From a different source (5) the crushing strength of Coral limestone is given as 75N/mm2 (11,000 lbf/ in2). From tests carried out by W. Debattista (6) on local mortars the commonly used cement mortar mix having proportions 1:2:10 of cement, to coralline limestone sand to fine globigerina sand had an average crushing strength at 28 days of
This specification provides the basis for five different mortar types (Type K is listed in section X3 of the appendix) depending on the strength of mortar needed for an application. The names for these mortar types, developed in 1954, were based on alternating letters of the phrase "MASON WORK". Type M mortar has the highest strength.
compressive strength is then defined as the maximum load applied to crush the specimen divided by the crosssectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig.
