Hanson, the UK’s leading supplier of heavy building materials to the construction industry and part of the HeidelbergCement Group, has launched a new range of concretes that can reduce the embodied CO2 of construction projects. The EcoPlus range includes a blastfurnace slag product called Hanson Regen, which can be used to substitute ordinary Portland cement (OPC) in concrete. Ground granulated blastfurnace slag is a byproduct of the iron industry, and it can replace up to 70% of OPC content. Tonne for tonne, Regen can reduce embodied CO2 by around 850 kg compared with OPC. Other benefits include a lighter colour, and improved durability, particularly in structures where sulfates and chlorides are an issue.
“Our online carbon calculator shows the CO2 savings that can be made by specifying one of our eight standard EcoPlus mixes, which are suitable for foundations, pavements and structural projects. We can also design and supply bespoke mixes,” said Paul Lacey, Hanson’s head of sustainability and marketing.
