slump test practices. If the slump test is to determine whether or not the concrete is to be accepted, the sample must be taken from the early part of the load. Never take the sample from the first concrete out of the mixer. Let out at least 0.2 of a cubic metre before taking a test sample. Concrete slump test - Wikipedia The slump test is used to ensure uniformity for different loads of concrete under field conditions. A separate test, known as the flow table, or slump-flow, test, is used for concrete that is too fluid (non-workable) to be measured using the standard slump test, because the concrete will not retain its shape when the cone is removed. ASTM C143 / C143M - 15a Standard Test Method for Slump of ... 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. SLUMP TEST PROCEDURE (FIELD TESTING) the slump cone. Measure the amount of slump in inches from the bottom of the straight edge to the top of the slumped concrete at a point over the original center of the base. The slump operation shall be completed in a maximum elapsed time of 2 1/2 minutes. Discard concrete. DO NOT use in any other tests. SLUMP TEST PROCEDURE (FIELD TESTING) 1
