The main objective of this experimental investigation is to find out the effect of replacement of cement by Microsilica on the workability and strength characteristics of waste plastic fibre reinforced concrete (WPFRC). The strength characteristics viz., compressive strength, tensile strength, flexural strength, impact strength and workability characteristics are found for WPFRC when Microsilica-600 is replaced 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 = 30mm and breadth = 5mm) were added at the rate of 0.5% (by volume fraction). The results show that up to 8% Microsilica-600 can be replaced by weight of cement into WPFRC, without adversely affecting the compressive strength and with advantage in other strength properties.
