An Experimental Investigation on Effect of High strength Concrete Using manufacturing Sand. ... concrete as a viable alternative to natural sand for the High Performance Concrete in the ...
supply of high quality aggregate for concrete, both coarse and fine, are of extreme importance. The growing shortage and price rise of the natural sand is also a question that a construction industry shall think about. Now looking for viable alternatives to natural sand is a must and not a necessity.
Manufactured Sand vs. Natural Sand. The choice of fine aggregate, whether it is manufactured or natural sand, can greatly impact the fresh concrete properties of a mixture such as the workability, pumpability, and finishability. Natural sand has an ideal shape for use as fine aggregate in concrete. The natural sand particles are wellrounded ...
of High strength concrete to develop the compressive strength of concrete by replacing Natural sand into Manufacture sand and using admixture. To examine the workability of manufactured sand and using admixture in concrete. To investigate the performance of this concrete terms of its compressive strength and split tensile strength.
Jun 11, 2010· High performance concrete is a concrete mixture, which possess high durability and high strength when compared to conventional concrete. This concrete contains one or more of cementious materials such as fly ash, Silica fume or ground granulated blast furnace slag and usually a super plasticizer.
The targeted areas were asphalt, pavement performance, concrete structures, and highway operations. The Center for Building Technology at NIST is also conducting research to improve concrete performance. The projects include several that are developing new methods of field testing concrete.
