Modeling The Cementitious Effect Of The Pozzolana On

isolate the effect of Pozzolana from that of cement, two series of batches were formulated for 350 and 400 kg amount of cement of per cubic meter, with a successive increase of the Pozzolana by a rate of 2.5 of the cement weight. Regression analysis was performed that relates the compressive strength versus the Pozzolana rates tested.isolate the effect of Pozzolana from that of cement, two series of batches were formulated for 350 and 400 kg amount of cement of per cubic meter, with a successive increase of the Pozzolana by a rate of 2.5 of the cement weight.
