Abstract:
Some ancient types of water conduits-tunnels, arch construction, and pressure conduits-are dealt with. Building materials for lining, concrete, mortar, and plaster based chiefly on lime as binding material as well as a paste for sealing joints in pressure ducts were examined. Experiments were carried- out to imitate an expanding sealant described by Vitruvius. The causes for the great tightness, strength, and resistance of the ancient carbonate concretes were analyzed.
