Workability: Definition: Concrete Slump Test is a standard and quick test to determine the proportions of various ingredients for preparing concrete of desired consistency and workability. scope: This test method covers determination of slump of hydraulic-cement concrete, both in the laboratory and in the field. EN 12350-2 in Europe. Slump cone [ 100 mm (4 in) upper dia, 200 mm (8 in) lower dia and 300 mm (12 in) height ] Tamping rod [ 600 mm (24 in) high, 15 mm (5/8 in) dia and hemispherical tip at both ends ] Concrete Slump Test is a measurement of concrete's workability, or fluidity. The water content was adjusted to compensate for the dry gravel and sand used in the lab. Concrete is placed into a cylindrical steel mold with an inner diameter of 36 mm. The slump test is very simple and easy to handle. “Concrete slump test - Wikipedia” “The concrete slump test measures the consistency of fresh concrete before it sets. The slump test is the most simple workability test for concrete, involves low cost and provides immediate results.

UTC-0406A  Slump Cone Funnel, made of seemless spun steel, should be ordered separately. ASTM C143/C143M - Standard Test Method for Slump of Hydraulic-Cement Concrete Published by ASTM on December 15, 2015 This test method covers determination of slump of hydraulic-cement concrete, both in the laboratory and in the field. The values stated in either SI units or inch-pound units are to be regarded separately as standard. Note 1: This test method was originally developed to provide a technique to monitor the consistency of unhardened concrete. The test is popular due to the simplicity of the apparatus used and simple procedure. Under laboratory conditions, with strict control of all concrete materials, the slump is generally found to increase proportionally with the water content of a given concrete mixture, and thus to be inversely related to concrete strength. It is performed to check the work-ability of freshly made concrete, and therefore the ease with which concrete flows. C172 (T/F) The slump mold should be in a dry condition before beginning the test. The consistency, or stiffness, indicates how much water has been used in the mix. Concrete Slump Test International Standard. This test plays a vital role in ensuring immediate concrete quality in a construction project. The sample of concrete for use in making the slump test must be obtained in accordance with ASTM Standard _____. 1- American Society for Testing and Materials (ASTM): ASTM slump test standards are ASTM C 143, ASTM C143M. Standards ASTM C143; AASHTO T119 The Slump test method is used for the determination of the consistency and workability of fresh concrete. It can help give an idea of workability, telling you how easy or hard it will be to place, and can help to predict strength. If you should ever need to sample from a paving mixer, open-top truck mixer, or other type of equipment, be sure to refer to the most recent ASTM C 172. Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction. ASTM C143 in the United States, IS: 1199 – 1959 in India, and . Significance and Use of ASTM C143 Slump is a measure of the consistency of a sample of concrete, and tells you how fluid the concrete will be. Due to this fact, it has been widely used for workability tests since 1922. The flow table test procedure does not conform with ASTM standard and is as follows.

5.1  This test method provides a procedure to determine the slump flow of self-consolidating concrete in the laboratory or the field.

The concrete slump test is an on-the-spot test to determine the consistency as well as workability of fresh concrete.
