Physical properties and reactivity of pozzolans, and their …
This paper studies how pozzolan properties including particle size, specific surface, chemical and mineral composition, amorphousness and water demand, affect their reactivity as well as the strength of lime–pozzolan pastes. Reactivity was evaluated with chemical, mechanical and mineralogical methods. A number of artificial pozzolans were …
Characterization of moist pozzolana: stability and flow
Pozzolana grains used in the experiments come from San Carlos in the province of Mendoza, Argentina, and are mainly composed of quartz with no significant water absorption. Grains are quite irregular (Fig. 1 a) and, after sieving, 22 and 16% of the total mass were retained by the R175 (90 μm) and R325 (45 μm) mesh sieve, respectively.
