Experimental Investigation on Fibre Reinforced Concrete Using Waste Plastics and Different Mineral Admixtures

Abstract

Use of Fibre Reinforced Concrete (FRC) is one of the ways of overcoming the low tensile strength of concrete. Both organic and inorganic fibers can be made use in the production of FRC. On the other hand, the use of waste plastic is causing a serious environmental pollution since the plastic don't deteriorate. Such waste plastic can be reused in the form of fibres to produce waste plastic FRC. Further, flyash, microsilica and redmud are another industrial waste materials adding to environmental pollution. These waste materials are having cementatious properties and can be used along with waste plastic fibres in concrete to reduce their detrimental effect on mother earth. Therefore in this paper an attempt is made to assess the suitability of waste plastic FRC for construction purposes when different percentages of flyash, microsilica and redmud are introduced. Various strength properties such as Compression, Tension, Flexure and Impact are studied along with workability characteristics. Based on the obtained results the industrial wastes such as flyash, microsilica, redmud and also waste plastic fibres can be used in the production waste plastic fibre reinforced concrete composite material.
