Ecocem has achieved the ASTM C1157 certification in the US for its low-carbon ACT cement technology.

The Irish company, whose GGBS alternative to traditional cement was used to build the Aviva Stadium, described the certification as a major milestone that affirms the performance, durability and reliability of ACT.

The accreditation confirms that ACT meets or exceeds the industry benchmarks for strength and durability while reducing carbon emissions and energy usage.

ACT can reduce CO2 from cement manufacturing by cutting clinker content by 70 per cent and replacing it with limestone and locally-sourced supplementary cementitious materials (SCMs).

Clinker is the key reactive component in cement that is responsible for 90 per cent of its carbon emissions.

The company expects that its technology will offer a solution available domestically at a time when the US imports nearly a quarter of its concrete while scaling a cleantech innovation into one of the world's largest construction markets.

Ecocem has said its products can help the cement industry to decarbonise by 50 per cent by the end of the decade.

“This is a significant moment for Ecocem and for low-carbon cement globally," said Donal O’Riain, founder and group managing director of Ecocem.

“Over the past 10 years our solutions have seen significant traction across Europe.

"The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise through improved efficiency and without increasing costs or complexity.”

The announcement comes as Ecocem moves forward with its first North American project, the proposed terminal and milling operation at the Port of Los Angeles.

Currently in the early planning stages, the facility is intended to establish a reliable supply chain for producing low-carbon cement in California.

Ecocem has recently received regulatory approvals in France and entered into partnerships with global construction leaders such as Bouygues, Vinci and Titan Group.

In February, Ecocem announced plans to spend €50m to build its first ACT production facility in Dunkirk and increase production capacity to over 1m tonnes per year by 2026.

In May, a further €170m was committed to the construction of four new production lines in France and to accelerate the delivery of ACT.

The company has also helped to construct Le Grand Paris Express, the Paris Olympics athletes' village and the UK's HS2 high-speed railway.
