>Lightweight Aggregate Concrete

Lightweight aggregate concrete is prepared by using lightweight aggregate or low density aggregate such as volcanic pumice, clay, slate, shale, scoria, tuff and pellite. Concrete is considered to be lightweight is the density is not more than 2200 kg/m 3, when compared to normal concrete which is kg/m3 and a proportion of the aggregate, should have a density of less than 2000 kg/m 3 .

>Pumice and Concrete: Lightweight Insulating Concrete

The Romans employed lightweight pumice concrete in many of their structures—the most famous is the dome of the Pantheon, which remains to this day the world's largest unreinforced concrete dome. Finegrained pumice dust was also used by the Romans as the pozzolanic alyst that made their hydrated limebased concrete ( opus caementicium ) so enduring.
