MORTAR STUDIES TOWARDS THE REPLICATION OF ROMAN CONCRETE

Archaeometry, 2008
The use of strong and durable materials is one essential ingredient leading to the survival of many monumental Roman concrete structures. Replicated concrete mortars with different lime to pozzolan ratios, encompassing the range likely to have been used by the Romans, have been studied here to determine their relative compressive strengths as a ...

The fracture toughness of an Imperial Roman mortar

Engineering Fracture Mechanics, 2013
Abstract The vaulted concrete monuments of ancient Rome have an unreinforced concrete core of Pozzolanic mortar and decimeter-sized coarse aggregate. An assessment of the mechanical and fracture properties of a reproduced Trajanic-era (c. 100ad) mortar is the subject of the present work.
