Dec 16, 2017· Characteristics of MSand as a Partial Replacement with Fine Aggregate in Mix Design. Abstract: There is a great demand of both coarse fine aggregates for the construction of infrastructural facilities, rather than using a conventional river sand as a fine aggregate in concrete mix as one of the construction material which has led to the scarcity of the material .
In this experimental investigation, the strength characteristics of concrete is calculated using Msand for the three grades of concrete M30,M40 and Msand is partially and fully replaced for fine aggregate. For the present investigation, concrete cubes, cylinders and beams were casted and tested after 28 days of curing.
