Abstract
- This paper investigates the experimental analysis of concrete mixtures with different percentages of manufactured sand replaced for natural sand, with a focus on M25 and M30 grades. The study analyses various repairing times, with a special focus on 3, 14, and 28-day periods. The main conclusions show a clear pattern, with the maximum compressive strength for M25 and M30 grades being found at 50% and 100% replacement levels, respectively. This positive connection indicates that the amount of manufactured sand incorporation affects the compressive strength and shows its effect over different curing times. It is noteworthy that self-compacting concrete (SCC) made using crushed sand has a higher compressive strength than SCC made with natural sand. The study’s final findings, that emphasize the beneficial impacts of manufactured sand on SCC’s overall compressive strength characteristics, provide crucial data for enhancing concrete mix design. For the purpose of developing M sand, rocks are crushed to a similar size and form as natural sand or N-sand. The possible use of M-sand in SCC has been addressed in this paper. In this study, an effort has been made to analyze the potential use of M-sand in SCC. Self-Compacting Concrete (SCC) is a revolutionary concrete that allows for compaction and placement without the requirement for vibration. It may flow under its own weight even in the centre of dense reinforcement, entirely covering formwork and achieving full compaction. An attempt has been made to compare the characteristics of M35 self-compacting concrete in each its fresh and hardened states, substituting manufactured sand for river sand.
