experimental investigation on the use of sugarcane bagasse ash and granite waste as fine aggregate in concrete

Abstract

Concrete is the most widely used construction material. Traditionally concrete is newlinemade up of cement as binder, river sand as fine aggregate, crushed stone aggregate as newlinecoarse aggregate. Unrestricted use of the natural resources in concrete making newlineresulted in their depletion at an alarming rate. Hence an attempt is made to perceive newlinethe potential use of industrial waste materials as fine aggregate in concrete. Granite newlineWaste (GW) is a waste material obtained from granite processing industries and newlineSugarcane Bagasse Ash (SCBA) is amply available in sugar industries as waste newlinematerial. newlineFirstly, the characterization of the industrial waste material is conducted to compare newlinethe properties with the natural river sand. It is understood that the sugarcane bagasse newlineash and granite waste has the filler property hence, comparable to the natural river newlinesand. To determine the optimum replacement percentage of the combined sugarcane newlinebagasse ash and granite waste as fine aggregate in concrete was determined based on newlinethe modified Andreassen grading curve derived by Funk and Dinger using a software newlinetool called EMMA (Elkem material mix analyzer) developed by ELKEM. The newlinepercentage replacement of fine aggregate is the sum of Sugarcane bagasse ash newline(27.5% of cement) and granite waste (9% of river sand) with total fine aggregate. It is newlineobserved that to obtain a dense mixture the required quantity of the material is newlinecalculated based on the size of the particle. newlineIn the second part of the investigation, the fresh and hardened property of the newlineconcrete made using sugarcane bagasse ash and granite waste as fine aggregate newline(BAGW) was compared with the conventional concrete. The test results indicated iv newlinethat the workability of BAGW concrete is less compared to the conventional concrete newlinetherefore superplasticizer is used. The strength properties of BAGW concrete are newlinemore comparable to that of conventional concrete.
