Study on the Performance of Concrete Using Waste Glass and Sugarcane Bagasse Ash

Abstract

Abstract: During cement production, the emission of CO2 has significant impact on environment. Apart from this, the extraction of natural aggregates and generation of industrial, agricultural and domestic waste also leads to environment degradation. The use of these waste materials not only helps to reduce the use of natural resources also helps to mitigate the environment pollution. The basic objective of this research is to investigate the effect of Waste Glass (WG) as partial replacement of fine aggregates and Sugarcane Bagasse Ash (SCBA) as partial replacement of cement in concrete. This study primarily deals with the characteristics of concrete, including compressive strength, workability and thermal stability of all concrete mixes at elevated temperature. Twenty-five mixes of concrete were prepared at different replacement levels of WG (0%, 10%, 20%, 30% & 40%) with fine aggregates and SCBA(0%, 5%, 10%, 15% & 20%) with cement. The water/cement ratio in all the mixes was kept at 0.55. The workability of concrete was tested immediately after preparing the concrete whereas the compressive strength of concrete was tested after 14, 28 and 60 days of curing. Based on the test results, a combination of 10% WG and 10% SCBA is the most significant for high strength and economical concrete. This research also indicates that the contribution of WG and SCBA doesn’t change the thermal properties of concrete
