From Aspdin to recycled concrete

25 October 2024, Published under Cement News

This week demonstrated more than most that the cement sector is still innovating after celebrating 200 years since Joseph Aspdin's patent for ordinary Portland cement (OPC). Refining this valuable building material has taken us to the point where Heidelberg Materials announced that it will now recycle concrete from demolition waste, creating a by-product that will be reused in cement manufacture. In future, the concrete already in the world can be recycled to supply new building materials, c...

Brimstone cement certified as ASTM C150

14 July 2023, Published under Cement News

Brimstone, the US-based industrial decarbonisation start-up, has received third-party certification that its cement meets or exceeds ASTM C150 standards for ordinary Portland cement (OPC), becoming the first ultra-low carbon, carbon-neutral or carbon-negative cement to meet this critical and universally-accepted industry requirement. "At Brimstone, we believe decarbonising cement relies on three essential principles: producing the exact same trusted material, at much lower carbon, an...

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...

The cement sector can't sit back on reducing CO2 emissions

22 April 2022, Published under Cement News

This week Credit Suisse published a revealing study entitled 'Global Infrastructure and Construction', which looks into the current state of the global cement industry's efforts to reduce carbon emissions. The report attempts to highlight which countries and cement companies are not yet making sufficient headway in dealing with their CO2 emissions. It may surprise many that the USA is the worst-performing nation in terms of one key metric, CO 2 per tonne of cement manufactured, which is re...
