The role of brick pebbles and dust in conglomerates based on hydrated lime and crushed bricks

摘要

Phoenicians were probably the first ones to use mortars based on hydrated lime and crushed or dust bricks, followed by all other people who were in contact with them. The Romans employed those mortars any time they needed a rendering exposed to severe environment or a floor at a very humid ground level, in foundations where the water table was high or for thermal baths. The use of brick dust in a lime mortar is, nowadays, generally interpreted as an alternative to Pozzolana or to other pozzolanic materials.
