03 October 2023, Published under Cement News

C-Crete Technologies is developing a method for using carbon dioxide captured at industrial sources or from the air as an ingredient in its cement-free concrete, in work accelerated by US$2m of funding from the US Department of Energy (DOE). "The DOE funding will help propel C-Crete's already eco-friendly product into the exceptional category of carbon-negative building materials, possibly the first pourable, ready-mix concrete product to achieve this longtime goal of the industry," the c...

The science of carbon removal and carbon sinks

21 July 2023, Published under Cement News

This week Brimstone announced that it had achieved third-party certification of its carbon-negative cement that meets the ASTM C150 standard. Low-carbon and green cements are continuously being developed as alternatives to ordinary Portland cement (OPC). Decarbonising the cement and concrete sectors will need such innovation, but the science of carbon removal from cement and concrete and to what extent they can act as carbon sinks is still a debated subject. While carbon capture, utilis...
