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 ...

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,

Axial tensile strengths of UHPC and UHPFRC
IOP Conference Series: Materials Science and Engineering, 2019 Abstract UHPC and UHPFRC are remarkable materials which have properties with significant advantages. In addition to high compressive strength, they have higher tensile strength than conventional concrete. To study the tensile strength of UHPC and UHPFRC, a series of experimental programs have been developed at Kassel University.

Flexural quasi-static behaviour of UHPFRC and R-UHPFRC circular slab specimens
, 2017 This paper investigates experimentally and numerically the biaxial flexural behaviour of thin circular slab specimens made of Ultra High Performance Fibre Reinforced Cementitious Composite (UHPFRC). The circular slab specimens represent an external tensile reinforcement layer for reinforced concrete (RC) slabs or a new thin slab element, for the ...

Experimental Investigation of Mechanical Properties of UHPFRC
Procedia Engineering, 2013 AbstractThis paper describes experimental investigations of various mechanical properties of Ultra High Performance Fiber Reinforced Concrete (UHPFRC). The UHPFRC is a modern cementitious composite containing a large amount of cement, both reactive and nonreactive very fine particles, chemical admixtures and short high strength steel fibers.
