This paper investigates the effect of synthetic fibre and fly ash (FA) on post peak response and fracture properties of concrete. Polyvinyl alcohol (PVA) fibres were added as intrinsic reinforcement to concrete and30%of cementwas replaced with fly ash as an environmental friendly additive to reduce cement consumption. Samples were prepared abiding by relevant standards and tested accordingly. Limit of Proportionality (LOP) of the mentioned concretes has been assessed. Notched rectangular prisms have been tested to evaluate the residual flexural tensile strength and limit of proportionality of conventional and FA modified concrete as well as fibre reinforced concrete (FRC). Cylindrical samples have been tested to determine the compressive strength and indirect tensile strength of each concrete. Tests have been conducted at 28 days of ageing. Results gathered from different mix designs are compared to control and other mixes. © 2013 Taylor & Francis Group.
