Abstract:   Due to the auspicious attribute of concrete such as durability, availability, versatility, good compressive strength, it is one of the most commonly used building materials throughout the world. The demand for infrastructural facilities is increasing day by day which creates a tremendous pressure on concrete as well as on natural aggregates. Apparently it becomes unavoidable to look for alternative materials. On the other
hand, disposal of stone dust generated from stone crusher is becoming a problem. Substituting sand by stone dust will serve the waste management as well as the alternative material in concrete. The present research’s aim is to find out the strength aspect of concrete by using stone dust as a partial replacement of sand. The test specimens were made from three different grades of concrete i.e. mix ratios 1: 1.5: 3, 1: 2: 4, 1: 2.5: 5 and both compressive as well as tensile strength tests were conducted. The basic strength properties of concrete were investigated by replacing natural sand by Stone dust at replacement levels of 0%, 10%, 20%, 30%, 40%, 50% & 60%. For the different grades of concrete studied, the value of the compressive strength are observed to be maximum at 30% replacement level of sand whereas the maximum tensile strength occurs at 20% replacement level. The result shows that the maximum increase in compressive and tensile strength are 15% and 12% respectively in comparison to normal concrete (0% sand replacement level) for the concrete mix-ratio 1: 1.5: 3.
