Abstract: In this study, the fresh and hardened properties of concrete produced from stone dust as fine aggregate and with the incorporation of jute fibre were analysed by employing the response surface methodology. Two independent variables, i.e., cut length (0-15 mm) and volumetric percent of jute fibre (0-0.15%) and their five responses (7-day and 28-day compressive strength, 7-day and 28-day splitting tensile strength and slump value) were considered to develop statistical models. From the response surface plot, it was observed that both compressive strength and tensile strength increases with the increase of both variables. Moreover, it was observed that the maximum compressive and split tensile strength is obtained for 15 mm cut length and with the addition of 0.10% and 0.15% jute fibre respectively. Furthermore, the slump values show a declining trend with the increase of both variables. Finally, the probabilistic models have been found statistically significant from the analysis of variance.
