Autoclaving of ultra‐high performance concrete (UHPC)
ce/papers, 2018AbstractBy the combination of an optimized granulometry, a reduced water–cement ratio and the use of superplasticizers ultra‐high performance concrete achieves a compressive strength of over 150 N/mm2 and a high resistance regarding acids and water‐soluble salts.

Ultra high performance concrete (UHPC) sleeper: Structural design and performance
Engineering Structures, 2020Abstract Both structural and material performance of railway sleepers are critical to ensure the safety of railway track structures. In this study, for the first time, ultra high performance concrete (UHPC) is adopted to the post-tensioning type of sleeper to prolong design life and reduce the maintenance of sleepers.

Functional microfibre reinforced ultra-high performance concrete (FMF-UHPC)
Cement and Concrete Research, 2020Abstract The present paper proposes a novel class of fibre reinforced concrete, realized by using shape memory alloy (SMA) fibres as reinforcement in ultra-high performance concrete (UHPC). SMAs can change their geometry imposed by a solid to solid phase transformation triggered by thermal activation or stress.

Structural Members Made of Ultra-High- Performance Concrete (UHPC)
2020 Advances in Science and Engineering Technology International Conferences (ASET), 2020Dubai is one of the fastest growing cities in the world. Construction industry has been in quest to meet this growth. High performance concrete has been of a great interest to the construction industry. In this research different design mixes were tried to produce concrete of ultra-high performance (UHPC).

Acid Resistance of Ultra High-Performance Concrete (UHPC)
2015Based on the knowledge of the deterioration mechanisms of different acid solutions the performance of UHPC – amongst others – in different acid environments was comparatively tested. The interconnection between the acid solutions and UHPC was examined by pH-value measurements, light microscopy (LM), scanning electron microscopy with energy dispersive X-

Multidiscipline Modeling in Materials and Structures, 2022
PurposeThe application of ultra-high performance concrete (UHPC) in anchorage zones can significantly improve the local compression performance of structures. However, the high cost and complex preparation of UHPC make UHPC difficult to be widely used in practice. This study proposes a method to strengthen the local compression zone of structures built

Ultra High Performance Concrete (UHPC) in case of fire
Ultra-high-performance concrete (UHPC) has exceptional mechanical properties at room temperature. However, there are no standardized procedures to characterize UHPC in fire. This is due to the lack of research on the subject, leaving gaps for experimental and numerical studies.openaire +1 more source
