Ultra-High Performance Concrete (UHPC)
best online pharmacy to buy isotretinoin Ultra-High Performance Concrete is a class of advanced cementitious material with greater strength, tensile ductility, and durability properties when compared to conventional or even high performance concrete. Steel fiber is added to all UHPC to achieve specified requirements. UHPC applications include: highway bridges, field cast connections, rehabilitation, and façades.
Parets del Vallès The main characteristics of UHPC are achieved through the following three principles:
- homogeneity enhancement
- density enhancement
- ductility enhancement
http://contextaudio.com/?author=1 Ductility is enhanced by the introduction of steel fibers. As the matrix is very brittle, steel fiber reinforcement is added to obtain elastic-plastic or strain-hardening behavior in tension. Typically, UHPC has fiber contents of 2% (264lb/cy) or more by volume.
