Compressive and Flexural Behaviour of Mortar Infiltrated Fiber Concrete Using Different Types of Fibres

Abstract

This paper examined the comparison between the mechanical properties of mortar infiltrated fibers concrete with two types of fibers (End hooked steel fiber and Synthetic fiber) with varying fibre volume. The difference in properties of the concrete with steel fiber, concrete without fiber and concrete with Synthetic fiber was determined. Compressive strength and flexural strength (Modulus of rupture) of concrete were determined. The concrete mixing containing [0% control, (2,4 and 6%)] fibre volume of (End Hooked) and Synthetic fiber were used for compressive and flexural strengths tests. Steel fiber was (30 mm) in length and (0.5mm) diameter, while Synthetic fiber was (60mm) in length and (0.84mm) diameter. the concrete cube used was (100×100mm) for compressive strength test, also beam used for flexural strength test with dimensions (400×100×100mm). The results showed that with increasing volumetric ratio of fiber, the compressive strength and flexural strength increase. The compressive strength and flexural strength of hooked fiber have a much higher extent increasing than that of synthetic fiber.
