This material is similar to Portland cement as it binds masonry together stronger and cures faster than plain mortar that is made of sand, quicklime powder and water. He also studies the largest dome structure at the time, the Pantheon, built between 118 and 128 AD and spans 142’. Among other Roman buildings and ruins he also studied the eight sided dome structures, such as the Domus Aurea, Nero’s “Golden House” with a 35’ diameter dome. http://architecture-as-space.info/inspired/Florence_the_Dome... Pozzolith, the Roman concrete, as used in the dome of the Pantheon http://www.filepie.us/?title=Baroque_architecture_in_Portuga... POZZOLITH STANDARD is a powerful plasticizer which deflocculates and disperses the cement particles within a concrete mix. It can be used to improve workability, without the addition of extra water, or to allow reductions in the free water content of the concrete mix. http://www.saudi-basf.com/en/products/Admixturesforconcrete/... -------------------------------------------------- Note added at 3 days4 hrs (2010-05-15 18:46:05 GMT) Post-grading -------------------------------------------------- You are welcome! |
