Effect of curing age on pullout behavior of aligned and inclined steel fibers embedded in UHPFRC

Pablo Augusto Krahl et al.

Summary: In UHPFRC, the bond strength of fibers with different inclinations increases with time, with a smaller growth for 45 degrees and a larger growth for 30 degrees. The significant increase for fibers inclined at 30 degrees is mainly attributed to the increased friction at the interface due to the snubbing effect.

A multi-index synthetical evaluation of pull-out behaviors of hooked-end steel fiber embedded in mortars

Xinxin Ding et al.

Summary: The study focuses on evaluating the bond performance of steel fiber in concrete matrix with a multi-index synthetic evaluation, linking bond mechanisms to the load-slip curve characteristics of hooked-end steel fiber. Results show that factors like mortar strength and type of sand can affect the bond performance of steel fiber, and the use of hooked-end steel fiber with a specific tensile strength matched well with certain compressive strength of mortar. The hooked-end plays a controlling role in providing reliable bond performance, and the rational length of hooked-end steel fiber can be optimized based on bond requirements.

Contribution of fiber alignment on flexural properties of UHPC and prediction using the Composite Theory

Huanghuang Huang et al.

Summary: This study investigates the impact of fiber alignment on the flexural properties of UHPC with different steel fiber lengths and volumes. The flow-induced casting method significantly enhances fiber orientation, leading to increased flexural strength and toughness. Increases in fiber length, volume, and orientation all result in higher flexural-to-tensile strength ratios of UHPC. The Composite Theory can be used to predict the flexural strength of UHPC with a maximum spread of 15%.
