Rocket blast resistance of the fully demountable high performance FRC tongue and groove blocks

Structural Concrete, Volume 25, Issue 2, Page 826-849, April 2024.
Abstract Within the scope of this study, the design and testing of a fully demountable high‐performance fiber‐reinforced concrete (FRC) barriers with high resistance to sudden dynamic explosion and impact loadings is investigated. In order to solve such an engineering problem, a special FRC “tongue and groove” blocks are designed in a way that could be

Effects of thermal damage on physical properties and cracking behavior of ultrahigh-performance fiber-reinforced concrete

, 2016
International audienceIn this work, we study the impact of thermal damage on the physical and mechanical properties of ultrahigh-performance fiber-reinforced concrete (UHPFRC), especially on their cracking process under compressive loading. Four mixtures

The influence of granite cutting waste on the properties of ultra-high performance concrete [PDF]

, 2019
This study analyzes the effect of using waste by-products generated in the process of granite cutting as part of the granular structure of Ultra High Performance Concrete (UHPC). The manufactured concrete has a compressive strength greater than 115 MPa.

Shear bond between existing concrete and high‐strength fiber reinforced overlay: Influence of substrate strength and interface roughness

Structural Concrete, Volume 25, Issue 1, Page 526-536, February 2024.
Abstract Bonded concrete overlays are widely used for strengthening and repair of concrete members. The aim of a concrete repair is to restore the load‐carrying capacity and stiffness of a concrete member, and to extend the service life of a structure. The bond between substrate and overlay is one of the main factors concerning the serviceability of a ...

Improved static and impact properties of UHPFRC retrofitted with PU grout materials: Experiments and ML algorithms

Results in Engineering
This study addresses the inherent brittleness of ultra-high-performance fiber re-inforced concrete (UHPFRC) by introducing a U-shaped specimen and investigating the impact strength of U-shaped UHPFRC retrofitted with polyurethane (PU) grout overlays.

Experimental and theoretical analysis of cracking and tension stiffening in UHPFRC under high‐cycle fatigue

Structural Concrete, Volume 25, Issue 1, Page 379-402, February 2024.
Abstract Tension‐stiffening controls the serviceability behavior of concrete structures as it is responsible for crack formation and, consequently, the deflection of beams. In fiber reinforced concrete, such as ultra‐high performance fiber reinforced concrete (UHPFRC), fibers bridge cracks and thereby transfer tensile stresses across the cracked region,

New perspectives on carbon reinforced concrete structures—Why new composites need new design strategies

Civil Engineering Design, Volume 5, Issue 5-6, Page 67-94, January 2024.
Abstract In civil engineering, carbon is typically regarded as a modern material to serve as reinforcement in concrete structures. Compared to steel reinforcement, it features two substantial benefits: It is not sensitive to corrosion, and has an enormously increased tensile strength.

Dynamic Effects of Turbulent Crosswind on the Serviceability State of Vibrations of a Slender Arch Bridge Including Wind-Vehicle-Bridge Interaction [PDF]

, 2017
The use of high-performance materials in bridges is leading to structures that are more susceptible to wind- and traffic-induced vibrations due to the reduction in the weight and the increment of the slenderness in the deck.
