A:The Greeks used volcanic tuff from the island of Thera as their pozzolan and the Romans used crushed volcanic ash (activated aluminium silicates) with lime. This mixture could set under water, increasing its resistance to corrosion like rust. The material was called "pozzolana" from the town of Pozzuoli, west of Naples where volcanic ash was extracted. In the absence of pozzolanic ash, the Romans used powdered brick or pottery as a substitute and they may have used crushed tiles for this purpose before discovering natural sources near Rome. The huge dome of the Pantheon in Rome and the massive Baths of Caracalla are examples of ancient structures made from these concretes, many of which still stand. The vast system of Roman aqueducts also made extensive use of hydraulic cement. Roman concrete was infrequently used on the outside of buildings. The normal technique was to use brick facing material as the formwork for an infill of mortar mixed with an aggregate of broken pieces of stone, brick, potsherds, recycled chunks of concrete, or other building rubble. B:Would a visitor to ancient Roman ruins that can only be viewed from a distance likely see Roman concrete? Answer: peas
A:Smith's career was cut short by the Great Depression, which nearly put the recording industry out of business, and the advent of sound in film, which spelled the end of vaudeville. She hardly stopped performing, however. The days of elaborate vaudeville shows were over, but Smith continued touring and occasionally sang in clubs. In 1929, she appeared in a Broadway musical, "Pansy". The play was a flop; top critics said she was its only asset. B:Was Smith in any performances after films had sound? Answer: of
