EXPERIMENTAL ANALYSIS OF CONCRETE WITH RICH MINERAL SILICA ADDITIVES

Silica mineral (Ecosand) being a waste material generated from manufacture of cement fromindustry. It can be used to increases efficiency in concrete. An experimental study has been done toachieve high strength concrete using silica mineral (Ecosand) from manufacture of cement as thepartial replacement of natural sand (upto 50%) in concrete and studied its mechanicalproperties .Experimental results are also shows that the compressive strength, flexural strength,splitting tensile strength and structural behaviour of beam of silica mineral (Ecosand) and naturalsand such that the combination of two aggregate can be increased efficiency in concrete. Thecombined grading of fine aggregate of tested results shows closest to zone III and zone IV
