The aim of this study is to study the effect of manufactured sand and river sand on the setting time of concrete. The investigation proceeds by changing the proportion of fine aggregate from 100% river sand to 100% manufactured sand. In this process six different concrete mixes are adopted by varying the proportions of the fine aggregates used, i.e: 100% river sand, 50% river sand and 50% manufactured sand, 40% river sand and 60% manufactured sand, 30% river sand and 70% manufactured sand, 20% river sand and 80% manufactured sand, 100% manufactured sand. The effect on the setting time of concrete is studied through penetration resistance method as per IS Code:8142-1976
