Rebar-reinforced coarse aggregate ultra-high-performance concrete (R-CA-UHPC) has been used in the construction of new structures and strengthening of deteriorated aged infrastructures, and it inevitably sustains tension. To study the tensile behavior of R-CA-UHPC members, axial tensile tests for dog-bone-shaped specimens were designed and...

To establish the tensile constitutive model of ultra-high performance concrete containing coarse aggregate (CA-UHPC), monotonic and cyclic uniaxial tensile tests for CA-UHPC with fiber volume fractions of 2.5% and 2.0% were conducted. Test results showed that CA-UHPC exhibits approximately linear stress-strain relation up to the tensile strength...

To investigate the fatigue performance and fatigue damage process of the Orthotropic Steel Deck (OSD) - Ultra-High Performance Concrete (UHPC) composite bridge deck, a two-span continuous full-scale specimen was designed and tested under cyclic loading. Test results showed that the fatigue cracks firstly initiated near the lower part of the weld...

The development of numerical simulation for Ultra-high-performance concrete (UHPC) and Ultra-high-performance fiber-reinforced concretes (UHPFRC) is fundamental for the design and construction of related structures. The simplified engineering stress-strain relationship and the input values are necessary in the finite element modeling. Four...

Ultra-high performance concrete (UHPC) is an innovative cement-based composite with high mechanical performance under tensile and compressive loads, extremely low permeability, and excellent durability. Because of these features, UHPC has the potential to contribute to the development of new architectural perspectives and structural systems...

Ultra-high performance concrete (UHPC), which typically contains extremely high superplasticizer amount, tends to render a special type of dense surface layer, especially under drying conditions. Even if the inner side of fresh UHPC is still in a flowable nature, the top surface of the concrete which is exposed to ambient conditions renders a...

Most of the bridges and viaducts in the Netherlands were built in the sixties and seventies of the last century, and an increasing number of them will have to be replaced due to technical or functional reasons. The Netherlands is not an exception, many industrialized countries will face a similar replacement task in the near future. With the...

Rheology and shrinkage are the key features that should be controlled to perform a successful casting process and obtain a durable ultra-high performance concrete (UHPC). It is anticipated that cast-in-situ applications of UHPC will increase in the near future, so the studies on early-age properties of UHPC have come into prominence. However,...

The distinct feature of UHPC is the tensile strain hardening phenomena and high compressive strength. We can either use this potential as an additional safety margin in structures or design structures with no passive reinforcement.<br/>The advancements in active structural health monitoring devices have opened further possibilities to validate...

Bridges are a crucial part of the dense Dutch highway network. Almost 50% of the current bridges are built between 1960 and 1980 for an intended service life of 50 years and thus they might reach the end of their lifetime in the near future. This strongly indicates that a large challenge can be expected regarding infrastructural replacement.<br/...

Advanced Cementitious Materials (ACM’s) are products with materials found in conventional concrete (cement, silica fume, sand, superplasticizer, and water) plus distinctive materials like fibers (steel, carbon) and quartz. The superiority of ACM’s in terms of strength, ductility, and durability marks it as high potential replacement of...

A majority of the bridges and viaducts in the Netherlands were built in the sixties and seventies of the last century and many of them will need to be replaced in the near future due to technical or functional reasons. This is a replacement issue, faced by many countries worldwide. But what about the concrete structures? Should we replace them...

Incremental bridge launching is one of the many ways in which a bridge can be constructed. In The Netherlands this method is not often used. This may be explained by the fact, that there are not many suitable locations for application of this method. Incremental bridge launching is profitable for long bridges and can only be used for straight...

A study has been performed in the application of Ultra High Performance Concrete (UHPC) in the new Leiden Bridge. It has been compared with normal strength and high performance concrete. The goal was to investigate if UHPC could be used as a serious alternative next to other types of concrete for a design in bridges. The research showed that...

Material properties of concrete have developed rapidly in the past fifteen years. With the advent of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) a new material has emerged which is; much stronger, stiffer and durable than conventional concrete. Nonetheless despite these promising developments and due the high material costs UHPFRC...

The first part of this paper provided a brief overview of how UHPFRC is made and why it can achieve such high mechanical properties. At this moment UHPC can easily achieve compressive strengths of 200 MPa, which is about seven times higher than ordinary concrete. However the tensile strength remains normative for structural design. The flexural...

In some large cities, the infrastructure is elevated high above the ground. An elevated metro system has the advantage that its construction is cheaper compared to an underground metro system. The construction time is relative limited and the physical barrier is small. The large elevation has a positive influence on the visual hindrance of an...

Recently, a number of high strength and ultra high strength steel fibre concretes have been developed. Since these materials seem very suitable for structures that might be prone to fatigue failure, such as bridge decks, the understanding of the static and fatigue bending behaviour is vital. In order to evaluate the bending behaviour of high and...
