This study represents the investigation of experiment which is carried out to find the effects of replacement of coarse aggregate with the slag of blast furnace on various properties of concrete. The objective of the study is to find out the alternate source of aggregate of high quality because quarries of natural stones are depleting with drastic speed due to lots of construction activities occurring in India. Thus, the effects on compressive strength of cubes is evaluated by replacing slag with aggregate of natural course, also the flexural strength and split tensile strength is evaluated for beams and cylinders respectively. Slag which is a waste byproduct of steel and iron production gives an opportunity to use it as an alternative to available aggregate. The test results were obtained of concrete by mixing slag with coarse aggregate in various percentages i.e. 0, 20, 40, 60 and 100 Percentages respectively. Before testing all the prepared specimens of concrete were cured for a period of 28 days. It has been observed from the study that the slag aggregate of blast furnace can be used as a good alternate of stone aggregate.
