This lesson explains the tests for measuring the workability of concrete. It includes slump test, compaction factor test, flow table test, Kelly ball test and vee bee consistometer test.
Standards. ASTM C1362. General Description. The Concrete Pocket Penetrometer is used for the determination of setting time of fresh concrete. Stainless steel plunger has 32.3 mm² (1/20 in²) area and 0-5 MPa measuring range.
Sep 19, 2010 · The Kelly ball test provides an indication of yield stress, as the test essentially measures whether the stress applied by the weight of the ball is greater than the yield stress of the concrete (Ferraris 1999). For a given concrete mixture, the results of the Kelly ball test can be correlated to slump.
Grieb and Marr made the following comments on the Kelly ball test as a replacement for the slump test to measure the consistency and uniformity of concrete in the field: 1. The concrete may be tested in place, therefore, the selection or preparation of a sample is eliminated.
Test Summary Vibrating Kelly Ball Test (V-Kelly Test) Test AASHTO TP 129 Objective Examine workability and response to vibration of a concrete mixture Time to Complete Test 10 minutes Equipment A ¾ in. vibrator is attached to a 6 in. diameter hemisphere, together weighing 30 lbs.
The Kelly Ball test is a simple field method for determining the consistency of plastic concrete. It is made by measuring the penetration of a 30-pound metal "ball" into the surface of the concrete. This test can be made on the concrete in place and can be made easier and faster than the slump test.
