Difference Between M sand and River sand. Concrete with m sand has very poor permeability as compared to river sand. But when river sand is used in concrete the permeability of concrete is less poor as compared to river sand. It has more water absorption 2 to 4 %. Whereas water absorption of river sand is less 1.5 to 3%.
