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