Test 1 : Standard Slump and Flow Table Tests Objective To determine the reference slump value for Kistner concrete mix design and to calibrate it against an equivalent measure using a flow table.

The mold for the test is in the form of the frustum of a cone having height 30 cm, bottom diameter 20 cm and top diameter 10 cm. Slump test. We all use mostly RMC on site. 1.

The test is popular due to the simplicity of apparatus used and simple procedure. Definition – Slump is the gap between the mold top (after removal) and the top of result concrete. Equipments Required for Concrete Slump Test Mold for slump test i.e. 4.1) is filled with the material to be tested.The mould is then lifted and flow occurs. The slump test is used to measure concrete consistency. The test is carried out in accordance with BS EN 12350-2, Testing fresh concrete. Required Equipment Slump test as per IS: 1199 – 1959 is followed.The apparatus used for doing slump test are Slump cone and Tamping rod. Slump test. 4. From a practical point of view, two geometrical quantities can be measured as the result of the test: the slump (i.e. The time taken by the concrete to take cylindrical shape after the conical shape disappears is noted. Results of Slump Test on Concrete. Concrete Slump Test is a standard and quick test to determine the proportions of various ingredients for preparing concrete of desired consistency and workability. Workability: The ease with which one can work with concrete is called workability this can be measured using a simple test called the slump test.

United Kingdom & Europe.

To maintain the workability and quality of fresh concrete, it is necessary to check batch by batch inspection of the concrete slump. the difference between the initial height of the sample and its final height) or the spread diameter, also called slump flow.


Slump Test Compaction Factor Test Vee-bee Consistometer Test 1. The British Standards do not explicitly specify that the cone should only be … Collect a sample of concrete to perform the slum test.

Objective The word ―workability or workable concrete signifies much wider and deeper meaning than the other terminology ―consistency often used loosely for workability. Flow test 4. The concrete slump test or slump cone test is the most common test for workability of freshly mixed concrete which can be performed either at the working site/field or in the laboratory. Boger a) Department of Chemical Engineering, University of Melbourne Parkville, V ictoria 3052, Australia J. Summers and D. J. Glenister Residue Development Alcoa Australia, Booragoon, W .A. Kelly ball test 5. It is used, indirectly, as a means of checking that the correct amount of water has been added to the mix.

It can also be used as an indicator of an improperly mixed batch.
The consistency, or stiffness, indicates how much water has been used in the mix. Slump for the given sample= _____mm. Different Test Methods for Workability Measurement Depending upon the water cement ratio in the concrete mix, the workability may be determined by the following three methods. Type of Test for determination of workability / consistency of fresh concrete.

Procedure to determine workability of fresh concrete by slump test. Results & Frequency of Test of Slump. s) from measurements of the final slump and the slumping time with the modified slump test for a concrete with a density of 2400 kg/m 3. Since 1922 slump test has been widely used to check out the concrete workability at the site. Then the vibration is started and the time on a stop watch is noted. Shear Slump: Component of the concrete (apex part) slides to one side.

Role of workability Test in "Concrete Design Mix Calculation” 5. 3. Compaction factor test 3. Procedure of Slump Flow Test on Self Compacting Concrete About 6 liter of concrete is needed to perform the test, sampled normally. Background . 5. Concrete is poured into a cone and rodded according to proper procedure. This test is carried out with […] Moisten the base plate and inside of slump cone, place base plate on level stable ground and the slump cone centrally on the base plate and hold down firmly. The concrete slump test is known as "Standard Test Method for Slump of Hydraulic-Cement Concrete" and carries the code (ASTM C 143) or (AASHTO T 119). K-Slump Test.
