Effect of Addition of Flyash on the Properties of Waste Plastic Fibre Reinforced Concrete-an Experimental Investigation

The fibre reinforced concrete, which is defined as a composite material consisting of a material of cement mortar or concrete and discontinues discrete, uniformly distributed fibres has gained a wide popularity in the construction industry. The introduction of fibres into the concrete induces many desirable properties to the concrete and such concrete has wide varieties of applications in the field of civil engineering. Many types of fibres like steel, carbon, GI, glass, asbestos fibres can be used for the production of fibre reinforced concrete. The plastic is causing an environmental pollution. The plastic is a non-biodegradable material. It do not undergo decay. To destroy this plastic, if it is burnt, it adds to air pollution by releasing many toxic gases. Thus, for environmentalists, the plastic has become a big headache. Flyash is another industrial waste which is causing environmental pollution. The water in which flysah falls becomes unfit for drinking. The land on which it falls becomes infertile. The air becomes polluted since it spreads into atmosphere and causes lung problems. In this paper an attempts has been made to study the properties of fibre reinforced concrete produced from waste plastic fibres and flyash which are the two environmental pollutions. The strength characteristics of waste plastic fibre reinforced concrete like compressive strength, tensile strength, flexural strength and impact strength are found when the flyash is added in different percentages like 0%, 30%, 50%, 70%, 90%, and 110%. Also the workability characteristic of waste plastic fibre reinforced concrete with flyash is studied.
