Experimental Testing of Layered UHPFRC Beams

Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) is fine-grained cement-based material characterized by high compressive strength (exceeding 150 MPa) and high modulus of rupture (over 15 MPa). The results of strengths depend on the size of the tested element, the loading rate and the boundary conditions during a testing. This type of material is used in a lot of countries (e.g

Reinforced concrete - Wikipedia

Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete

Seismic fragility curves for vulnerability assessment of

The results obtained show that, as anticipated, unreinforced concrete lined tunnels generally show a higher probability of conceding damage than conventional and fiber reinforced cases. However, as the level of damage intensifies, i.e. from minor to extensive damage states, this deficit in seismic performance reduces, from approximately 25% to

The world's first building made from carbon-fiber

Two months ago, the foundation was poured for CUBE, a 2,200-sf, two-story building on the premises of Technical University Dresden in Germany, that claims to be the world's first building made entirely of carbon-fiber reinforced concrete.. This 5 million Euro (US$5.63 million) project, which was delayed because of the coronavirus outbreak, is now scheduled for completion next spring.
