2. Pozzolan - Wikipedia

   en.wikipedia.org/wiki/Pozzolan

   Both natural and artificial (man-made) materials show pozzolanic activity and are used as supplementary cementitious materials. Artificial pozzolans can be produced deliberately, for instance by thermal activation of kaolin-clays to obtain metakaolin , or can be obtained as waste or by-products from high-temperature process such as fly ashes ...

3. Pozzolana - Wikipedia

   en.wikipedia.org/wiki/Pozzolana

   Pozzolana from Mount Vesuvius volcano, Italy. Pozzolana or pozzuolana (/ ˌ p ɒ t s (w) ə ˈ l ɑː n ə / POT-s(w)ə-LAH-nə, Italian: [potts(w)oˈlaːna]), also known as pozzolanic ash (Latin: pulvis puteolanus), is a natural siliceous or siliceous-aluminous material which reacts with calcium hydroxide in the presence of water at room temperature (cf. pozzolanic reaction).

4. Hydraulic lime - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_lime

   Hydraulic lime concretes have been in use since Roman times, either as mass foundation concretes or as lightweight concretes using tufa or pumice as aggregates and a wide range of pozzolans to achieve different strengths and speeds of set. This meant that lime could be used in a wide variety of applications including floors and even vaults or ...

5. Cement - Wikipedia

   en.wikipedia.org/wiki/Cement

   Portland pozzolan cement includes fly ash cement, since fly ash is a pozzolan, but also includes cements made from other natural or artificial pozzolans. In countries where volcanic ashes are available (e.g., Italy, Chile, Mexico, the Philippines), these cements are often the most common form in use.

6. Energetically modified cement - Wikipedia

   en.wikipedia.org/wiki/Energetically_modified_cement

   However, adding high-reactivity pozzolans into the concrete mix prevents such a conversion reaction. [66] In sum, whereas pozzolans provide a number of chemical pathways to form hardened materials, "high-reactivity" pozzolans such as blast furnace slag (GGBFS) can also stabilise certain pathways. In this context, EMCs made from fly ash have ...
