Fracture toughness of ultra high performance concrete
In this study, fracture properties of Ultra-High Performance Concrete (UHPC), and High Performance Concrete (HPC) are presented. The average compressive strengths of UHPC and HPC used in the tests were 141 MPa, and 55 MPa respectively. Formulation and processing of the mixes and test specimens are …

Evaluation of Elastic-Plastic and Damage Models for Ultra High Performance Concrete (UHPC)
<p>Ultra-high performance concrete (UHPC) has been developed in recent decades as a new class of concrete which exhibits increased strength, durability and long-term stability when compared with normal strength concrete (NSC) and high performance concrete (HPC). While extensive research has …

Low-Shrinkage Fiber-Reinforced Concrete for Infrastructure Construction and Rehabilitation
… study is to develop two classes of low-shrinkage high-performance concrete (HPC): fiber-reinforced super workable concrete (FR-SWC) for infrastructure construction and fiber-reinforced self-consolidating concrete (FR-SCC) for repair applications. HPC with excess content of shrinkage mitigation …

Interface durability of externally bonded GFRP to normal and high-performance concrete
… used for seismic retrofit and rehabilitation of concrete structures. Glass fibers exhibit high strength to weight ratio and low cost in comparison to carbon and aramid fibers. However, previous studies have shown that glass fibers are vulnerable to attack caused by harsh environmental weathering …

Investigating repair mortars containing superabsorbent polymers as a method of internal curing to improve concrete patch repair performance
Concrete structures are designed with a specific service life in mind and deteriorate over time due to their exposure to environmental conditions. In order to increase the service life of concrete structures, they can sometimes be rehabilitated and repaired using concrete overlays. However, …

High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties
Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. The criticism concerns issues as …

Early age creep and shrinkage of emerging concrete materials
Concrete pavements and structures are especially vulnerable to cracking at early age. The volumetric instability of concrete at early age is a frequent cause of cracking. The primary components of volume change are external drying shrinkage, autogenous shrinkage, and thermal dilation. When concrete …
