UK: Cemex UK has announced the launch of Viabase, an engineered asphalt concrete. The company says that the product is especially suited to use in residential housing estate roads, where it will be exposed to construction traffic before being surfaced after houses are built. The launch supports the UK government’s drive to increase house building to 300,000units/yr.

Europe regional asphalt, paving and building products director Carl Platt said, “With Viabase, we are pleased to offer a way to ensure the longevity of housing development roads, which standard materials struggle to provide if the surface course is not placed soon after. Viabase provides a highly durable, low maintenance surface which will meet the challenges presented by heavy duty vehicles and prevent long-term problems in the overall pavement construction.”

The company will produce Viabase at all its UK asphalt plants, where it will be available for delivery to customers or collection.

UK: SigmaRoc has launched Greenbloc, a cement-free concrete block. The product reduces emissions by 77% compared to concrete blocks produced with Ordinary Portland Cement (OPC), corresponding to a reduction of 1.1kg/block.

Chief executive officer Max Vermorken said, "Our Greenbloc range and brand is the brainchild of our innovation and technical teams. It addresses a key challenge in the building products industry - the embodied CO₂ in one of the most widely used building materials: the concrete block.

UK: HeidelbergCement subsidiary Hanson has installed a solar and wind-powered hydrogen generation demonstration unit at its Port Talbot Regen ground granulated blast furnace slag (GGBFS) plant in Port Talbot in Neath Port Talbot. The company says that the project is part of a collaboration with Swansea University’s Energy Safety Research Institute under the European Research and Development Fund’s Reducing Industrial Carbon Emissions initiative. The hydrogen generated by the installation will replace natural gas in the GGBFS plant’s burners.

Head of sustainability Marian Garfield said, “It is estimated that cement is the source of just under 2% of UK CO₂ emissions. With demand for cement and cement replacement products predicted to increase by 25% by 2030, researchers and industry are working hard to reduce the level of CO₂ emissions associated with production. As a leading manufacturer, we take our responsibility very seriously. In the UK we have already achieved a 30% reduction in CO₂ emissions since 1990 across the business and have set an ambitious new target of a 50% reduction by 2030 from the same baseline. We are constantly looking to improve energy efficiency and carbon reduction at our cement and Regen GGBFS plants, so we are delighted to be involved with this innovative research project.”

US: The US Department of Energy has awarded a grant to Cemex USA, UK-based carbon capture and storage (CCS) specialist Carbon Clean and Oak Ridge National Laboratory. The grant covers the implementation of a CCS system at Cemex USA’s Victorville cement plant in California, in addition to the development of a commercially viable carbon utilisation solution. The producer says that the study is due to last 30 months.

President Jaime Muguiro said, “Cemex is committed to being part of the solution to reduce carbon emissions globally and to deliver net-zero CO₂ concrete to all of our customers by 2050.

The company says the additional restored land from its Needingworth quarry will increase the area of the reserve to 298ha.

Unit manager Hilton Law said, “The Ouse Fen reserve is an outstanding example of minerals extraction leading to habitat creation on a landscape scale and highlights the benefits that managing the land left behind from quarrying can make in shaping and improving habitats for wildlife. We are proud to support the RSPB, Cambridgeshire County Council and others involved in the project, which will make an invaluable contribution to achieving UK biodiversity targets and securing the future of important wildlife habitats and species.”

UK: Cemex will supply 40,000t of lining-sprayed concrete for the construction of the 13km central section of the Thames Tideway sewer project in Greater London. Engineering partners Ferrovial Construction and Laing O’Rourke will use the concrete for shafts and launch tunnels. The company produced the concrete at its Buxton, Derbyshire concrete plant. It says that it offers ultra-high strength, consistency and two-hour workability in line with the stringent requirements of the job. It also needs to be pumpable with a pipeline length of up to 400m. The producer will deliver up to 3000t/month of the concrete to Central London over ‘a few months.’

Europe, Middle East, Africa and Asia president Sergio Menendez said “The Thames Tideway Tunnel project is one of incredible scale which will solve serious capacity issues with London’s sewer system and have considerable benefits for the area’s wildlife and population, while also preventing pollution, creating jobs, a rejuvenated river economy and new areas of public space.” He added “This is a remarkable piece of engineering, and we’re proud to be working with world-class contractors to build this key infrastructure in the most sustainable and cost-effective way possible for one of the world’s greatest cities.”

The 25km ‘Super Sewer’ will conduct the city’s sewage to a new treatment facility at Abbey Mills in the Borough of Newham. The central section runs between 30m and 60m below the Thames past part of West London, Westminster and the City of London.
