Universities research rice husk ash as cement alternative09 July 2024, Published under Cement NewsResearchers from ten universities across the globe are exploring the feasibility of using rice husk ash (RHA) in place of cement for manufacturing activities. The participating researchers have found the RHA has a high silica content. Therefore, when RHA is used to produce concrete, it triggers a chemical reaction with hydrates (such as calcium hydroxides). This results in the formation of supplementary products that give the mixture strength and stability, which are vital for the concr... |
Cambridge Electric Cement secures £2.25m for low-carbon cement05 July 2024, Published under Cement NewsA British start-up, born out of the University of Cambridge, has raised GBP2.25m in seed funding to support its plans to industrialise the production of low-carbon cement. Cambridge Electric Cement (CEC) has received investment from previous investor Legal & General, as well as Cambridge Enterprise Ventures, Parkwalk Advisors, Almanac Ventures and Delph25 in a funding round spearheaded by Zero Carbon Capital. The company has announced that it has developed a way to make low-carbon, cir... |
