Prediction of uniaxial compressive strength of granitic
When compared with weak rocks, the number of studies on the prediction of uniaxial compressive strength of granitic rocks due to its high strength nature is low. The accurate determination of uniaxial compressive strength (UCS) plays a vital role in the initial design phase of rock engineering and rock geotechnics.

The sensitivity of mechanical properties and pore structures
It can also be seen from Figs. 7 and 10 that the uniaxial compressive strength and porosity of granite are function of temperature. Therefore, in order to measure the thermal damage caused by temperature, porosity and uniaxial compressive strength are selected to define damage variables. The calculation formulas are as follows:Rock abrasivity index (RAI) and uniaxial compressive strength (UCS) are two key parameters for assessing abrasivity and durability of building stones, respectively. Direct determination of these parameters is a time-consuming, tedious and costly task. Hence, indirect and nondestructive tests such as P-wave velocity (Vp) and Prediction of Rock Abrasivity Index (RAI) and Uniaxial Compressive

Effect of Defects on Uniaxial Compressive Strength and Point
Uniaxial compressive strength (UCS) and point load strength (PLS or Is(50)) are fundamental mechanical parameters in rock engineering. Investigating the relationship between UCS and PLS is also one of the important research contents in rock mechanics, however, the relationship is usually complex and changeable. This paper Basalt was used as an ornamental stone in any historic and ancient cities in Jordan. Measuring the uniaxial compressive strength (UCS) and the tangent Young’s modulus (Et) in the laboratory requires premium quality specimens with special core dimensions.
