Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Plastic shrinkage cracks are a major concern in concrete structures, arising from rapid moisture loss before the development of adequate tensile strength. These cracks compromise durability, increase permeability, and accelerate structural deterioration.

Size effect on the flexural behavior of UHPFRC beams and RC beams strengthened with UHPFRC
Revista IBRACON de Estruturas e MateriaisAbstract 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.

An Advanced Approach to Derive the Constitutive Law of Uhpfrc [PDF]
Architecture, Civil Engineering, Environment, 2018 Abstract More than 200 specimens were tested in a comprehensive experimental campaign using ultra-high performance concrete with a mean compressive strength between 150 and 210 MPa and with different amounts of steel fibre reinforcement (0%, 1% and 2% by volume) from the first 2 days to 1.5 years after casting.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.To reveal the initiation and propagation mechanism of cracks at the precast–cast‐in‐place concrete interface of bridges in high‐temperature environments, an analytical model of interfacial cracks considering the thermo‐mechanical coupling effect is established based on linear elastic fracture mechanics.
