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.
