Canada: Progressive Planet Solutions has successfully produced a new supplementary cementitious material (SCM) called PozDE from diatomaceous earth. The company says that it developed PozDE using calcium bentonite-containing diatomaceous earth from the Red Lake mine in Kamloops, British Colombia. The SCM’s seven-day and 28-day strength activity index (SAI) values are 101% and 120% those of ordinary Portland cement (OPC) respectively, while its water demand is lower at 98%.

Chief operating officer Ian Grant said “It is uncommon to see SCMs exceed the 7-day strength of the control Portland, so we are excited to see better strength while indicating lower water demand."
