Pumice and Concrete: Pumice and Roman Concrete

Pumice and Roman Concrete. Some two thousand years after the Romans built it, the dome of the Pantheon is still the world's largest unreinforced concrete dome. The concrete mix design Roman engineers figured out stands as a historically impressive architectural feat. Their empire—temples, roads, aqueducts, piers, arenas—was built from this impressive concrete. 2000 years later: those ...

About Pumice: Origins, Applications, Chemical Makeup

Fortunately, when it comes to concrete, pumice makes an incredibly useful pozzolan (the Roman word for pumice was “pozzolana”), and pozzolans do wonderful things to enhance and improve standard concretes. So, replacing part of the Portland Cement power with pumice powder (pozzolan), significantly moves the green needle on the concrete while imparting incredible high-performance ...

The Pumice Store: Performance-Enhancing Concrete Pozzolan

Pozzolans are a class of supplemental cementitious materials that supercharge concrete performance. Pumice, in particular, is an excellent pozzolan. Used at a 15 to 20% replacement rate for Portland cement, the finely ground pumice pozzolan works to drastically reduce, even eliminate, by-product CH by coverting it to CSH. More CSH means more binder. That means more density in the concrete ...

Roman concrete - Wikipedia

Roman concrete, also called opus caementicium, was a material used in construction in Ancient Rome. Roman concrete was based on a hydraulic-setting cement. It is durable due to its incorporation of pozzolanic ash, which prevents cracks from spreading. By the middle of the 1st century, the material was used frequently, often brick-faced, although variations in aggregate allowed different ...
