Concrete Slump Test Concrete Exchange

A concrete slump test is used to determine the correct water content in a batch of concrete. “Slump” is the distance, measured in inches, the concrete settles after the slump cone is removed. A concrete batch with high slump is an indication that the concrete has to much water in it and will likely be weak when fully cured.

Estimating Concrete Workability Based on Slump Test with ...

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. This research proposes a machine learning model for predicting ...
