ACCIONA pilots novel cement-free concrete pavement in Dubai
ACCIONA has successfully piloted an innovative cement-free concrete pavement.
Unveiled in Dubai on the 1st of July, 2026, this pioneering initiative represents a major leap forward for low-carbon transport infrastructure. The newly developed prototype pavement utilises fourteen precast slabs, all of which have been manufactured using a completely novel, cement-free concrete formulation. By replacing traditional clinkers with repurposed industrial by-products that act as a high-performance binder, ACCIONA has marked a decisive step towards the development of infrastructure with a substantially lower environmental footprint. This advancement is particularly timely, as it aligns perfectly with the rapidly growing demand for highly sustainable construction solutions across the Middle East.
The pilot pavement has been strategically installed directly on the access road leading to ACCIONA’s Equipment Park. Spanning a total surface area of 108 square metres, this site was deliberately chosen to serve as a comprehensive, full-scale demonstrator. The primary objective of this demonstrator is to rigorously evaluate the pavement's structural and material performance under exceptionally demanding environmental conditions. Furthermore, it will be tested against the intense wear and tear caused by heavy-vehicle traffic.
The evaluation process will monitor how the novel concrete withstands various extreme stressors that are typical of infrastructure environments situated within arid and semi-arid regions. These operational stressors prominently include prolonged exposure to high ambient temperatures and severe surface abrasion.
To successfully produce this advanced geopolymer concrete, ACCIONA utilised a specific blend of industrial by-products. The composition includes fly ash, which was supplied directly from a thermal power plant, alongside steel slag derived from blast-furnace steel production operations. The steel slag was provisioned by CEMCO Cement Trading, highlighting the collaborative nature of this sustainable supply chain. These carefully sourced sustainable materials undergo a sophisticated chemical activation process to form the final concrete product. This critical chemical activation was made entirely possible through a strategic partnership with MC Bauchemie Spain. As a vital project collaborator, MC Bauchemie Spain supplied the essential chemical activator whilst also providing the specialised technical support required to develop and meticulously fine-tune the new concrete formulation.
The environmental benefits of this new concrete are profoundly significant, primarily driven by the total elimination of clinker from the manufacturing process. As a direct result, the cement-free concrete delivers a remarkable 76 per cent reduction in carbon dioxide emissions when compared with conventional reference cement, specifically CEM I.
However, the advantages of this pavement extend far beyond its lowered environmental impact. The solution features a modular precast design, which fundamentally streamlines the entire lifecycle of the infrastructure. This modularity simplifies the initial manufacturing phase, accelerates on-site installation procedures, and drastically reduces ongoing maintenance requirements. Furthermore, the precast slabs actively support circular economy principles by facilitating straightforward reuse and efficient recycling at the end of their operational life.
These modular and sustainable characteristics are considered particularly relevant for the Middle East market. Throughout the region, large-scale infrastructure projects, extensive logistics corridors, expanding industrial zones, and new urban developments are increasingly prevalent. Such vast developments fundamentally require construction solutions that are not only highly durable but also resource-efficient and low-carbon, ensuring they remain aligned with rigorous national sustainability and circular economy agendas.
This specific initiative is intrinsically linked to the broader European LIAISON project. ACCIONA’s participation in this European innovation project aims to expertly design and validate sustainable solutions for developing low-carbon transportation infrastructure. Ultimately, these solutions possess significant potential for widespread applicability across international markets, very much including the Middle East.
The successful deployment of this pavement pilot further cements ACCIONA’s position as a global company and a recognised leader in the provision of regenerative solutions for a decarbonised economy. The organisation's extensive business offering encompasses a wide array of sustainable sectors, including renewable energy generation, water treatment and management, eco-efficient transportation and mobility systems, and resilient infrastructures. Demonstrating a long-standing commitment to environmental stewardship, the company has successfully maintained a carbon-neutral operational status since 2016. Illustrating the vast scale of its global operations, ACCIONA recorded impressive sales figures of €8.1 billion in the year 2021. Today, the enterprise maintains a robust and active business presence spanning across more than sixty countries worldwide.
