Resilience and low carbon built in
We are developing new products that can deliver a low carbon impact through reduced energy, greater use of recycled material, or reduced raw materials to produce the same performance.
Low energy asphalt (LEA) uses less energy and a higher percentage of recycled material than conventional asphalt but can be laid in the same way, and is ready for use sooner. There are also health and safety benefits for surfacing operatives due to the reduced heat.
We produce a cement replacement called Regen (ground granulated blastfurnace slag) which reduces embodied CO2 in concrete and provides a number of other benefits. We are developing concrete mixes with higher Regen content as well as communicating the CO2 benefits of these products to customers.
We have also been active in the development of the publicly available specification (PAS) 8820, which looks specifically at low carbon concrete, and the greater use of cement replacement in concrete mixes.
