Volumetric concrete provides the precise mix you need for your project. Most concrete mixes use cement combined with water and an aggregate which is usually made up of sand and stone. 
 
Some concrete includes additional materials to meet specialist requirements. Fibres can add strength while plasticisers improve flow and workability. Additives can speed up or slow down setting and reduce corrosion where steel rebars are used.

Until recently, the fluidity of concrete has always been referred to as the concretes Slump, its now referred to as the concretes Consistence. We will refer to the fluidity of concrete as slump. 

Understanding Concrete Slump and Its Importance in Construction 

When it comes to concrete, selecting the right type for your project is crucial for achieving optimal results. One essential factor to consider is the concrete's "slump," which refers to its consistency before it sets. So, what is concrete slump and why does it matter. 
 

CONCRETE SLUMP WHAT IS IT? 

CONCRETE SLUMP WHAT IS IT? 

Concrete slump is a measurement of the flowability of fresh concrete. The higher the slump, the more fluid the concrete is. This term may sound complex, but it's simply measured by testing how much a pile of concrete slumps down when left to stand. To do this, a slump cone is filled with a sample of the concrete, following a specific procedure, the cone is removed, and the distance from the top of the cone to the top of the concrete slump is measured.

In general, S1 concrete is ideal for kerb and pipework bedding, S2 for strip footings and hard-standing slabs, and S3 for trench-filled foundations that require high flowability. S4 and S5 concretes are typically used for specialist applications such as foundations, slabs, and pumping/piling concrete and require the assistance of an experienced concrete technologist.

Concrete slump is classified according to its average slump value, ranging from S1 to S5. The table below shows the different classes, their slump ranges, and target slumps. The S1 class is a relatively dry mix, while S5 has the highest fluidity. 
 
It is important to remember that just adding additional water to the concrete will alter the Water/Cement (W/C) ratio and too much water means you may not achieve the required strength and increase the risk of shrinkage and cracking. Its always advisable to increase the cement content or use a water reducing admixture to maintain the W/C ratio without impacting the strength. 
 

IMPORTANCE OF A SLUMP TEST MAKING THE RIGHT CHOICE 

IMPORTANCE OF A SLUMP TEST MAKING THE RIGHT CHOICE 

Performing a slump test is essential to determine the workability and flowability of different concretes. It helps to ensure that the concrete is mixed correctly, avoiding improper batch mixes. By conducting a slump test, you can choose the right concrete for the job, ensuring that your project meets the desired specifications and quality standards. 
 
Understanding concrete slump is vital for selecting the right type of concrete for your project. By determining the appropriate slump class and performing a slump test, you can ensure that your concrete is correctly mixed, flows efficiently, and meets your project's desired specifications.
