effects on durability of concrete by using manufactured sand

Effect of granite dust on mechanical and some durability Experimental Investigation of the Effect of Manufactured

Apr 15 32 To make full use of it such granite dust was herein mixed into manufactured sand concrete as supplementary cementitious materials to replace fly ash in different proportions The mechanical and some durability properties of these concretes were studiedusing conventional natural and manufactured fine aggregates including granulated slag it is possible to produce concrete with good workability and compressive strengths in the range of 130 160 MPa without the need for complex mixing or curing regim Although research on different RS replacements such as manufactured sand RS 12
