Utilization of Bagasse Ash in Concrete and Curing it by Treated Hospital Wastewater
Abstract
This study examined the potential use of sugarcane bagasse ash as a partial cement replacement material and treated domestic wastewater was made for the mixing and curing of concrete. The bagasse ash was collected from the Malaprabha sugar industry, Belagavi, and the treated wastewater was collected from Dr. Prabhakar Kore Hospital & MRC, Belagavi. The work involved the design of M20 grade concrete with w/c ratio of 0.40 and also chemical admixture was made used. The study evaluated the slump, compressive strength, and split tensile strength of concrete with different cement replacement ratios. An equal number of cubes and cylinders were casted and were cured in both tap water and treated wastewater separately for a curing period of 28 days and 56 days. The compressive and tensile strength results were obtained after 28 days of curing period for cubes and cylinders. Results show that replacement of cement with bagasse ash and curing them under treated wastewater obtained good results, which supports waste minimization and utilization. The blended concrete compressive strength results also indicate that the easing of sulphate attack will be drastically reduced when cured under treated wastewater.
