PyroGenesis Announces That Lab Strength Tests Achieve 45% Above Target for Green Cement Additive Product - Seite 2

All four batches of mortar cubes will also undergo 28-day SAI tests with the results being available sometime after April 29, 2024.

As further stated in Progressive Planet’s news release, concrete producers want SCMs that (i) increase the compressive strength of their mix while (ii) lowering their carbon footprint without sacrificing workability. The workability of cement is measured by water demand. The water demand for PozPyro was between 99% and 109% with the average water demand being 103.75%.

The smaller the water demand number, the better the reading. A passing water demand number must be less than 115% of the water demand of the control mix. As such, all four of the test batches also passed the water demand test.

“It is uncommon to see SCMs exceed the 7-day strength of the control Portland, so we are excited to see better strength while concurrently possessing excellent water demand numbers” said Steve Gurney, President of Progressive Planet.

Crystalline silica is one of the most abundant materials in the earth’s crust and the ability to economically convert it into amorphous silica would offer a new supply of material to compensate for the diminishing supply of fly ash, as coal fired power plants (which generate fly ash) are targeted for shut down in Canada by 2030.

PyroGenesis’ involvement in developing PozPyro from quartz is part of PyroGenesis’ three-tiered solution ecosystem that aligns with economic drivers that are key to global heavy industry. PozPyro is part of PyroGenesis’ Commodity Security & Optimization tier, where the recovery of viable metals and the optimization of production to increase output helps to maximize raw materials and improve the availability of critical minerals.
