Combined use of Stone Dust as Partial Replacement of Sand and Glass Powder as Cement

Abstract

In this research we analyze the strength of concrete made with using locally available fly ash based Cement by using two waste materials one is Glass Powder and Other is Stone dust. The Glass Powder is used as 20% replacement of the cement and Stone Dust as the partial replacement of Fine Aggregate from 0%, 10%, 20%, 30% and 40%. The grade of the concrete here is M25 and M30 grade. Slump Test was carried out for the fresh concrete whereas Compressive Strength, Flexure Strength and Split Tensile Tests were carried for the Hardened concrete. All tests are done at 7, 14, 28, and 56 days with 0 to 40% replacement of sand at an interval of 10%. Again above tests are carried out with 20% replacement of cement by glass powder. It is observed that the glass powder improve the strength and stone dust can be used as sand. This is great saving in costly material.
