BS 5930 (1981) provides no help for engineers wishing to take advantage of the quick, cheap rock strength assessment provided by the point load test introduced in 1972. The paper discusses the correlation factors obtained as a result of testing the same material from the Corallian strata at Weymouth by point load and uniaxial compression. The considerable advantage obtained using the point ...

USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL ...
Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate uniaxial compressive strength, index-to-strength conversion factors are used. These factors have ...

Weight (Mass) Conversion Calculator
By knowing the conversion factor, converting between units can become a simple multiplication problem: S * C = E. Where S is our starting value, C is our conversion factor, and E is our end converted result. To simply convert from any unit into grams, for example, from 5 kilograms, just multiply by the conversion value in the right column in ...

Dimensions, Units, Conversion Factors, and Significant Digits
Dimensions, Units, Conversion Factors, and Significant Digits . Introduction ; There is a difference between dimensions and units. A dimension is a measure of a physical variable (without numerical values), while a unit is a way to assign a number or measurement to that dimension.; For example, length is a dimension, but it is measured in units of feet (ft) or meters (m).

The estimation of uniaxial compressive strength .
The point load (PL) test is generally used for estimation of uniaxial compressive strength (UCS) of rocks because of its economic advantages and simplicity in testing. If the PL index of a specimen is known, the UCS can be estimated using conversion factors. Several conversion factors have been proposed by various researchers and they are dependent upon the rock type.
