PETROLOGICAL AND STRENGTH PROPERTIES OF GRANITE IN ,
between the strength parameters of granite Results show that there is significant factor between tensile strength and UCS in a ratio of 1 to 10 Meanwhile, for point load index, I S(50) and UCS correlated, the correction factor is 15, within the range of correction factor determined by other researchers
The Influence of Pre-Existing Deformation and Alteration ,
For example, the PLT to UCS conversion factor can vary from as low as 8 to as high as 30, while the ITS to UCS conversion factor values vary between 27 and 50 [43,44] This implies that the conversion factor is a rock characteristic parameter and not a universal value; therefore, its applicability must be assessed on a case by case basis

USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL ,
relationship between UCS and the point load strength could be expressed as: UCS = (K) Is50 = 24 Is50 (2) Where K is the "conversion factor" Subsequent studies found that K=24 was not as universal as had been hoped, and that instead there appeared to be a broad range of conversion factors Table 1 summarizes published results obtained for .
