Durability of an Ultra High Performance Fiber Reinforced Concrete (UHPFRC) under progressive aging

Ultra-High Performance Concrete: Mechanical Performance, Durability, Sustainability and Implementation Challenges

“…Likewise, UHPC showed very low permeability to oxygen as compared to that of NSC and HPC. For instance, the UHPC permeability to oxygen is less than 1 9 10 -19 m 2 (1 9 10 -18 ft 2 ), which is around 10 and 100 times lesser than that of HPC and NSC, respectively (Vernet 2004;Wang et al 2014). Furthermore, Roux et al (1996) found no penetration of carbon dioxide (CO 2 ) into UHPC specimens after 90 days of exposure.…”

Development of an eco-friendly Ultra-High Performance Concrete (UHPC) with efficient cement and mineral admixtures uses

“…Due to the specific cementitious system of UHPC (very small water/binder ratio and relatively high SP amount), it is observed that the pozzolanic reaction of FA is significantly retarded, which causes that a very limited amount of FA can react with Ca(OH) 2 after curing for 91 days.

Corrosion of Glass Fibres in Ultra High Performance Concrete and Normal Strength Concrete

“…% of ZrO 2 ), identified as Alki-Resistant glass (AR-glass) that demonstrated higher alkaline resistance just thanks to the addition of network-forming ZrO 2 . This type of glass is still being used for production of glass fibres for concrete mixtures, however, not even fibres made of AR-glass are completely inert to the strongly alkaline environment and they may corrode [15][16][17][18][19][20][21][22].…”
