Experimental Investigation on Steel Fibre Reinforced Concrete Made Pet Waste Pet Waste with Partial Replacement of Coarse Aggregate

Concrete is a composite material consisting of mortar and coarse aggregate.An existing problem of concrete is formation of crack.In this study feel fibres are added in concrete to control the concrete 1,1.5,2%of steel fibre is added in concrete, which is the efficient percentage of addition in reinforced concrete. In addition to that to overcome the scarcity of conventional coarse aggregate now-a-days usage of (PET)poly ethylene terephthylate is highly recommended. A conventional method is proposed by using (PET)poly ethylene terephthlate as partial replacement of coarse aggregate to its weight with addition of 1,1.5,2% of steel fibre to the volume of concrete in specimen. Cube of size 150 x 150 x 150 mm is casted and tested, which is designed according to Indian standard codes. The flexural properties of the cube are compared between control specimen and 5%, 10%,15% and 20% partially replaced (PET )poly ethylene terephthalate as coarse aggregate specimens INTRODUCTION: Concrete is known as a brittle material with low bearing capacity for deformation under tensile stress. The development of these tensile stresses are mechanical loading, harmful reactions and environmental loading. Cracks which affect the structural performance of the concrete are caused mainly due to this stress. In order to control the formation of and development of these cracking fibre are introduced in concrete. Use of steel fibre concrete has steadily increased during the past years. Considerable developments have taken place in the field of steel fibre reinforced concrete. The current field of application of steel fibre reinforced concrete in highway and airfield pavement, bridge decks, hydraulic structures, tunnel linings etc. There are many research works done on adding steel fibre in concrete to increase the structural properties of the concrete. It is proved that addition of steel fibres in concrete increas-es many of the engineering properties in mortar and con-crete. Flexural strength, fatigue strength, tensile strength and the ability to resist cracking and spalling are also en-hanced. The most suitable volume fraction values for concrete mix-es are 0.5% to 2.5% by volume of concrete. The most opti-mum percentage of mix to be added in concrete is 1% as addition more amount of steel fibre increases the efficiency but the workability of concrete is reduced. Among different waste fractions, plastic waste deserves special attention on account non-biodegradable property which is creating a lot of problems in the environment. In India approximately 40 million tons of solid waste is produced annually. This is increasing at a rate of 1.5 to 2% every year. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. The PET bottles cannot be disposed of by dumping or burning, as they produce uncontrolled fire or contaminate the soil and vegetation. Considerable researches and studies were carried out in some countries like USA and UK on this topic. However, there have been very limited studies in India on plastics in Concrete. Hence an attempt on the utilization of waste Poly-ethylene Terephthalate (PET) waste and steel fibre granules[1] as fine aggregate is done and its mechanical behaviour is investigated. ABOUT THE PROJECT A. Objectives of the Proposed Project The main objectives of this research proposal are to evaluate the possibility of using granulated plastic waste materials. The following were also proposed. As partial substitute for the coarse aggregate in concrete composites To investigate the structural behavior of such replaced concrete components To investigate the mechanical behavior of the components by using fibers. To determine the percentage of plastic fibre which gives more strength when compared to control concrete. B. Importance of the present project The problem of disposing and managing solid waste materials in all countries has become one of the major environmental, economical, and social issues.
