Abstract: This paper presents the value creation opportunity of black marble stone waste as fine aggregate in the concrete mix. Five concrete mixes are prepared by replacing the natural sand with stone waste as fine aggregate in the ratio of 0%, 25%, 50%, 75% and 100% by weight. The experimental study is focused to evaluate the properties of compressive and split tensile strengths. The strengths were compared with ACI 318-M-11 and GB50010-2002 codes. From the results it is noticed that, the codes are underestimates the real strengths. Hence a regression model was developed to estimate the results and also microscopic analysis was carried out to using SEM analysis. SAP-2000 analysis was performed to obtain the stress variation in the concrete cube. From the results is observed that, the black marble stone waste can be used up to 75% replacement of fine aggregate (natural sand) without affecting the desirable strength.
