The field trial of a mineral-based concrete binder as a replacement for portland cement shows promise, says structural engineer Don Davies, the developer of a living laboratory in Seattle to prove the efficacy of bleeding-edge reduced-carbon materials.
The structural engineer-turned-developer showcased C-Crete Technologies’ zeolite-based binder in a 20-ton outdoor slab-on-grade, cast on Nov. 16, at the 5,126-sq-ft Hubbard’s Corner seismic retrofit. Davies is excited about the implications of concrete containing C-Crete’s zeolite binder, which he says was batched from a ready-mix truck, pumped and finished using normal construction procedures.
