Calcined clays (commonly referred to as metakaolin when derived from kaolinite-rich feedstocks) are rapidly emerging as a key pathway for reducing the embodied carbon of cement and concrete systems. Lower activation temperatures, the absence of limestone decarbonation, and strong performance as supplementary cementitious materials (SCMs) have positioned calcined clays as a promising alternative to conventional clinker. However, translating this potential into consistent, comm

Industrial by-products are not static materials. They evolve. In recent work turned peer-reviewed study published in Materials Today Communications, we investigated how Western Australian fly ash sourced from the same region changed composition over a 15-year period - and how those changes altered binder composite performance. Feedstock characterisation is not a one-off exercise. It must be continuous...read more

The Reformix team attended and presented at Concrete 2025, a conference that made one trend unmistakable: The industry is moving decisively toward high supplementary cementitious material (SCM) replacement and alternative binder systems. The good news? Reformix has already been working in this space for years...
