Australia: First Graphene has partnered with Suvo Strategic Minerals to develop graphene-enhanced metakaolin for use in cement and concrete production. Metakaolin is a pozzolanic material derived from kaolinite clay. The partners believe that the technology has commercial potential to improve concrete performance and reduce CO2 emissions.
Portugal: Researchers at the Department of Materials Engineering and Ceramics at the University of Aveiro have developed a so-called ‘eco-cement’ that uses waste cellulose and clay. The cement type uses waste from the pulp industry such as ash and lime grains. This makes up 70% of its composition with the remaining 30% being metakaolin clay. The cement can be manufactured at room temperature reducing its energy consumption massively compared to Ordinary Portland Cement. The research team includes Manfredi Saeli, Rui Novais, Paula Seabra and João Labrincha.
Hoffmann Green Cement Technologies pilot plant to start commercial production in 2019
03 October 2018France: Hoffmann Green Cement Technologies’ pilot plant at Bournezeau, Vendée is set to start commercial production of low-carbon cement products in January 2019. Construction of the 50,000t/yr unit is due to be completed in October 2018 with its inauguration scheduled for late November 2018, according to Batiactu. The plant will employ 10 workers initially and this will rise to 15 – 20 as production ramps up.
The producer intends to make cement products using metakaolin and blast-furnace slag. If the pilot plant is a success it then intends to raise funds to build a 0.5Mt/yr plant.
