UHPC, also known as Ultra-High Performance Concrete is one of the best known solutions developed to address some of the main design conflicts, service life & life cycle costing issues that are linked with the use of concrete. It is a class of concrete that is defined by its exceptionally high strength and its durability. UHPC has been since used for specialized applications that demand superior strength and corrosion resistance.
The use of UHPC has expanded to applications that require a high level of strength in narrow profiles such as bridge spans and building facades where in the material’s strength, wear resistance, lighter weight as well as lower life cycle costs are a driving demand. Why should we limit ourselves while concepts are large and infinite at hand?
UHPC manufactured by POLUX can structurally be compared to steel than traditional concrete. As a result, far less material is needed to achieve the same structural requirements. This provides much lower weight, lesser substructure when used in facades as well as lowers shipping and installation costs. Since UHPC does not contain the basic capillary pores of a traditional precast or glass-reinforced concrete, it does not absorb water and thus not degrade in demanding freeze/thaw or alternating marine conditions.
Fiber types often used in UHPC include high carbon steel, PVA, Glass, Carbon or a combination of these types or others. The ductile behavior of this material is a first for concrete, with the capacity to deform and support flexural and tensile loads, even after initial cracking. The high compressive and tensile properties of UHPC also facilitate a high bond strength allowing shorter length of rebar embedment in applications such as closure pours between precast elements.
UHPC construction is simplified by eliminating the need for reinforcing steel in certain applications and the material’s high flow characteristics that make it self-compacting. The UHPC matrix is highly dense and has a minimal disconnected pore structure which results in a low permeability which prevents the ingress of harmful materials thus yielding superior durability characteristics. To bring any profile/form according to architectural needs.
