| Abstract: | The coralline limestone covers large areas in the western and northern parts of Jeddah City. This coralline limestone is composed mainly of shelly limestone with pencil-sized animal borings. These borings increase the primary porosity and make the rock weak enough to have low-bearing capacity. The dry density (γ dry) values of the study coralline limestone ranges from 1.54 to 2.09 g/cm3. The total porosity varies from 12.34 to 28.42 %. The absorption percentage fluctuates between 6.49 and 17.75 %. More than 95 % of the tested rock core samples have compressive strength less than 15 MPa. The compressive strength commonly decreased with the increase of animal borings. The obtained results cause the study coralline limestone weak enough to support heavy structures. |
