PozPyro Strength Activity Index (SAI) %Gain Vs. Portland Cement Table
Compressive Strength (CS) Tests of Cement - Individual Test Results

A comparison of the four individual Series A and Series B strength tests, measured at 7- and 28-days in megapascals (MPa) of a 20% PozPyro/80% Portland Cement blend against a 100% pure Portland Cement control, a 20% fly ash blend, a 20% ground granulated blast-furnace slag (GGBFS) blend, and a 20% silica fume blend produced using traditional methods.
Compressive Strength (CS) Test of Cement - Averaged Result by Test Series

A comparison of the Series A and Series B strength tests, measured at 7- and 28-days in megapascals (MPa) of a 20% PozPyro/80% Portland Cement blend, using averages of each of two tests within both Series A and Series B, against 100% pure Portland Cement control, 20% fly ash blend, 20% ground granulated blast-furnace slag (GGBFS) blend, and 20% silica fume blend.
Comparing CO2 Emission of Cement Additive Production

A comparison of CO2 emitted during the production of 1 tonne of PozPyro vs. other cement additive products. CO2 emission assigned to PozPyro comes from production of electricity subsequently used by the process, not from the process itself.
Conversion of Crystalline Quartz to Amorphous Silica through PyroGenesis’ Plasma Process

A zero-CO2, energy-efficient conversion of crystalline quartz to amorphous silica through PyroGenesis’ plasma process.
