Natural stone suppliers is a reputed India based company engaged as suppliers and exporters of high quality natural stones such as Indian natural stones, marble, sandstone, limestone and a variety of other construction and natural building stones, for discerning buyers around the globe.
Mechanical properties of rock. Mechanical properties include: Elastic properties (Young's modulus, shear modulus, bulk modulus, and Poisson's ratio) [See Stress strain relationships in rocks for calculations of these properties]; Inelastic properties (fracture gradient and formation strength)
with limestone masonry. The work was carried out in order to make a structural assessment of a gothic construction built in the center of Paris in the 13th century (Old Refectory of the Saint-Martin des Champs priory – 1230) (Fig. 1). The structural analysis of this monument required the mechanical properties of the limestone masonry to be known.

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.
Limestone has been used as a partial substitute for cement, due to its beneficial effect on mechanical properties of mortars and concretes. In the present research, we studied the effect of the mineralogical composition in mortars produced from limestone samples collected in different areas of Mozambique, using two cement types (Portland cement 32.5N and 42.5N).
