Unconfined Compressive Strength Test - UTA

A commercially available point load test apparatus was purchased and used in a testing program on NX cores from the major types of sedimentary rock found in Missouri. Point load testing was performed in both axial and diametral orientations with unconfined compression tests performed for correlation.

What Is a Point Load? | Reference.com

Definitions, Objectives and Applications Objective To determine the unconfined compressive strength (q u) of the soil Significance • A quick test to obtain the shear strength parameters of cohesive (fine grained) soils either in undisturbed or remolded state • The test is not applicable to cohesionless or coarse grained soils • The test is strain controlled and when the soil sample is ...

Unconfined Compressive Strength Test - UTA

Richardson (1989) conducted a point load tests of cast specimens with various diameters as 50.8, 76.2 and 101.6mm. The advantages of using the point load test relate to a smaller cost per unit test when compared to compressive strength testing of concrete cores and to the speed with which the test can be performed. Testing large

I would just take a 2.5m wide design strip and design the slab with the machine weight as a point load acting central to the 600mm. Alternatively, you can look into a method of finding a 'contributing width' that will flexurally resist point loads, as detailed in AS3600 (Aus). Reference material found below.

POINT LOAD STRENGTH INDEX TEST OF ROCK (IS-8764 ...

First, the point load test is a relatively cheap test, as the system required to perform the test is not very large or complicated. The point load test does not require specialized specimen preparation, thus eliminating the need for other expensive equipment in order to prepare a specimen.

Correlation between the point load index (Is(50)) and the ...

The point-load test in geotechnical practice - ScienceDirect

The Point Load Test (PLT) allows us to determine the Point Load Resistance Index or Point Load Strength, (I s(50)). It is useful in classifying rocks by their resistance. Ever since its emergence, Franklin and other researchers have proposed a correlation with UCS [5], but this value ´ ´ 36.

The point-load test in geotechnical practice. Eng. Geol., 9: 1--11. The point-load test is evaluated for practical applications in engineering geology. The three variations of the test, i.e., diametral, axial and irregular lump are assessed and it is found that the diametral point-load test …

THE POINT-LOAD STRENGTH TEST - ResearchGate

The estimated point-load strength values of specimens of varying sizes and also the values corrected to a standard thickness of 50 mm, and the resultant point-load strength values (Is-50) have been used to estimate the uniaxial (unconfined) compressive strength which correlates well with actual recorded uniaxial (unconfined) compression test ...

STRENGTH CLASSIFICATION OF GRANITE USING POINT LOAD TEST ...

Jun 28, 2010· Distributed loads - You would need to fit a fourth order curve to deal with distributed loads directly, but you could convert the distributed load to a point load and a moment at each loaded node position, then use the same method with a cubic spline by applying a unit rotation as well as a unit deflection at the load positions.

Point Load on Slabs - Structural engineering general ...

Summary. Point-load tests were performed on three hard rocks of the Lake Superior district, ironformation, metadiabase, and ophitic basalt. More than 500 irregular, mine-run fragments ranging in diameter up to about 250 mm were tested in the field, using a specially designed, semi-portable test rig.

such as the point load test can be used in the field to reduce the time and cost of compressive strength tests. 5.2 The point load strength test is used as an index test for strength classification of rock materials. The test results should not be used for design or analytical purposes. 5.3 This test method is performed to determine the point

Load testing lets you measure your website's quality of service (QOS) performance based on actual customer behavior. Nearly all the load testing tools and frame-works follow the classical load testing paradigm: when customers visit your web site, a script recorder records the communication and then creates related interaction scripts.
