Testing for concrete slump is a quick procedure that can be performed on the jobsite using relatively inexpensive, but specialized, equipment. For ready-mix concrete, the procedures for measuring slump are defined by ASTM C143 – Standard Test Method for Slump of Hydraulic-Cement Concrete.
Concrete slump is one of a suite of fresh concrete tests that include air content, unit weight, temperature, and the molding of laboratory samples for strength tests as specified in ASTM C94. These tests document the properties of the concrete as it is delivered to the job site.
Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction. The slump test is the most simple workability test for concrete, involves low cost and provides immediate results.
Mar 13, 2019 · Slump tests can be done on-site to check the concrete mix has expected fluid properties. In addition, this test can be used to measures consistency between the individual batches. It is a simple and low-cost test prepared at the laboratory or the site during work.
Sep 20, 2023 · The concrete slump test provides valuable information on the workability of concrete. In simple terms, it measures the consistency of concrete before it sets. A slump cone test is performed using a metal mould shaped like the frustum of a cone.
A concrete slump test is a straightforward and essential procedure in the construction industry designed to evaluate the consistency and workability of fresh concrete. This test provides critical insights into the concrete’s fluidity, which directly impacts its strength and durability once it hardens.
