Study of the Mechanical and Durability Properties of Concrete Replacement of Cement by Sugarcane Baggase Ash

Abstract

Sugarcane is one of the major crops grown in over 110 countries and its total production is over 1500 million tons. In India sugarcane production is over 300 million tons per year that cause about 10 million tons of sugarcane bagasse ash as an un-utilized and waste material. After the extraction of all economical sugar from sugarcane, about 40-45% fibrous residue is obtained, which is reused in the same industry as fuel in boilers for power generation leaving behind 8-10 % ash as waste, known as sugarcane Bagasse ash (SCBA). The natural, bio-degradable features and chemical constituents of the sugarcane Bagasse (SCB) have been attracting attention as a highly potential and versatile ingredient in composite materials. Eco-friendly and low cost considerations have set the momentum for material science researchers to identify green materials that give low pollutant indexes. The study of cement replacement by sugarcane Bagasse ash (SCBA) in industrial scale aiming to reduce the CO2 emissions into the atmosphere. The utilization of waste materials in concrete manufacture provides a satisfactory solution to some of the environmental concerns and problems associated with waste management. Agro wastes such as rice husk ash, wheat straw ash, hazel nutshell and sugarcane bagasse ash are used as pozzolanic materials for the development of blended cements. Under this project PPC is partially replaced with finely ground Bagasse ash to make concrete. Cement is replaced with 0%, 5%, 10%, 15% and 20% of SCBA respectively and mechanical properties of concrete like Compressive Strength, Split Tensile Strength and flexural strength are determined at the age of 7 days, 14 days and 28 days. Also durability studies of concrete are performed with exposure to acid attack and sulphate attack
