Concrete is a human-made stone. Simple and malleable, it is by far consolidated as the most used construction material worldwide. Its reinforcement and prestressing were key factors for the development of the cities and the industrial revolution. Concrete has experienced a progressive increase of its performance for centuries, which accelerated in the second half of century XX. Since 1950, the development of new admixtures and ultra-fine particles allowed the design of more compact and homogeneous dosages, facilitating the industrial use of concretes with higher strength. The Danish Hans Henrik Bache developed in 1981 the named as Densified Small Particle (DSP), a fine powder with plasticizer to achieve a high particle packing density. Five years later (1986), the addition of dispersed fibers to give ductility to this brittle material generated what is considered nowadays the first UHPC. Combined with a dense steel reinforcement, this composite material was named CRC (Compact Reinforced Composites). In 1995, the concept was developed to create the RPC (Reactive Power Concrete), which was based in removing the coarse aggregates, optimizing the granular mixture, and applying pressure before and during setting. Only one year before (1994), De Larrard and Sedran used for first time the term UHPC, referring it as a cementitious material with ultra-high performance thanks to the design of its mix using a high packing density model and the application of a moderate thermal curing. In the late nineties, several companies launched to the market their UHPC mixtures (Ductal^® from Lafarge, BSI/Ceracem^® from Sika and Eiffage, BCV^® from Vicat, CEMTEC Multiscale^®), trying to promote the use of commercial premixes in new demanding applications. Progressively, some of these products were no longer available in the market, being replaced by UHPC mixtures tailored locally for each application due to the gradual democratization of the technology. These uses were favored by the adoption in 2016 in France of the first world norm for UHPC (NF P 18-710: Complement for the Eurocode 2 with Specific Rules for Ultra-High-Performance Concretes; and NF P 18 470: Ultra-High Performance Concretes: Specifications, performance, production and conformity), which is still considered a relevant reference at international level. The first world application of UHPC in civil engineering was the Sherbrooke footbridge (1997, Canada), followed by an increasing number of applications in the field of civil engineering, architecture, and industry. The most active countries in this field are Germany, France, United States, Switzerland, Japan, and Spain. In the last, the first structure of UHPC was the Oveja’s Ravine Footbridge (44 m of span, 2012), which became also the first world truss footbridge made only with UHPC. It was designed by Juan Ángel López, co-founder of RDC. The members of this engineering company designed also the first UHPC bridge in Spain (2017), the first world UHPC floating farm (2016, having nowadays more than 15.000 m2 installed), and the first world use of UHPC in floating solar energy, installed in a 5 MW plant in the largest EU dam (2021, Alqueva, Portugal). All of them have been performed with Formex^®, the UHPC adaptable premix of RDC. UHPC is a material with a promising future. The universalization of its use passes through understanding the specific applications where it provides the best possible solution. Contrary to what might be assumed, many of these uses are not to replace traditional concrete and are not even in the construction sector. The path to discover them is to cooperate with different industries, to avoid preconceived ideas and to be openminded. In RDC we support companies and stakeholders to understand the applications where UHPC can improve the sustainability and costs of the current solutions, or can face new challenges that are not possible with the traditional materials.
