  • What Is Meant By ‘Concrete Slump’ & Why Does It

    2019-10-10 · Why do a slump test? A concrete slump test is a way of finding out the consistency of different concretes. The benefits of performing a slump test are that it shows the workability of the concrete and the ease with which it flows, as well as being an indicator of an improperly mixed batch.

  • Concrete Slump Test Definition, Procedure And Types

    The slump test is a standardized procedure performed on fresh, wet concrete to determine its consistency and ability to flow. The test consists of filling a conical mold with concrete to a specified height. The mold is then removed, and the concrete is allowed to deform under its own weight.

    2007-7-1 · In this paper, the slump flow is a function of the content of all concrete ingredients, including cement, fly ash, blast furnace slag, water, superplasticizer, coarse aggregate, and fine aggregate. We will compare ANN and second-order regressions in modeling concrete slump flow, and explore these models with response trace plots to observe the slump flow behavior.

    Concrete workability, quantified by concrete slump, is an important property of a concrete mixture. Concrete slump is generally known to affect the consistency, flowability, pumpability, compactibility, and harshness of a concrete mix. Hence, an accurate prediction of this property is a practical need of construction engineers.

  • Estimating Concrete Workability Based on Slump Test

    2018-8-9 · Since SLUMP and FLOW both describe the consistency (rheologic properties) of fresh concrete, it is reasonable that they correlate somehow. Mechtcherine and Shyshko (2015) prodive a mathematical description of this process using a discrete element approach . Moreover, we can assume that both are not correlated with compressive strength since that is the result of other processes during hardening (aging) of the concrete.
