A study of compressive strength of concrete by using sugarcane baggase ash

Abstract

Ordinary Portland cement (OPC) is widely as a construction material in the entire world. Since silica and lime being the basic components of the ordinary Portland cement therefore many industrial waste materials comprising of these elements are used as supplementary product in OPC. Sugarcane Bagasse ash is one such material which has high silica (SiO2) content that results in formation of C-S-H bond when operated with free lime. The basic idea behind the utilization of industrial waste is to reduce its abundance in nature and also to minimize the cost of concrete. The present study focusses on making a sustainable concrete and assessing its performance by using sugarcane baggase ash (SCBA) as replacement of cement with different percentages (0%,5%, 10%, 15%, and 20%). For the same M25 & M30 grade of concrete with water cement ratio of 0.45 was prepared by using this composition cube casted for testing purpose. The curing of these specimen was done in different environments and the strength was analyzed at various concrete ages i.e. 7, 28, 56, and 90 days. The study provided the evidence that utilization of SCBA as replacement with cement is highly advantageous up to an optimal limit without causing any reduction in strength. In addition, it revealed that SCBA concrete performs better when subjected to aggressive environment as compared to OPC even at later stage.
