Eagle Materials Inc has entered an agreement granting exclusive rights to build and operate three facilities processing up to 240,000tpa of Terra CO 2 ’s Opus SCM, a supplementary cementitious material, from common quarry byproducts or other silicate-rich feeds. The facilities are earmarked for the Greater Denver market. Concrete producers and contractors in this region are preparing for next year’s implementation of the Buy Clean Colorado Act, which promotes low carbon construction mater...

Materials scientists call for wider adoption of low-carbon cement

15 November 2023, Published under Cement News

Convening at a symposium in Paris hosted by Ecocem , Europe’s leading low-carbon cement technology business, scientists shared latest research papers on low-carbon cement technologies, and focussed on ideas and materials which can accelerate decarbonisation of the sector. The meeting called for the cement and construction sectors to urgently adopt low-carbon cement technologies to radically reduce CO 2 emissions.   The scientists concluded that adopting the latest developments in low-c...

ASTM proposes new standards for SCMs

03 May 2023, Published under Cement News

ASTM International’s concrete and concrete aggregates committee (C09) is developing a proposed standard specification for a broad range of supplementary cementitious materials (SCMs) in the USA. According to ASTM International member Larry Sutter, this performance specification (WK70466) will ease the adoption of new materials used for SCMs as established sources become less available. “For a variety of reasons, historic sources of SCMs, like coal fly ash from electric power generation, a...

Carbon Upcycling receives SCM project investment funds

01 May 2023, Published under Cement News

Carbon Upcycling and the National Renewable Energy Laboratory (NREL), funded by the US Department of Energy, has been awarded international funding to advance carbon utilisation technology in the cement and concrete industry. The CAD$600,000 (US$442,102) investment will support the development of a framework that will assess the suitability of various alternative feedstocks to produce supplementary cementitious materials (SCMs) in North America, including biomass, low-grade steel slags,...

Collaboration and circular economy building

09 December 2022, Published under Cement News

This week Vicat announced that it was collaborating in a new consortium of manufacturers called the 'Advancement of Excellence in Industry' to advance decarbonisation, the circular economy, the factory of the future and the digital transition. To this end, it will construct a regional campus in Auvergne-Rhone-Alpes. A key insight behind the initiative is that building circular economies can only succeed through collaboration, therefore more partnerships will need to be formed to achieve n...

Solidia Technologies® receives US DoE grant for CCUS and SCM research

26 May 2022, Published under Cement News

Solidia Technologies ® has unveiled plans to widen applications of low-carbon manufacturing technologies for building materials, with support of a US$2.1m grant from the US Department of Energy (DoE). The New Jersey-based firm wants to use its new funds to develop processes for producing synthetic supplementary cementitious materials (SCMs) through direct capture and the utilisation of CO 2  from the flue gas stream of an operating cement plant. It is hoped Solidia will develop an ...

Lehigh Hanson partners with Fortera to reduce carbon emissions

15 March 2021, Published under Cement News

North America's Lehigh Hanson (HeidelbergCement) and Fortera Inc have announced a collaboration project to reduce emissions from Portland cement production. The two companies will work together to construct and operate a small commercial plant at Lehigh's cement facility in northern California. The plant will capture CO 2 from the kiln exhaust and convert it into a cementitious material. This can then be blended with Portland cement and used by ready-mix concrete producers as an SCM or us...

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 ...

New supplementary cementitious materials

19 August 2019, Published under Cement News

The search for new supplementary cementitious materials (SCMs) is ongoing. A recent review of existing SCMs and the potential for new ones caught the eye of Arthur Harrisson and provided further potential for investigation. A disused slate quarry: a potential SCM? A recent review 1 of the availability of supplementary cementitious materials (SCMs) and the possibility for expanding the choice of those available examined the range of emerging SCM sources and also the means of tes...
