  • Natural Pozzolans an overview ScienceDirect Topics

    Among s with a natural origin, we can distinguish natural pozzolans which do not need to be treated to react with calcium hydroxide, and those which need an activation to react with calcium hydroxide and that we could call artificial pozzolans. The so-called natural pozzolans, used as s for the production of pozzolanic cements, are pyroclastic rocks rich in silous or silous and aluminous volcanic .
