Slump Test Equipment

The concrete slump test is a very simple procedure to measure the workability of fresh concrete. Because it involves low-cost tools and can be quickly done in situ, it is used extensively on most construction sites. By measuring the consistency of fresh concrete before it sets, this test can indicate improperly mixed solutions. more »

The concrete slump value determined in this test is used to find the water-cement ratio in mixes. By measuring the difference between the mold height and the height of the specimen, researchers are able to evaluate the concrete consistency. The test is carried out from batch to batch to ensure uniformity of different loads.

In most cases, the test is conducted according to the ASTM C143 specification. The test equipment required includes a standard slump cone, a slump base plate and a graduated tamping rod used to both tamp the concrete mixture and measure the amount of slump. In addition, accessories such as material scoops, funnels, brushes and trowels are often used.

Humboldt provides a complete collection of slump cone testing equipment including test sets, individual components and the K Slump Tester to implement accurate and simple slump testing for the construction industry.
