The study is 80% financed by the European Regional Development Fund (ERDF).
UPCT science and advanced construction technology research group coordinator Carlos Parra said, “Stopping the use of concrete is not the solution, as it is a relatively accessible material that allows access to housing and multiple services for millions of people around the world and is also a material with high resilience against natural catastrophes such as floods, hurricanes and resistant to the passage of time.”
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.”

Italcementi’s Bergamo research centre to stay in Italy
03 February 2021Italy: An agreement between Italcementi and its unions has confirmed that its Bergamo research centre to stay in Italy. The agreement with the FenealUil, Filca-Cisl, Fillea-Cgil, Italcementi RSU unions is intended to preserve jobs at the company, maintain at least 15,000 hours/yr of research at the site and dedicate at least 1% of the company’s profits towards research and innovation. Parent company HeidelbergCement was reportedly considering a relocation of the centre to Heidelberg in Baden Württemberg, Germany in late 2020.
Separately, Italcementi’s grinding plant at Salerno has been approved to continue producing white cement. The decision follows staff cuts at the cement producer, according to the Il Mattino newspaper.
Tunisia: Carthage University, Ciments de Bizerte, the Tunisian Ministry of Higher Education and Scientific Research and the University of Algarve faculty of science and technology have concluded a study into the heavy metal content of CEM-I and CEM-II cement. The study found that both types of cement contain traces of arsenic, barium, boron, cadmium, chromium, copper, manganese, nickel, lead, strontium and zinc in equal measure, according to the Journal of Engineering.
Carthage University said, "Heavy metals in cement can originate from a variety of processes in production, including their initial presence in raw materials and fuel, incorporation into kiln refractory brick, metal erosion from the raw material grinding process and in additives such as gypsum, as well as cement kiln dust."

Yorkshire Water tests new concrete surface technology in the UK
14 January 2021UK: Yorkshire Water is trialling a new concrete surface applicant designed to prolong the lifespan of concrete. It says that the alumina and zirconia silicate ceramic surface treatment protects concrete from wet/dry and freeze/thaw cycles, peeling, flaking, chalking and delaminating. This reduces the need for replacement of concrete structures, reducing CO2 intensity by 43% compared to bare concrete, according to the company. Advanced materials producer Haydale supplied the product.
Senior project manager Jonathan LeMoine said “In early 2021 we will be using one of our capital partners to apply the material to a number of our chemical bunds. The results will be immediately apparent and will pave the way for a larger programme of works protecting our assets.” He added “We often invest in trialling new technologies and techniques to pave the way for lower emissions in our capital expenditure (CAPEX) and operating expenditure (OPEX) solutions. We’re excited to see the results from this trial, and hope that it will provide a low carbon alternative to demolishing and rebuilding.”
