...). Pozzolanic crystallization of Al-tobermorite, a rare, hydrothermal, calcium-silicate-hydrate mineral with cation exchange capabilities, has been previously recognized in relict lime clasts of the concrete. Synchrotron-based X-ray microdiffraction maps of cementitious microstructures in Baianus Sinus...

... pozzolanic aggregate (pulvis puteolanus), and quartz-feldspar sands (present as crystal-clasts with an almost constant ratio of about 2:1, respectively). The cocciopesto is anomalously rare or absent. In the mortars local dacitic volcanic rock were also used, especially in the concrete as caementia.The grey...

... of alumina-rich volcanic ash. This notably unique combination formed the fundamental cementitious binding component, the glue, which, when mixed with pozzolanic coarse aggregates of zeolitic tuff, composed a unique concrete mixture that could set quickly under seawater, become extremely strong, and remain...

... or pozzolans are abundant in certain locations and are extensively used as an addition to Portland cement in countries such as for example Italy, Germany, Greece and China. Compared to traditional industrial SCMs they are characterized by a larger range in composition and a larger variability in physical...

... for the control composition due to the fact that clinoptilolite exhibits its pozzolanic activity later in the hydration. In these later stages, pores with radii below 500 nm increased at the expense of larger pores. The change in the pore-size distribution between the first and sixth months of hydration occurs...
