Abstract

Many studies have been conducted with fibers of different types and shapes to increase the technical properties of concrete. Generally, steel fiber has been preferred in the places where the mechanical properties of concrete have priority in recent years. In this study, 2 different steel fiber types (Z, C shaped) and 80/60 steel fiber, which are formed by us, were used in the ratios of cement weights at 0.0, 0.10, 0.15 and 0.20. While the amount of air content and the workability of the steel fibers of these different shapes added in fresh concrete were observed; In hardened concrete, its effects on compressive strength, flexural strength and abrasion resistance were investigated. The shape and ratio of the fiber have been shown to be effective on fresh and hardened concrete properties. The optimum feature in fresh and hardened concrete has been achieved by using 10% of 80/60 fiber.
