A Correlation Equation on the Influence of Length to Diameter Ratio on the Unconfined Compressive Strength of Lateritic Rocks in Goa
Rock materials with unconfined compressive strength (UCS) less than 20 MPa are termed as soft rocks. The factors on which UCS may depend are shape and size of specimen, rate of loading, degree of saturation and so on, which are termed as external factors, while defects, porosity, mineralogy and degree of weathering are termed as internal factors. One of the parameters which affect the unconfined compressive strength (UCS) of rock materials is length to diameter ratio (L/D) of test cores. In this study, the shape effect on the UCS of lateritic rock was investigated. A number of unconfined compression tests have been conducted onto the lateritic rock samples from Pernem site in Goa with different L/D ratios. An equation is proposed for the correction of unconfined compressive strength test results to a length to diameter ratio. The results obtained by this equation are compared with previously published equations for correction of unconfined compressive strength.
