M-sand is also called artificial sand or crushed sand, prepared by crushing rocks, stones, or larger aggregates into small particles in the quarry. The study is aimed at the complete replacement of conventional material like river sand used as fine aggregate. By using M-sand (manufactured sand/crushed sand). M-sand here acts as a fine aggregate in the cement concrete. Natural fine aggregate is replaced by M-sand to complete mix proportion in the concrete. M-sand shares similar properties as conventional Fine Aggregates and gives good split tensile and compressive strength to the concrete. The results are compared with the control mix of design mix M30. Complete replacement of fine aggregate with manufactured sand concrete makes the construction cost controlled. Compressive strength is the most important property of concrete it is also increasing. Complete replacement of fine aggregate with crushed sand production of concrete increasing. It is dust-free in M-sand which is a good sign to do the replacement. Environment preservation and natural resources conservation is the soul of country development. The application of crushed sand mix for residential building structural members such as column, beam, slab, and foundation and plastering are also elicited. The study brings out the fact that it is also more economical than the typical cement concrete. The findings of this research call for the safe use of manufactured sand. Economical concrete mix is a very useful construction material, which offers a range of economic, technical, and environmental enhancing and preserving advantages and is destined to become a dominant material for construction in the new era.
