It's great to see initiatives exploring alternatives to traditional construction materials like sand. The use of manufactured sand as a substitute for natural sand in concrete has gained attention due to concerns over the environmental impact of excessive sand mining from riverbeds. Manufactured sand is one among such materials to replace river sand, which can be used as an alternative fine aggregate in mortars and concretes. Manufactured sand is a term used for aggregate materials less than 4.75mm and which are processed from crushed rock or gravel. That's a commendable project focus. Too effectively study the influence of manufactured sand on the compressive strength and durability of concrete and assess its prospects as a replacement for natural sand in India, Initially, different natural and manufactured sand samples to be used in the concrete mixes were collected and their physical properties were studied. M50 grade concrete having three mix proportions for both natural and manufactured sand (i.e. 100% RS+0% MS; 50% RS+50%MS; and 0%RS+100%MS) were prepared for concrete using a water cement ratio of 0.36 and cement contents of 450 kg/m3. The properties of these mixes have then been assessed both at the fresh, hardened and durability state.
