Influence of Cracking on Oxygen Transport in UHPFRC Using Stainless Steel Sensors

open access: yesApplied Sciences, 2019
Reinforced concrete elements frequently suffer small cracks that are not relevant from the mechanical point of view, but they can be an entrance point for aggressive agents, such as oxygen, which could initiate the degradation processes. Fiber-Reinforced

Ultra-High-Performance Fiber-Reinforced Concrete: Fresh Properties

open access: yes, 2022
UHPC is a cement-based composite that is used in new construction and/or renovation of existing structures to increase their service life. It is a unique composite material that may be used as an alternative to concrete in harsh conditions. Following decades of research and development, a wide range of commercial UHPC compositions are now accessible ...
