Hanson UK delivers 10,000th Regen GGBS to Hinkley Point C

16 September 2021, Published under Cement News

The 10,000 th load of Hanson’s Regen ground granulated blastfurnace slag (GGBS) has been delivered to the Hinkley Point C (HPC) new nuclear power station construction site in Somerset, UK. The material is helping to enhance the project’s low-carbon credentials before it begins operations to supply some 6m homes with low-carbon electricity.     Regen GGBS is a replacement product for some of the ordinary Portland cement (OPC) content in concrete, which can significantly reduce the environ...

Alkali-activated materials

16 March 2021, Published under Cement News

While blastfurnace slag and metakaolin are known to produce a binder phase following alkali activation, the range of alkali-activated materials is wider than these two materials. This month Arthur Harrisson provides an overview of low-and high-calcium precursors that are subjected to alkali activation to produce binders. Figure 1: fly ash, a low-calcium AAM precursor Materials that arise as waste or a by-product from industrial processes other than Portland cement manufacture ha...

Hanson UK launches green hydrogen power unit

11 February 2021, Published under Cement News

A new green hydrogen power demonstration unit has been developed and installed at Hanson UK's Regen ground granulated blastfurnace slag (GGBS) plant in Port Talbot, south Wales.This is part of the company's GBP9.2m 'Reducing Industrial Carbon Emissions' (RICE) project, funded by the European Regional Development Fund (ERDF).

Portland cement, lime and alkali-activated binders

15 May 2019, Published under Cement News

Following on from last month’s discussion regarding the production of alternatives to Portland cement clinker, Arthur Harrisson takes a closer look at alkali-activated binders. Fly ash needs to be activated to produce an effective binder In a recent article 1 about the production of alternatives to Portland cement clinker, in the discussion of the preferred options of Gartner and Sui 2 , mention was made of alkali-activated binders, which were considered worthy of a paper of th...

Steelmaker ArcelorMittal has increased its shareholding in Ecocem France. By the end of May, ArcelorMittal will hold a 49 per cent stake in the cement company, compared to 30 per cent to date. The joint venture Ecocem France was created in 2007 by ArcelorMittal and the Irish group Ecocem Materials to develop the production of granulated blast furnace slag (GGBS), a by-product of steel manufacture by ArcelorMittal in France. Ecocem France currently operates a 0.7Mta ground slag productio...

UK: Hanson reopens GGBS grinding plant

21 February 2017, Published under Cement News

Hanson has re-opened its ground granulated blast furnace slag (GGBS) grinding plant at Teesport Docks in Middlesbrough, UK, creating 20 new jobs. The plant was mothballed during the recession in 2009, but the upturn in construction activity prompted Hanson to reopen the site. The raw material was originally sourced from the nearby steel works, which has now closed. In future it will be imported, helping to sustain the docks. Site Manager, Duncan Felgate, said: "It has taken nine months to ...

Fly ash and slag cements

27 July 2016, Published under Cement News

While cements containing fly ash or GGBS have different strength properties to ordinary Portland cement, they also benefit from improved durability and workability. A key factor in strength development is the provision of calcium silicate hydrate. Concrete made with cement which includes fly ash or ggbs will have different strength properties than that made with cement which contains purely clinker and gypsum Although a particular material may be cheaper per kilogram or per t...

Ecocem to invest EUR5m in two UK terminals

21 March 2016, Published under Cement News

Ireland-based Ecocem will open a new terminal at Runcorn, on the Manchester Ship Canal, to help the company import into the UK, and plans a second terminal later this year in the southeast of the country. The two terminals represent an investment of EUR5m.
