The Effect on Concrete Strength by Partially Replacing Cement with Brick Kiln Dust and Fly Ash

Abstract

AbstractNowadays, in the area of construction, cement concrete is playing a vital role for the formation of any kind of structural component or element, related to beam, column, slab, bridge, girder, or even in the rigid pavement also. For concrete production, cement is the most important binding material, as its property is to bind both the coarse aggregate and fine aggregate when mixed with water. The title of the paper denotes that the terms brick kiln dust (BKD) and fly ash (FA) are the waste products, having some binding properties when mixed with water. The researcher’s attempt is to show how OPC 43 grade cement is partially substituted with FA and BKD combined together in the percentage of 0%, 10%, 20%, 30% and 40% during the production of concrete of design mix M25, and also to determine the compressive strength as per Indian Standards. The result obtained after experimental investigation shows that the FA and BKD can be used in the production of concrete with an aim to reducing both global warming and cost of the cement concrete.KeywordsBrick kiln dustCoarse aggregateConcreteFine aggregateFly ashOPC 43 grade cement
