New UHPFRC for the realization of complex elements
Ultra High Performance Fibre Reinforced Concrete (UHPFRC), is a class of concrete defined by its exceptionally high mechanical performances, durability and refined aesthetics. Thanks to these characteristics and many project references, the worldwide development of UHPFRC, such as Ductal®, is booming since few years. Ductal® can be used either as a precast material or cast in-situ, for new constructions or repair and retrofitting. The range of applications is very large, from structural components to architectural façade, through the urban furniture, sunshades, etc. A significant R&D program led to the development of customized formulations that comply with the constraints of the projects and customers’ expectations. Various type of fibers can be used (metallic, organic, glass), for the formulations which can be either self-compacting or sprayable or even take a slope. Sprayed Ductal® offer news possibilities for the realization of 3D complex elements, for which the mold represents an important cost. The mechanical and durability performances allow an optimization of the dimensions (reduction of the thickness or increasing of the length and width). The watertightness for a façade could also be appreciated.
