Fly ash is the utmost general pozzolan and is found extensively applied universally in concrete works. It is universally acknowledged that the employment of fine fly ash upgrades the qualities of mortar and concrete [9, 24]. Even though the porosity of the paste is enhanced on account of the inclusion of fly ash, the average pore size gets
A tour of the various concrete infrastructure in and around Rome provides ample witness to the wondrous "eternal" nature of concrete produced as a result of their understanding of how to use a high quality natural pozzolan. The Pantheon, after 2000 years, remains the largest unreinforced concrete dome ever constructed.
