“…It consists of a p-shaped arch supporting a ribbed UHPFRC slab with a thickness of 30 mm, and transverse prestressing was provided by sheathed monostrands. With equivalent load carrying capacity and strength properties, the bridge needed only half of the amount of materials required for conventional concrete construction (Voo et al 2014). The first UHPFRC highway bridge, built in Iowa, USA, is the Mars Hill bridge, as shown in Fig.…”

An overall review of the structural behaviors of ultra-high-performance fiber-reinforced concrete (UHPFRC) elements subjected to various loading conditions needs to be conducted to prevent duplicate research and to promote its practical applications. Thus, in this study, the behavior of various UHPFRC structures under different loading conditions, such as flexure, shear, torsion, and high-rate loads (impacts and blasts), were synthetically reviewed. In addition, the bond performance between UHPFRC and reinforcements, which is fundamental information for the structural performance of reinforced concrete structures, was investigated. The most widely used international recommendations for structural design with UHPFRC throughout the world (AFGC-SETRA and JSCE) were specifically introduced in terms of material models and flexural and shear design. Lastly, examples of practical applications of UHPFRC for both architectural and civil structures were examined.

“…It has become commercially available in many countries such as Australia [2], Austria [3], Canada [4], Germany [5], Italy [6], Japan [7], Malaysia [8], Netherlands [9], New Zealand, Slovenia [10], South Korea [11], Switzerland and the United States [12]. A search of the literature has identified more than 100 bridges constructed with UHPC in some or all of its major components and is a solution that embraces sustainable design [13,14].…”

High temperature behaviour of hybrid steel–PVA fibre reinforced reactive powder concrete

Reactive powder concrete (RPC) with dense microstructure are found to perform poorly at elevated temperatures due to a build-up of pore pressure that causes explosive spalling. This paper presents the results of an experimental investigation of the behaviour of six RPC mixes containing hybrid steel and polyvinyl alcohol (PVA) fibres, following exposure to high temperatures up to 700°C. Residual compressive strength, static elastic modulus and ultrasonic pulse velocity measurements were carried out for all the RPC mixes. A mix containing hybrid steel-PVA fibre is proposed as suitable for hightemperature applications based on these results. Further tests were conducted for the mix at a hot state using a specially designed furnace-loading frame assembly. The hot-state elastic modulus, free thermal strains (FTS) and transitional thermal creep (TTC) were measured at the hot state. Residual compressive strength results for all the mixes indicated an initial increase in strength up to 300°C, followed by a drastic drop. No apparent changes in elastic modulus and ultrasonic pulse measurements were observed till 300°C, after which both dropped sharply. RPC containing only either steel fibres or only PVA fibres showed some form of instability, which was explosive in some cases. RPC with no fibres was also susceptible to explosive behaviour; however, the addition of hybrid fibres seemed to have beneficial effects. A mix containing equal volumes of steel and PVA fibres occupying a total fraction of 2 % by volume was found to give the best results. The FTS of that mix was similar to that of siliceous aggregate concretes, and the TTC was significant above 250°C.

“…However, it is to be expected that prices will decrease, if the market for ultra‐high performance concrete develops and local circumstances are taken into account. For example the material costs of a UHPC mix with 2 Vol.‐% of high strength steel fibers could be reduced to about 500 to 600 €/m 3 () within the scope of a research program for sustainable bridge construction with UHPC in Malaysia. Moreover, attention must be paid to particular characteristics of UHPFRC such as fiber orientation, fiber content, and fiber slenderness and the corresponding influence on the postcracking behavior and the brittleness of the material, for which the requirements should be defined and monitored in an appropriate way for each individual project.…”

“…The use of UHPFRC for precast elements in bridge construction is particularly economical if costs can be saved in the construction process due to the lower dead weight. A good design example for such an application is the Batu 6 bridge in Malaysia, a single span box‐girder road bridge with a span length of 100 m which consists of 36 precast bridge elements with a dead weight of a regular segment of only 17 t. The bridge could be easily assembled with a rail system on a falsework and only a small crane was necessary on one abutment side. All segments could be assembled in only 18 days…”

Due to the favorable material properties, Ultra‐High Performance Fiber‐Reinforced Concrete (UHPFRC) opens up new potential for precast options in PC bridge construction. On that matter, this article outlines the application, the load‐bearing behavior and advantages of two different possibilities: slender prestressed bridge girders and a prestressed trough‐shaped bridge element. Prestressed bridge girders made of UHPFRC allow for the realization of very slender cross‐sections with thin webs. For these beams, the shear capacity is the governing design issue. Hence, further investigations on the shear behavior with a variation of the fiber content, the prestressing level as well as the amount of shear reinforcement were undertaken. In this context, also size effects were examined using specimens with different construction heights up to 1.0 m. To enable testing of a high number of specimens with realistic cross‐sectional dimensions and at reasonable effort, an innovative experimental setup was developed and used for the investigations. Apart from these laboratory tests the present article deals with the pilot application of a railway bridge made of UHPFRC in Germany. The design and construction process as well as measurement results of the load and deformation behavior of the prestressed precast bridge element are presented and discussed.
