Experimental Investigation on Uniaxial Compressive Strength of

The uniaxial compressive strength (UCS) of sandstone is an important mechanical property with regard to buildings [ 12, 13 ]. Experimental studies have demonstrated that UCS primarily varies according to the mineralogy and microstructure of the material. The elastic modulus and UCS are fundamental mechanical properties of rocks.

The criterion of failure of a limestone is given by (in MPa): SIZE EFFECT ON COMPRESSIVE STRENGTH. It has been found through experimentation that rock strength is affected by the SIZE of the specimen tested. This can be explained simply as being the result of the many flaws found in rock in the form of fissures, pores, cleavage, bedding
