As a novel green material, Ultra-high performance concrete (UHPC) has favourable application prospects. Currently, the ultimate shear capacity design of UHPC beam is carried out using empirical or semi-empirical methods. These methods involve approximations, which are not always reliable, and their scope limited. In view this, test was conducted on eight rectangular beams. The span to depth rat...

The converter steel slag is a by-product during the steel-making process, which usually acts as an inert ingredient in construction due to relatively low reactivity. However, its mineral composition results high reactivity CO2 rich environment. This study reveals modification of by ambient pretreatment, and application modified supplementary cementitious material (SCM) design eco-friendly ultra...

The excellent seismic performance of concrete-filled steel tube (CFST) structures has been widely recognized, but there is a paucity research on composite columns using UHPC with added fibers. This paper presents the experimental studies and numerical analyses OpenSees ultra-high fiber-reinforced concrete (UHPSFRC)-filled square tubular columns. Five half-scaled specimens UHPSFRC-filled were te...

The effect of various parameters on the flexural strength (FS) ultra-high-performance concrete (UHPC) is an intricate mechanism due to involvement several inter-dependent raw ingredients. In this digital era, novel artificial intelligence (AI) approaches, especially machine learning (ML) techniques, are gaining popularity for predicting properties composites their better precision than typical ...

Evaluation of the ultimate strength for UHPFRC (ultra-high-performance fiber-reinforced concrete) flexural members was conducted. In this study, an experimental program about beams conducted with effect fiber volume fraction, shear span to depth ratio, and compressive matrix as main variables. Among them, it found that fraction variable had greatest influence on strength. The inclusion 2% steel...

Reactive powder concrete (RPC) is an ultra-high-performance (UHPC) developed years ago by Bouygues, with the aim to build strong, durable, and sustainable structures. Some differences can be underlined between RPC high-performance (HPC); that say, exhibits higher compressive flexural strength, toughness, lower porosity, permeability compared HPC. Microstructural observations confirm silica fume...
