Abstract: Recently, nanoparticle injection technology has been developed for the remediating and repairing cracks in wellbore systems that can be used for underground CO2 storage. The repair technology can seal the cracks and prevent ...

Abstract: In this study, the hydration kinetics of ultrahigh-performance concrete (UHPC) with carbon nanofibers (CNFs) are investigated. According to classic nucleation theory, nanomaterials, such as CNFs applied in cementitious ...

Abstract: This paper presents numerical modeling of nanoparticles injected into cementitious material using the electromigration method. In order to remediate leaking wells in CO2 storage formations, beneficial nanoparticles can be ...

Abstract: This paper presents an experimental study on how the crack-parallel stress affects the fracture properties of fiber-reinforced concrete (FRC) using the gap test—a new simple fracture test invented and used for concrete at ...
