RE:RE:Progessive Plan and PyroGenesis

From @cargo (ceo):

@cargo For those that are interested here is an older paper on engineering properties of amorphous silica as a new natural pozzolan for use in concrete. The paper states that amorphous silica has two potential uses in concrete one as a natural pozzolan the other as concrete replacement. Very positive results in the paper when tested in both scenarios. https://www.researchgate.net/publication/223820176_Engineering_properties_of_amorphous_silica_as_a_new_natural_pozzolan_for_use_in_concrete Based on the report natural amorphous silica used in the tests was only about 68.90% amorphous (table 2 average). Very curious if the material $PYR sent to PLAN of the +90% conversion rate what percentage of the material is actually amorphous? IMO If it is over 90% which would be my guess we could see better results. "The Keciborlu amorphous silica rocks generally containmore than 90% silicon dioxide, 68.90% of which are amorphous"

The energy costs of producing nanoparticles were prohibitive, but the use of plasma torches to transform crystalline silica into amorphous silica offered promise.

The contract required Pyrogenesis to deliver 500 grams of converted silica. This material was delivered in early February 2024 and PLAN conducted testing and confirmed that the conversion had occurred with over 90% conversion.

The next step is to confirm that the powder is reactive as a supplementary cementing material (SCM). PLAN has scheduled the production of mortar cubes using the powder during the week of March 4, 2024. Full details of compressive strength and water demand will be released after the 28-day compressive tests are completed. PLAN anticipates releasing these results in the second week of April 2024.

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 fly ash which is no longer being generated from coal fired power plants which are required to shut down in Canada before 2030.

"While this material still needs to prove its merit through compressive strength testing in cement mortars, I wish to acknowledge the effort made by the technical team at Pyrogenesis over the last two years to overcome hurdle after hurdle to reach the conversion rate of over 90%" stated Steve Harpur, CEO of Progressive Planet.
