Effect of Use Sugarcane Bagasse Ash and Rubber Tyre as A Partial Replacement of Cement and Coarse Aggregate in Concrete

Abstract

Abstract: Recycling and usage of waste products can be a viable option in the waste management of many materials. The present study focuses on the utilization of Sugarcane Bagasse Ash(SCBA) as replacement material for cement and rubber tyre as replacement material for coarse aggregate in concrete production. Noting the increasing volumes and difficulty in the disposal of wastes from rubber tyres and SCBA, this paper discusses test results of use of SCBA and recycled tyres in concrete for possible application in the construction industry. Sugarcane Bagasse ash contains high amorphous silica content and aluminium ion. For experimental investigations, Sugarcane bagasse ash and its chemical properties are obtained from Sakthi sugars private ltd, Aapakoodal, Tamilnadu. Ordinary Portland cement was partly replaced by sugarcane bagasse ash in the ratio of 0%, 10%, 20% and 30% by weight. The results indicate that inclusion of Sugarcane Bagasse Ash in concrete up to 20% level significantly enhanced the strength of concrete. In 2008, around one billion end-of-life tyres (ELTs) were being produced globally each year. As a possible means of disposing the tyres, it is proposed to use rubber tyres as coarse aggregate in concrete. Tyres cut into pieces with maximum size of 20 mm to use as coarse aggregate.It were used in the replacement of 15% of the normal gravel. Grade of concrete used in this paper is M30.Compressive strength, splitting tensile, and flexural strength tests were conducted according to the various BS codes. This paper also demonstrated the variation in the compressive strength of the non-conventional concrete when the BS and ACI methods are used in the design of the mix.
