Estimating Unconfined Compressive Strength of Sedimentary,

4. Point Load Test The ASTM-D5731-08 [8] code gave a clear justification for the use of the point load test. The code started its justification by giving statements about the time and money spent on performing a UCS test and recommended the use of simpler in-situ tests of which the point load test was one of them. The code also stated that this,8. STRENGTH OF SOILS AND ROCKS - MSE - MyWebPages,separation between the platens, the point load strength index (I s) is defined as IS = P/D 2 (8.4) Corrections are applied to I S to allow for specimen size and shape to yield the size corrected point load strength index (I S50) which is defined as the value of I S for a diametral test with D equal to 50mm.Estimation of uniaxial compressive strength of,This apparatus is designed to fit into the existing point load test frame. The specimen was placed at the centre of the base support and fastened symmetrically along the punching canal with the help of a clamp. It was then vertically loaded by the punch block hydraulically controlled by the point load device.

Laboratory Testing and Interpretation of Rock Properties

8.2 LABORATORY TESTS Common laboratory tests for intact rocks include measu rements of strength (point load index, compressive strength, Brazilian test, direct shear), stiffness (ultrasonics, elastic modulus), and durability (slaking, abrasion). Table 8-1 gives a summary list of laboratory rock tests and procedures by ASTM. Brief sectionsPortable Point Load Test Apparatus - APS - Wille,Portable Point Load Test Apparatus. The portable point load tester provides an index for the strength classification of hard rocks and allows for a quick, non-expensive on-site evaluation of hard rock strength. A sample of rock is mounted between two pointed platens. Pressure is then applied until failure (breakage) of the sample occurs. The peak-applied load is recorded and used to calculate,AMERICAN SOCIETY FOR TESTING AND MATERIALS Reprinted,5.3 This test method is performed to determine the point load strength index (Is(50)) of rock specimens, and the point load strength anisotropy index (Ia(50)) that is the ratio of point load strengths on different axes that result in the greatest and least values. 5.4 Rock specimens in

Uniaxial Compressive Strength - an overview,

Uniaxial compressive strength (UCS) is a key physical test relevant to iron ore crusher design and rock geomechanics for mining. Tests are typically performed on intact lengths of NQ, HQ, or PQ diamond drill core and record the maximum axial load sustained at the point of failure.Point Load Test Results from Olkiluoto Area Borehole Cores,tests are not as accurate as laboratory tests but they are a quick and cost-effective way to determine the rock properties over a large volume of rock.
