Slump Test – For Workability of Concrete

During concrete construction projects, it is essential to conduct material testing to ensure quality and consistency. Construction projects are known for their inherent risks, leaving no room for errors in fact, tests like slump testing and other feasibility assessments come into play to prevent failures in construction projects. They help ensure that project standards are met, reducing the risk of problems before the project is completed.

Concrete Slump Test is the common method to measure the workability of concrete, in the previous post we understood it in detail if you missed it then do check out the informative post to know about “Workability of Concrete”; Furthermore, we have already explained in detail the number of factors affecting the workability of concrete such as the water cement ratio, and the gradation of aggregates and mixes used and the procedures for using and placing them.

Understanding the Slump Test in Concrete Quality Control
The slump test is done by filling a truncated cone shaped mould with freshly mixed concrete and then removing the mould. Slope is measured as the height difference between the top of the mould and the top of the concrete after removing the mould.

This method can be employed either in a laboratory or at a work site. However, it is not suitable for very wet or very dry concrete mixtures as it may not accurately measure all contributing factors to workability.

Place the mould on a smooth, horizontal, and non-absorbent surface.
Fill the mould in four layers, with each layer approximately 1/4th of the mould’s height.
Tamper each layer 25 times using the tamping rod, ensuring even distribution of strokes across the cross-section.
