Abstract
The use of steel fiber in SCC is known as steel fiber reinforcement self-compacting concrete (SFRSCC). Since its development, steel fiber consists of various shapes such as straight, crimped, and hooked-end. The purpose of this research is to analyze the influence of shape variation and volume fraction (Vf) of hooked-end steel fibers to fresh and hardened properties of SFRSCC. Fresh concrete testing is done based on EFNARC standard such as Slump flow test, V-funnel test, and L-box test. Hardened concrete testing is done in the form of compressive strength and splitting tensile strength. The steel fiber used is a hooked-end type which consists of three types namely, 3D, 4D, and 5D with value of volume fraction (Vf) are 0.50%, 0.75%, and 1.00%. The results of this study were indicated the effect of volume fraction (Vf) increasing can decrease the workability of SFRSCC. Mix design SFRSCC in this research meets SF1 and SF 2 filling ability classes, Viscosity VS2, VF1 and VF 2 class, and passing ability PA 2 class. For mechanical properties obtained maximum compressive strength of 55.85 MPa with percentage increase of concrete without steel fiber equal to 32.66%, and maximum splitting tensile strength of 6.38 MPa with percentage increase of 82.81%. The maximum mechanical properties are obtained by volume fraction (Vf) = 1.00% and 5D type steel fiber.
