The US Department of Transportation (DoT) has announced a US$5m funding opportunity for a research initiative on the use of steel slag in cement and concrete. The funding will support a partnership between the US DoT, in conjunction with a producer of steel in the US, and an accredited research university of higher education to reduce carbon emissions associated with extracting and manufacturing construction materials.  At this year’s Transportation Research Board Annual Meeting, US Tr...

Cement Australia signs haulage agreement with Pacific National

11 October 2023, Published under Cement News

Cement Australia has signed a three-year rail haulage agreement with Pacific National for the movement of cementitious materials across Australia. Pacific National will transport cement, sand, fly ash, slag and lime between Australia’s major cities and throughout North Queensland, on behalf of Cement Australia, using interstate and inter-city transportation. Compared to road transportation, rail haulage is more fuel efficient, therefore offering a transport system with lower emissions. A...

GGBS slag cuts 408Mt of CO2 from UK's OPC production in 2022

05 October 2023, Published under Cement News

In 2022, around 38.5Mt of ferrous slag were produced in the European Union and the UK. Approximately, 99 per cent of this could be used primarily as a building material and in fertilisers. This means that the by-products of the steel industry have substituted more than 1.1bnt of natural rock in the period from 2000-22. In addition, the use of granulated blastfurnace slag, replacing Portland cement clinker, in cement avoided the emission of 408Mt of CO 2 over the same period.    Last year...

CRH Ventures invests in Carbon Upcycling

22 February 2023, Published under Cement News

CRH Ventures announced its investment in Carbon Upcycling Technologies (CUT), a company whose patented technology aligns closely to CRH Ventures’ circular, zero-waste sustainability values.  CUT’s pioneering technology transforms local industrial byproducts and natural materials, such as slag, shale, and fly ash, into superior additives. This helps to significantly reduce clinker content and CO 2 emissions while enabling cement and ready-mix concrete manufacturers to produce more sustain...

EU calls for greater use of secondary raw materials

26 February 2021, Published under Cement News

The EU Parliament’s own-initiative report adopted this month calls for an upgrading of secondary raw materials. Among other things, it provides for stronger environment-oriented public procurement with mandatory minimum criteria, for example in the construction industry.   For the Euroslag European network and the FEhS Building Materials Institute, this is an important step towards a comprehensive approval of secondary building materials and their conditional prioritisation in public ...

Cemex and Carbon Upcycling to increase industrial waste use

04 November 2020, Published under Cement News

Cemex SAB de CV has signed an agreement with Carbon Upcycling Technologies to improve processing of residue or byproducts from industrial processes and to capture CO 2 to produce nanomaterials and low-CO 2 concretes. Cemex Ventures will work with Carbon Upcycling Technologies  to increase the 3Mta of industrial residue that Cemex uses for cement and concrete additions, and therefore reduce the volumes being sent to landfill. The initiative will increase the reactivity of industria...
