Research on Flexural Properties and Flexural Toughness Evaluation Method of Steel Fiber Reinforced Cementitious Composites under Polar Low Temperatures

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
In this research, five groups of steel fiber reinforced cementitious composite (SFRCC) with different fiber volume content (0%, 0.5%, 1.0% 1.5%, and 2.0%) were designed to perform four‐point flexural tests on beam specimens to study the effects of polar temperature (20, 0, −25, −50, −75, and −100°C) and fiber volume content on the flexural properties ...

Performance Evaluation of Hybrid Fiber‐Reinforced Inorganic Mortar for Textile‐Reinforced Mortar Applications

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
The need to improve existing structures has led to extensive research on strengthening techniques. Textile‐reinforced mortar (TRM) systems, which involve the integration of high‐strength fibers with inorganic matrix, have emerged as a highly promising and viable alternative.

Size effect on the flexural behavior of UHPFRC beams and RC beams strengthened with UHPFRC

Revista IBRACON de Estruturas e Materiais
Abstract The presence of fibers in Ultra-High-Performance Fiber Reinforced Concrete (UHPFRC) considerably affects the mechanical behavior of structural elements constructed from this material. While the flexural strength of traditional reinforced concrete beams is size-independent, this is not the case for UHPFRC.

Evaluation of UHPFRC activation energy using empirical models [PDF]

, 2018
The influence of thermal curing on the evolution of the material properties and the UHPFRC behaviour was investigated. Tests results showed a beneficial effect of a high temperature curing on the early age material properties due to the thermo-activation
