OTTAWA — EllisDon is reporting it recently completed its first test concrete pour with Bio Graphene Solutions (BGS) and Tomlinson.
The test consisted of a sidewalk pour at one of its projects in Ottawa.
According to a release, in 2023, BGS developed a graphene-enhanced admixture for commercial concrete uses that tackled CO2 emissions by reducing cement, the binding material in concrete mix, which contributes more than eight per cent of global CO2 emissions.
“This trial has removed 10 per cent of the cement content in concrete due to the graphene-enhanced mixture without sacrificing the compressive strength performance of the overall concrete product,” the release reads. “BGS continues to evaluate the opportunity to reduce cement content by up to 20 per cent to understand what can be done without affecting performance or cost.”
EllisDon states these findings will have a direct impact on the construction industry.
“Decarbonizing the construction industry is an all-hands-on deck effort,” said Jolene McLaughlin, vice president, climate and sustainability, EllisDon in a statement. “We’re committed to working with our clients, design partners, and particularly sub trades and suppliers to bring credible and practical low carbon solutions to the market.”
