3-Story Residential Building: First Ever Cement-Free Concrete Pour in Canada
June 2024 Toronto area, ON
June 2024, C-Crete was poured in a three-story, ground-up residential building near Toronto, which marks the first-ever application of cement-free concrete in Canada. The project, totaling ~500 cubic yards, began with 60 cubic yards placed for the footings, with the remainder designated for walls, columns, slabs-on-deck, driveways, and more.
Unlike the United States, Canada currently lacks a direct counterpart to ASTM C1157 for cement-free concrete. Nevertheless, the building owner, Trevor, helped break new ground by referencing the closest equivalent Canadian standard—developed with input from C-Crete – and successfully persuaded both the building inspector and structural engineer to proceed. His initiative has effectively laid the foundation for broader adoption of low-carbon concrete in the country.
With Canada’s demanding winter climate, this project offers a valuable opportunity to validate the long-term durability of C-Crete under extreme conditions.
The C-Crete concrete achieved a 28-day compressive strength of >5000 psi, confirming its ability to deliver structural-grade performance without relying on Portland cement. This milestone reinforces the promise of C-Crete as a low-carbon, high-strength alternative to conventional concrete – one capable of enduring Canada’s harsh winters while dramatically reducing embodied CO₂ emissions.
