Abstract

AbstractIn this paper, an endeavour has been made to swot the effect of micro silica (MS) or silicafume with partial replacement of cement (i.e., 0, 5, 10, 15, 20 and 25%) and also with fullreplacement of natural sand by crusher wash sand (CWS) on strength and durabilityproperties for high performance concrete (HPC) of M50 grade with water cement ratio as0.30. Test results indicate that, the use of MS has improved the property of concrete in bothfresh and hardened state. From the results, it is also understood that 25% replacement ofcement by MS are showing the better result in all aspects. Finally, the investigation revealedthat use of one of such waste materials as MS, which is a waste material obtained from alloyindustries can be used for partial replacement of cement, which leads to economy and inaddition by utilizing the industrial wastes in the useful manner. The environment pollution isalso reduced to great extent, which leads to sustainable development.Keywords: High performance concrete, micro silica, silica fume, crusher wash sandCite this ArticleMuthumari G, Niraikula Sekaran K.Experimental Study on Micro SilicaAmalgamated High Performance Concrete.Recent Trends in Civil Engineering &Technology. 2017; 7(3): 46–52p.
