Australia: Alternative cement and concrete producers have welcomed a new Australian civil engineering standard that allows builders to use reduced-CO2 geopolymer concrete in infrastructure projects. Wagners, which produces Earth Friendly Concrete (EFC), said that the revision has removed one if its key barriers to wider market acceptance. EFC replaces 100% of cement with supplementary cementitious materials, including ground granulated blast furnace slag (GGBFS) and pulverised fly ash, by virtue of its binder technology. Wagners previously supplied EFC for the London Power Tunnels project in the UK, based on local technical approval-based building codes. The producer now expects a new standard like the Australian one to follow in the EU.
Canada: The city administration of Langford in British Columbia plans to enact regulations requiring all public and private projects to use reduced-CO2 concrete. It plans to support the rules with parallel measures affecting the design of buildings.
Victoria News has reported that the city authorities previously mandated reduced-CO2 cement for all projects in June 2022, but subsequently relaxed the regulations after only one company – Butler Concrete and Aggregates – completed the transition. Butler Concrete and Aggregates produces its reduced-CO2 concrete using slag cement supplied by Lafarge Canada.
