Performance Evaluation of Self-Compacting Concrete Using Bagasse Ash and Granite as Partial Replacement of Cement and Sand
Main Article Content
Abstract
Concrete is a broadly used man-made construction material, consuming cement and natural aggregates. World is facing key environmental problems as industries produce large amount of wastes and some of them like cement industry, emit harmful gases such as carbon dioxide. Waste Bagasse ash (BA) is produced in sugar industry while waste marble and granite are generated during their crushing and cutting. As there are no proper disposal and control facilities available for these industrial wastes and end in land fill, these waste materials may be utilized in concrete as cement and aggregate substituents. Key objective of this study was to evaluate the effects of BA and granite sand (GS) as a partial substitute of cement and natural sand in self-compacting concrete (SCC). Reference mix was finalized for SCC using waste marble powder as filler material. 10 %, 15 %, and 20 % cement by mass was replaced by BA and GS as a substitute for natural sand at 10 %, 20 % and 30 % by mass. Workability, density and air content were tested for fresh concrete. Also, mechanical properties i.e. compressive, splitting tensile, flexural strength and modulus of elasticity were tested. Results indicated declining trend in the workability of concrete when BA and GA were incorporated into SCC while the mechanical properties improved. Thus, SCC with better mechanical properties can be produced by utilizing industrial waste materials as fractional substitutes of cement and sand which in turns will reduce negative impact on environment and utilization of natural materials in concrete production.
