Physical and mechanical studies on binary blended Portland cements containing mordenite-rich tuff and limestone filler

Résumé

In this research, we made physical and mechanical analyses thanks to which we deduced that the potential of replacing the Portland cement up to 20% by modernite-rich tuff (TM) and limestone filler (LF). The experimental procedure was done in two main stages. The first stage was dedicated to the pastes, including water requirement, setting time, hydration heat and free Ca(OH)2 content. In the second stage, mechanical and physical properties of mortars, water porosity and pore size distribution were studied. The final results show that LF mixtures closest to the control mixtures unlike the MT mixtures which exhibited a high water demand, less free Ca(OH)2, rapid appearance of the maximum thermal effect, an increase in the total and water accessible porosity, there is also a delay in improving of strength.
