DURABILITY ANALYSIS OF BLENDED CONCRETE AND BEHAVIOUR AT ELEVATED TEMPERATURE

Abstract

Rubber & Sugarcane Bagasse Ash are few of the leading waste materials that needs to be recycled. Sugarcane Bagasse is being recycled into Plates & other utensils that are being used in many big brand restaurants but there is still a very huge gap between the waste disposal as well as the recycling. Not to count the Ash which is the by-product of the burning of Sugarcane Bagasse in the Sugar Industries which are either dumped in an open fil or in a pond, which in turn pollutes the air as well as the water. Sugarcane Bagasse Ash, has good cementitious properties which can be used in the Construction Industry to replace the cement & reduce the pollution caused by it to some extent. Waste Tyre Rubber is another material that is being used in this research. Out of 1.5 billion waste Tyres that are generated worldwide, about 6% of them are generated in India only. So, there is a gap in recycling here and there is a opportunity to benefit from it and use it as a replacement of Aggregates in the Concrete. Rubber has good Energy Absorption capacity, as well as high durability. In this research the durability properties as well as the compressive strength of the concrete that is made by the replacement of Sugarcane Bagasse Ash with Cement & Waste Tyre Rubber Crumbs with Fine Aggregates has been examined. For this, 15%, 20% & 25% replacement of SCBA & 10%, 20% & 30% replacement of Waste Tyre Rubber has been considered. Various tests like Mass Evaluation, Energy Absorption, Compressive Strength, Water Absorption, Chloride Attack, Carbonation, Sulphate Attack and Behaviour at Elevated Temperature on Hardened State of Concrete and Slump Test on Fresh Concrete hence achieving the optimum percentage replacement iv of both the materials and then the same tests were performed on the concrete made with the optimum replacement value of the materials replaced in the concrete. From the research, it is concluded that the 20% Sugarcane Bagasse Ash & 20% Waste Tyre Rubber are the optimum percentage of replacement value for required durability of the concrete.
