A Study of strength of concrete by using sugarcane baggase ash

Abstract

-Ordinary Portland cement is widely as a construction material in the entire world. The
composition of ordinary Portland cement includes lime and silica as major components which when undergoes
hydration forms C-S-H bond which acts like a strong glue with other material. 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 SCBA as replacement of cement with different percentages (0%, 5%, 10%, 15%, and 20%). The
concrete prepared using this composition was casted into cubes and cylinder 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.
