Ultra-light UHPC slabs for many applications!

Good morning! Today I want to make a well-deserved mention to one of the most versatile precast elements that can be done with UHPC: The slab. UHPC slabs can provide efficient solutions in modular housing, balconies, structural flooring, industry, and civil engineering among others. Their main advantage compared to ordinary concrete slabs is that, for […]

History of the UHPC structures in Spain

Good morning friends! Here I come with the second post of June, which marks the beginning of the summer! Last week I was reading one of these papers that starts listing relevant applications made with UHPC up to date. I noticed that they did not mention any from Spain, and possibly the reason is that […]

Horizon Europe project NATURSEA-PV (2022-2026)

Background: The Horizon Europe project Natursea-PV (Novel Eco-Cementitious Materials and components for competitive, durable and bio-inspired offshore floating PV substructures) funds the research and development of novel materials for substructures oriented to floating photovoltaic systems in offshore environments. Particularly, an eco-UHPC is going to be developed for the design of a system composed by beams […]

H2020 project SMARTINCS (2019-2024)

Background: This project is implementing new life-cycle thinking and durability-based approaches to the concept and design of concrete structures, using self-healing concrete, repair mortars and grouts together with key enabling technologies. Part of the research is carried out integrating these technologies in UHPC. The potential of this project is to create a breakthrough in the […]

EMFF project OpenMode (2019-2021)

Background: There are several types of mussel farming systems, of which the most common are the longine (extensive), and the raft (intensive). The last has been traditionally used in Spain due to the high concentration of phytoplankton in the water and the availability of eucalyptus wood. As since 2018 Formex® beams are an option, RDC […]

H2020 project SELMUS (2016-2017)

Background: After the patent of the UHPC rafts in 2015, RDC required to build full-scale pilots of these floating structures to prove to the farmers their durability and suitability. This shaping strategy also required a wide communication and dissemination campaign to familiarize the sector with this new technology. Being RDC a small company and with […]

Design of the first UHPC bridge in Spain, located in Beniarjó (Valencia)

Background: RDC designed in 2018 the first UHPC road bridge built in Spain. The solution was required to rebuild a bridge over the Vernissa river, which was destroyed by the floods on year 2007. The bridge consisted of a bidirectional decks supported existing piles to save six spans, each of them of 10 m. The […]

Reparation of a bridge in Alcira with UHPC beams

Background: In 2019, a concrete bridge in Alcira (Valencia) suffered the impact of a truck, which destroyed its two first “double-T” beams. The contractor requested to RDC the design of the new two beams with UHPC, so if in the future there is a new impact of a truck against them they do not suffer […]

UHPC flooring for a terrace in a recycling plant in Guadassuar (Valencia)

Background: UHPC performance allows to design large format thin slabs, reducing the installation time and the number of joints in the area covered. In 2017, RDC designed with UHPC the slabs of the largest terrace of the recycling plant Ribera del Xuquer (Guadassuar, Valencia). In this case, texture and color were selected to achieve metallic […]

THE USE OF UHPC IN BRIDGES IN THE UNITED STATES OF AMERICA

Bridges where UHPC has been used in USA

Good morning, everyone! Today I would like to speak about the progress in the use of UHPC in the US, focused mainly in the most dynamic application in the last decade: The use in bridges to increase their durability and minimize their maintenance costs. This type of application was generalized previously in Switzerland with the […]
