Green cement in the US is becoming big business

28 March 2024, Published under Cement News

The US cement market has been playing catch-up with markets such as Asia where the share of the market held by supplementary cementitious materials (SCM) has grown substantially over the last decade. While factory-produced Portland limestone (Type IL) cement is now rapidly expanding its market share in the US, future innovation is seeking to increase clinker replacement by SCMs even further with the production of a new generation of green cements.  SCMs such as fly ash and slag cement cur...

How best to tackle decarbonisation now?

10 February 2023, Published under Cement News

This week Carbon Re released its 'Three technologies to reduce climate change' white paper that provides recommendations to plant owners to reduce energy consumption. While there is good news in that Carbon Re identifies 13 technologies that can make a combined impact on cement plant decarbonisation to reduce global CO 2 emissions by 0.8Gta in the next decade, it will rely on policymakers and outside investment to achieve such significant reductions. Over 80 per cent of the savings ...

UK scientists look to develop zero-emissions cement

18 July 2022, Published under Cement News

Scientists at the University of Cambridge, UK, have been replacing lime flux with used cement paste for steel recycling.   The resulting slag could, in turn, create a zero-emissions cement in a closed-loop process. ‘If the electric arc furnace [for steel recycling] is powered by non-emitting electricity, the only significant emissions in today’s steel recycling come from making the lime flux. So, with our process, it looks like we can make zero-emissions steel and zero-emissions ceme...
