study the effect of super plasticizer addition on the properties of HSC made with steel slag. Two series of concrete mixtures were prepared with different proportions of steel slag.
The first series consisted of six concrete mixtures prepared with different proportions of steel slag at constant workability. The water content was adjusted in each mixture in order to achieve the same workability as that for the control mixture. Twelve concrete mixtures were prepared in the second series. Only the first mixture was prepared using super plasticizer whereas the other eleven mixtures were prepared without using super plasticizer and with different proportions of steel slag used as sand replacement. The results indicated that the water demand reduced by almost 22% at 100% steel slag replacement compared to the control mixture.
The strength and durability of HSC were generally improved with the increase of steel slag content in the concrete mixture. However, the strength and durability characteristics of HSC were adversely affected by the absence of the super plasticizer from the concrete paste despite the improvement in the concrete strength with the increase of steel content. All concrete mixtures did not meet the strength and durability design requirements due to the segregation and dryness of the concrete paste. Therefore it can be concluded that the use of steel slag as sand substitution improves HSC strength and durability characteristics at same workability while super plasticizer is very important ingredient in HSC made with steel slag in order to provide good workability and better consistency for the concrete matrix.
Junwei Songet. alhas suggested an introduction of the current situation of comprehensive utilization of steel slag from different aspects in domestic and overseas, and puts forward the problems existed in the comprehensive utilization of steel slag. It has been found that steel slag have micro pozzolanic effect in the study. Workability of steel slag concrete is poor, but mixing the appropriate amount of micro-aggregates can improve their workability significantly. The mechanism of steel slag powder in composite cementitious materials is filling effect, activity effect and acceleration effect. The filling effect of steel slag can make matrix denser and the accelerating effect can accelerate the early hydration. Test and analysis are made on the influence of steel slag on strength and brittleness of concrete. Brittleness of concrete can decreased by adding steel slag, and mechanism is analyzed.
Vamsi Pradeep I, Kishore Kumar M et. al explained thatthis paper, research has been carried out on the effect of steel slag on the strength properties of both M25 and M30 concrete. Cement was replaced with steel slag in following proportions: 0%, 5%, 10%, 12%, 14%, 16%, 18% and 20%.There was remarkable variation observed in the stress patterns. Tabulated values have been provided depicting the variation pattern of both direct and in-direct stresses. The concrete was tested for 7 days and 28 days strength after casting the moulds. No additional catalyst/plasticizers have been used.
