Cemex launches Prime admixtures to cut concrete carbon

Cemex has unveiled a new family of advanced chemical admixtures designed to reduce carbon emissions in concrete and cement while improving strength, durability and flexibility across a wide range of construction applications.

Branded as Prime, the new admixtures range is being rolled out across Europe, the Middle East and Africa (EMEA) as part of a broader strategy to accelerate decarbonisation and support modern construction demands.

Developed through Cemex’s in-house admixtures unit and global R&D centre in Switzerland, Prime formulations are engineered for compatibility with lower-carbon cements, recycled materials, and supplementary cementitious materials (SCMs) – all while maintaining high performance. Cemex says the new products are designed to support bespoke and sustainable mix designs for ready-mix concrete, precast elements, mortars and more.

“Admixtures are essential components in modern construction,” said Dietmar Voetsch, director of admixtures for Cemex Europe. “We’re developing solutions in collaboration with our customers that meet the evolving challenges of our sector – with sustainability and performance at the core.”

The Prime range is the latest addition to Cemex’s Urbanisation Solutions portfolio, a global product platform aimed at supporting sustainable, safe, and resilient urban development. The launch follows Cemex’s wider ‘Future in Action’ climate strategy, which targets net-zero operations and includes goals such as:

• Reducing CO₂ per tonne of cementitious material to below 430kg by 2030
• Reaching 55% alternative fuel use across operations
• Cutting CO₂ per m³ of concrete to 150kg, a 41% reduction from 1990 levels

With urbanisation accelerating and stricter sustainability targets emerging across the concrete sector, chemical admixtures like Prime are expected to play a growing role in enhancing performance, reducing emissions, and helping contractors meet both design and regulatory requirements.

Customers in the EMEA region can now access the Prime range, with further regional launches planned throughout 2025.
