The Greek-Roman rock-cut tombs at Alexandria, Egypt, were excavated mainly in the calcarenitic limestone formations and show varying degrees of damage of rock pillars and ceilings. In order to understand the long-term rock mass behaviour in selected tombs and its impact on past failures and current stability, uniaxial and triaxial Creep tests and rock mass quality assessments had been carried …

intraclastic chalk, limestone clasts, impure porcellanite, and siliceous mudstone. In Subunit 2b, there is a repeat-ed interval of intraclastic chalk, with one 4-m interval of siliceous mudstone near the top of the subunit and thin-ner intervals of calcareous mudstone lower in the sub-unit. The base of the chalk turbidite at the top of this

Limestone is sometimes partly formed of coral, in fragments or in reefs. Fossils are plentiful in limestone, particularly those of shell-fish, the shells of which sometimes form the greater part of the stone. The hardness of limestone is close to that of calcite (for which H=3) of which it mostly consists. Its specific gravity is from 2.7 to 2.9.
