Abstract: The ultrahigh-performance concrete (UHPC)-normal strength concrete (NSC) composite has been increasingly used for improving mechanical performance and durability of engineering structures. The UHPC-NSC composite structures ...

Abstract: This study demonstrates the use of novel zinc phosphate (ZnPh)-treated steel fibers in ultra-high-performance concrete (UHPC), replacing the commonly used steel fibers. The effects of ZnPh-treated steel fibers on tensile ...

Abstract: To enhance the structural performance and durability of a conventional reinforced concrete (RC) cover slab over a culvert as well as to improve its spanning ability, this paper presents a novel ultrahigh-performance concrete ...

Abstract: Using low-retraction double-tensioned steel strands vertical prestress system (DTSSVPS) to replace finish rolled rebars (FRR) a vertical prestress system could effectively enhance the vertical prestress efficiency and ...

Abstract: Based on the limited information on the tensile stress–strain relationship of ultra-high-performance concrete (UHPC) with treated fibers, the objective of the present research is to experimentally investigate the flexural ...

Abstract: Ultra-high-performance fiber reinforced concrete (UHPFRC) exhibits strain hardening and multiple cracking behaviors when subjected to tension load. There are limited studies on the effect of steel fiber aspect ratios on ...

Abstract: This research aims to experimentally investigate the flexural behavior of ultra-high-performance concrete (UHPC)–steel composite beams with joints under a negative bending moment in order for the results to be used in the ...
