The Kelly ball test is a test that measure workability of fresh concrete on the construction site. The Kelly ball test method has been developed as a fast alternative to the slump test which is effortless and reasonably priced. This type of test can be executed rapidly and the end result s can then be correlated to slump.
The apparatus consists of a double wooden table measuring 700x700 mm hinged at one side. The top table is covered with an inscribed metal plate 2 mm thick: The steel cone, part of the apparatus, has a top dia. of 130 mm a base dia. of 200 mm and is 200 mm high.
scope: This test method describes the procedure for determining the consistency of fresh concrete by measuring the depth of penetration of a metal mass into plastic concrete under the force of gravity and quantitatively assessing the responsiveness to vibration of dry concrete mixtures, as is desired of a mixture suitable for slipform paving. ...

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.
THE BALL PENETRATION TEST (a.k.a Kelly Ball Test) can be conducted on site by measuring the indentation made by a Kelly Ball into plastic concrete. The device consists of a 6 inches steel cylinder (15cm) in diameter with a semi spherical shaped bottom and 4 5/8 inches in height.
The International Union of Laboratories and Experts in Construction Materials, Systems and Structures (RILEM) was founded with the aim to promote scientific cooperation in the area of construction materials and structures worldwide.
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.
Vibrating Kelly ball (V-Kelly) Test Procedure For additional information, Reference AASHTO T129 Static Test: 1. Sample fresh concrete according to AASHTO R 60 – Sampling Freshly Mixed Concrete. 2. Place concrete in the rubber tub and create a level surface. Do not consolidate the concrete. 3.
and ASTM Designation C 143, "Slump of Portland Cement Concrete. "(1) (2) TEST PROCEDURES AND METHODS 1.) The Kelly Ball Test was used as specified in ASTM C 360 with the exception that single readings were to be recorded. 2.) Modified Ball Test was performed as follows: a.) Device to be held vertical to the surface of the concrete ...
The Kelly Ball test is a simple and inexpensive test that is performed on concrete. It provides an indication of yield stress, and the results of the test can then be correlated with concrete slump. The test can be successfully used for special concrete mixes, including light and heavy weight concrete.
Kelly ball apparatus is mounted. A tin can is added to hold rags for wip-ing the ball clean after each test. The wooden base serves a double duty. Besides carrying the appara t u s , it can be used as a footboard for the person testing the wet concre t e . How to Make the Kelly Ball Test The big advantage of the Kelly ball test is that it can ...
use of the kelly ball for field measurement of concrete consistency. 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 ...
Kelly ball test is a field test that is used in the fresh concrete. This test is not much extensively covered in Indian Standards. Reasons , Procedures are explained here in the simplest way. Hope this is helpful for you, Thank so much, please do continue your support.
The Kelly Ball Apparatus is used to determine the workability of fresh concrete. Consisting of a hemispherical ended cylinder with a guide frame and handle graduated in quarter inches. This field test determines the depth to which the apparatus will sink under its own weight into fresh concrete.
Specification: The apparatus is used to determine the workability of Portland cement & concrete. The Kelly ball test is considered to be simple and much faster than the slump test. Twice the Kelly ball reading approximately equals the slump. It consists of a cylinder with a ball shaped bottom and handle, together weighing 15 kg.

The ASTM test procedure uses a Kelly Ball to measure when the flowable fill has set up enough to place backfill over it. As described in ASTM D 6024, the test involves dropping a steel ball five times on the surface of the hardened material and measuring the diameter of the impression.
CT19-100 KELLY BALL APPARATUS ASTM C 360 Using for measuring workability of concrete by depth of penetration test. Made of solid machined steel ball, rust resistance finish, with 5” x 1/4” graduation threads into ball handle. The weight of handle and ball is 30 …

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.
Apr 21, 2019 · Concrete testing tools in the field: slump cone and empty cylinders Concrete Slump Tests. Concrete slump testing is used to evaluate the flow characteristics of freshly mixed concrete. To conduct a slump test, concrete is placed into an inverted cone in three stages, using a metal rod to tamp down the concrete after every stage.
Concrete Pavement Mixture Design and Analysis (MDA): Development and Evaluation of Vibrating Kelly Ball Test (VKelly Test) for the Workability of Concrete Due to the low workability of slipform concrete mixtures, the science of rheology is not strictly applicable ...
