Recently, carbon materials with unique properties, such as high tensile strength and electrical conductivity, have been extensively investigated for the multi-functionalization of concrete. Previous studies mainly focused on improving performance normal-strength concrete using nanomaterials, nanotubes graphene nanoplates. Therefore, this study analyzed effect ultra-high-performance (UHPC) mixed...

Ultra-high-performance concrete (UHPC) is a form of cementitious composite that has been the most innovative product in technology over last three decades. broadly employed for design numerous forms construction owing to its excellent mechanical characteristics and durability, studies on behavior have grown fast While utilization ultra-high-performance bridge engineering (BE) limited high costs...

Ultra-high performance concrete (UHPC) has been demonstrated to be a realistic alternative less maintenance and significantly longer service life due its better mechanical properties low permeability. The bond of the deformed steel bar embedded in UHPC is critically important for safety structures. This paper conducted an experimental investigation on behavior bars UHPC. impacts loading method,...

The development of non-proprietary Ultra-High Performance Concrete (UHPC) is one way to reduce the initial cost construction. However, workability a major issue for which such mixtures are not practical in field conditions. Ultra-high performance cannot be achieved conditions if concrete placed, finished, and compacted properly during placement. In this research, six UHPC were developed (three ...

Due to its outstanding mechanical properties and durability, Ultra High-Performance Concrete (UHPC) hasbeen gradually used for different types of structures in recent years. However, the analysis environmental impacts assessment overall sustainability performance UHPC applications is quite limited.This study presents results determining total energy embodied CO2 emissions causing greenhouse eff...

Iron tailing powder (ITP) is considered to have the potential replace cement manufacture ultra-high-performance concrete (UHPC). However, performance of UHPC with addition ITP after exposure high temperatures more complex. This investigation prepares seven formulations by introducing different contents and investigates mechanical behavior (residual strength), bound water content, microstructura...
