In this paper an attempt has been made to study the effect of addition of Microsilica and replacement cement by Microsilica in different percentages on the properties of workability and strength characteristics of waste plastic fibre reinforced concrete. The strength characteristics viz., compressive strength, tensile strength, flexural strength, impact strength and workability characteristics are found for waste plastic fibre reinforced concrete, when Microsilica was added and replaced by cement in different percentages viz, 0%, 2%, 4%, 6%, 8%, 10% and 12% respectively by weight of cement. Waste plastic fibres having an aspect ratio 50 (thickness = 1mm, length = 50mm and breadth = 5mm) were added at the rate of 0.5% (by volume fraction). The results show that upto 10% of Microsilica can be added and 8% of Microsilica can be replaced by weight of cement into waste plastic fibre reinforced concrete, without adversely affecting the compressive strength and with advantage in other strength properties.
