How To Do A Concrete Slump Test | Workability Of Concrete

Test 5. Vee-Bee consistometer test. Test 6. K-Slump Test. Concrete Slump Cone Test or Slump Cone Test of Concrete. The prime objective of the concrete slump test or slump cone test is to find out the workability or uniformity of concrete mix produced at the laboratory or the construction site all through the advancement of the work.

Concrete slump test and Factors which influence that

The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. The slump is carried out as per procedures mentioned in ASTM C143 in the United States, IS: 1199 - 1959 in India and EN 12350-2 in Europe .

Slump test of Concrete – we civil engineers

24/01/  · AIM: To determine the workability of fresh concrete by slump test as per IS: 1199 - 1959. APPARATUS: Slump cone Tamping rod PROCEDURE: The internal surface of the mould is thoroughly cleaned and applied with a light coat of oil. The mould is placed on a smooth, horizontal, rigid and

Concrete slump test - Infogalactic: the planetary

The slump test is suitable for slumps of medium to high workability, slump in the range of 5 - 260 mm, the test fails to determine the difference in workability in stiff mixes which have zero slump, or for wet mixes that give a collapse slump. It is limited to concrete formed of aggregates of less than 38 mm (1.5 inch).

A cone penetration test for workability of fibre

An extensive experimental investigation in which various conventional workability tests and the new cone penetration, test are conducted on fresh fibre concrete is described. The effect of fibre content, fibre geometry and water/cement ratio on workability as reflected by slump, ACI inverted cone, V-B time and the new cone penetration test are

Solved] Which one of the following is not a workability

The workability of concrete can be measured using the following methods, 1) Slump test: The slump test is a measure of consistency or the wetness of the concrete mix. It is suitable for field applications, suitable for concrete of high and medium workability. Slumps for various types of concrete is measured in mm. 2) Compacting factor test:

Slump Test Experiment - Apparatus - Types - Procedure

Slump test is a laboratory or site experiment civil engineers perform to assess the workability of the concrete.With such, the test is also referred to as slump cone test or concrete workability slump test. During concrete pouring, you need to check the uniform quality of concrete in terms of consistency and workability. Fresh concrete testing is a very important part and parcel to ensure

Slump test -

Slump test. It is the most common method for measuring the workability of freshly mixed concrete. It can be performed both in lab and at site. Uniformity of the concrete regarding workability and quality aspects can be assessed from batch to batch by observing the nature in which the concrete slumps.

Slump Test of Fresh Concrete with Slump Cone » Civil

If a collapse slump is achieved, a fresh sample should be taken and the test repeated. A collapse slump will generally mean that the mix is too wet or that it is a high workability mix, for which the Flow Table Test is more appropriate. 4. Shear Slump. If one half of the cone slides down, it is called a shear slump.

Determining the Consistency of Concrete | Concrete Technology

The slump test is incapable of differentiating between concretes of very low (zero slumps) workability or two concretes of very high workability (collapse slump). More over the test results may be used as simple statement of qualitative behaviour of concrete under specific conditions.

Slump Test of concrete [5 Step by Step] Procedure

Since 1922 slump test has been widely used to check out the concrete workability at the site. This test is also known as the slump cone test.The slump test measures the consistency or workability of concrete. It is used to check the workability of freshly made concrete for the easy placement of concrete.

Standard Test Method for Slump of Hydraulic-Cement Concrete

1. Scope. 1.1 This test method covers determination of slump of hydraulic-cement concrete, both in the laboratory and in the field. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets.

Concrete Slump Cone Test - PRODYOGI

A measuring scale or ruler. Tamping Rod. Concrete Slump Cone Test Apparatus. The test apparatus consist of a mould in the shape of a frustum of a cone. The base diameter of the cone is 8 inches, diameter is 4 inches and height is 12 inches. In Indian Standard Codes, the slump height is 30cm, top and bottom diameters are 10 and 20 cm respectively.

All About Slump Cone Test - Web Of Concrete

Slump cone test is based on the behavior of frustum or slump cone under the action of gravity. It is an on site test to check the consistency and Workability of concrete to be used.By this test you can quickly see if the concrete is good for your construction purpose or not.

Concrete Slump Test - Experiment Procedure [Civilology

Procedure to do the slump test. The Inner surface of the cone should be free from dust & moisture. Apply one coat of oil inside. Ensure the place is smooth and horizontal where you going to place the cone. First, fill up the cone with concrete 1/4th of the height. Tamp the concrete layer with 20-25 times with help of tamping rod.
