Some Useful Numbers on the Engineering Properties of Materials (Geologic and Otherwise) GEOL 615 Coefficient of sliding friction ( ) For most rocks, varies between 0.8 and 0.5. A value of 0.60 would be a good number for general use. Glass on glass 0.4 Rubber on concrete 0.75 Steel on steel 0.55 Angle of internal friction ( Rock 30
Full knowledge of the physical and mechanical behavior of limestone rocks is required for the safe design of structures. Little work has been done to characterize the physical and mechanical properties of Jordanian limestone especially under watery environment. Therefore, in this study the physical and mechanical properties of some Jordanian limestone were investigated.

In considering the engineering geology of this limestone, as an engineering material, its relevant physical and mechanical properties have been assessed;
This paper presents the geotechnical properties of young calcareous rocks of southern Florida. The rocks covered are Miami, Key Largo, and Fort Thompson limestones. The paper briefly details the formation and areal extent of the rocks and then evaluates several samplers for obtaining maximum recovery in a relatively undisturbed form.

This paper is concerned with the mechanical properties of the Great Limestone in northern England. After first outlining the geological structure of the limestone at East Layton in north Yorkshire, the problem of the basal dolomitization of the limestone is introduced and the geochemistry of the rock profile evaluated.
Apr 25, 2017· AppearanceGranite has a grainy appearance and can be pink or varying shades of gray, depending upon its chemical and mineral make-up. The rock is usually found in large deposits; for example, those that form large massifs or tors. Limestone is mainly white, although it may be tinted by impurities. The presence of iron oxide, for example, gives it a brownish or yellowish tint, and carbon .
