Influence of Recycled Aggregate on Shear Behavior of Steel Fibrous SCC [PDF]

, 2018
Of all the different kinds of failures in concrete, shear failure is a sudden and brittle and occurs abruptly without any prior warning. To avoid these types of failures in concrete, beams are traditionally reinforced with stirrups at closer spacing ...

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research

Study on Recycled Concrete Powders as Mineral Admixture in Recycled Concrete

IOP Conference Series: Earth and Environmental Science, 2019
Abstract The process of recycling waste concrete generated fine powders with a particle size of less than 0.16mm; it contains a large amount of hardened cement and unhydrated cement and has high activity. In order to meet the requirement of sustainable development in concrete industry, this study aims to improve the recycle use level of ...

Academic misconduct appeal services in China: Platform logics, self‐platformization and implications for integrity education

British Educational Research Journal, EarlyView.
Abstract Academic misconduct appeal services have quietly emerged within China's education marketplace, with commercial agencies promoting themselves on social media to assist international students facing misconduct hearings. While existing research on academic integrity has emphasized prevention and detection, far less attention has been paid to what
