Capital Concrete Builds On Early Success With Ecocem’s ACT Technology Across New Projects

Following the successful first use of an innovative low carbon technology at Wembley earlier this year, Capital Concrete has since supplied to two further projects - an extension in Bishop’s Stortford, Essex, and a swimming pool in Woking, Surrey.

Ecocem’s ‘ACT’ technology reduces the clinker content - the main source of CO₂ emissions - in cement, a key ingredient in concrete, cutting overall embodied carbon by up to 70%.

In the two recent projects, the technology was used in the footings and slabs of the extension, and in the pool’s foundations. Throughout both deliveries, Capital Concrete worked closely with the customer to supply the lowest embodied carbon concrete mix that met their sustainability goals and performance requirements.

As well as tailoring the mix to each project, the technical team at Capital Concrete had to make sure that the mix design was suitable to transport over a longer distance than usual and remained workable for between three and four hours.

Jack Sindhu, Technical Director at Capital Concrete, explains: “By replacing the clinker in cement with low-carbon materials such as limestone powder and recycled by-products from steelmaking, ACT can reduce embodied carbon by up to 70% whilst helping to maintain the end product’s quality and performance.”

Jack added: “The team has done a great job in the lab and on site to deliver ACT for the three successful projects we’ve been involved in so far.”

Luke Smith, Managing Director at Capital Concrete, said: “As our customers’ needs evolve, it’s important that we adapt. ACT allows us to meet growing demand for lower-carbon solutions while continuing to deliver the quality and reliability our customers expect.”
