4.1 This test method is intended to provide the user with a procedure to determine slump of plastic hydraulic-cement concretes. Note 1—This test method was originally developed to provide a technique to monitor the consistency of unhardened concrete. 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. Under field conditions, however, such a strength relationship is not clearly and consistently shown. Care should therefore be taken in relating slump results obtained under field conditions to strength.

4.2 This test method is considered applicable to plastic concrete having coarse aggregate up to 11/2 in. [37.5 mm] in size. If the coarse aggregate is larger than 11/2 in. [37.5 mm] in size, the test method is applicable when it is performed on the fraction of concrete passing a 11/2-in. [37.5-mm] sieve, with the larger aggregate being removed in accordance with the section titled “Additional Procedure for Large Maximum Size Aggregate Concrete” in Practice C172.

4.3 This test method is not considered applicable to non-plastic and non-cohesive concrete. Note 2—Concretes having slumps less than 1/2 in. [15 mm] may not be adequately plastic and concretes having slumps greater than about 9 in. [230 mm] may not be adequately cohesive for this test to have significance. Caution should be exercised in interpreting such results.
