Low carbon concrete
Heidelberg Materials EcoCrete® low carbon concrete
Sustainable construction with up to 85% less CO2 emissions
Heidelberg Materials has developed its EcoCrete® range of low carbon concretes to make it easier to access low carbon concretes. EcoCrete® reduces the CO2 emissions associated with standard CEM I concrete with up to 85 per cent, helping contractors and clients meet their carbon reduction targets.
They contain Regen GGBS (ground granulated blastfurnace slag), a by-product of iron-making, as a replacement for some of the cement content in the concrete. Using GGBS reduces the embodied CO2 in a concrete mix by around 780kg for every tonne of CEM I Portland cement (PC) it replaces. .
It also increases the long-term durability of structures, conserves natural resources for future generations as it does not require the quarrying of materials and prevents the slag being disposed of as landfill.
There are three products in the range:
EcoCrete®: reduces CO2 by 30-64 per cent compared with CEM I concrete
EcoCrete® Extra: reduces CO2 by 65-79 per cent
EcoCrete® Elite: reduces CO2 by up to 85 per cent
All products offer the high quality and reliability features associated with our ready-mixed concrete but with the benefit of significantly reducing CO2 emissions. Wherever possible we use recycled water to produce EcoCrete®, adding to its sustainability credentials.

The input values we use to calculate the CO2 emissions of a concrete mix are externally verified and we can use this data to support our customers with a kg/CO2/m³ indication for each mix. Where required, an indicative EPD* can be generated using lifecycle assessment tools aligned with the product category rules for Type III construction products to EN 15804. These detail the CO2 emissions for a concrete mix and provide further detail of where the CO2 emissions occur along the value chain.
* Indicative EPDs are not externally verified
Bespoke low carbon concrete mixes
EcoCrete® in practice
EcoCrete used for Buchanan Wharf project
Europe's largest Cemfree concrete pour
Heidelberg Materials supplied Cemfree concrete in a continuous 10-hour pour as part of an Access for All scheme at Chatham Railway Station, Kent. It is the first time the product has been used on a Network Rail infrastructure project and is the largest Cemfree pour to date (May 2021).
The Densgate Square development in Manchester has been constructed using 110,000m3 of in-situ concrete to create the walls, floors, foundations and columns and Heidelberg Materials technical team were involved in the early-stage design discussions with the contractor and design engineers regarding the bespoke suite of concrete mixes required.
BREEAM ‘excellent’ environment performance rating achieved for 20 Fenchurch Street, the Walkie Talkie
This building was designed to achieve a BREEAM ‘excellent’ environment performance rating. The use of EcoPlus concrete played a big part in helping achieve this through the correct selection of its constituent parts. Read the full .
Heidelberg Materials is a member of the Quality Scheme for Ready-mixed Concrete (QSRMC) and all our products carry this certification.
