Chat Online### The effect of length to diameter ratio of test specimens

· One of the parameters which affect the uniaxial compressive strength (UCS) of rock materials is the length to diameter ratio (L/D) of test cores. ASTM recommends a ratio of between 2 and 2.5 and ISRM suggests 2.5–3 1. Research has shown that high UCS values are obtained for L/D ratios <2 a very slight difference in values between 2 and 2.5 and they remain effectively constant with a
