Point load strength index of granitic irregular lumps

01/11/2017· This paper presents the methodology for specimen preparation, testing, and data analysis. Results from irregular lump point load tests, diametral and axial point load tests, and uniaxial compressive tests (a total of 754 specimens of granitic rocks were tested) are then presented, analyzed, and discussed. A correlation between PLSI from irregular lump tests and UCS is

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 been proposed

USING THE POINT LOAD TEST TO DETERMINE THE UNIAXIAL

The point load test (PLT) is an accepted rock mechanics testing procedure used for the calculation of a rock strength index. This index can be used to estimate other rock strength parameters. The focus of this paper is to present the data analysis used to correlate the point load test index (Is50) with the uniaxial compressive strength (UCS), and to propose appropriate Is50 to UCS conversion

Point Load Test

The point load test does not require specialized specimen preparation, thus eliminating the need for other expensive equipment in order to prepare a specimen. This test is also relatively rapid and yields a test result rather quickly. This allows for quick, informed decisions to be made. Also, this test can be performed in the field, thus enhancing efficiency. Although the point load test can

Determination of Tensile Strength and Fracture Toughness

In this study, granite is chosen as an example to show how the tensile strength and fracture toughness can be measured from small three-point-bend samples of a single size but with different notches. An existing fracture mechanics model has been extended to include the stable fictitious crack growth before peak loads, which is then linked to the granite grain size. Both tensile strength and

STRENGTH PROPERTIES OF ROCKS AND ROCK MASSES 1

Broch and Franklin (1972) proposed a testing method called the Point Load Test. The test consists of squeezing pieces of rock diametrically between two hardened steel cones. The test set-up is shown in Figure 1. For these tests, rock pieces must have a length at least 1.4 times their diameter (Figure 2a). The point load index, Id, is equal to
