The slump value for pumpable concrete varies depending on the mix design and application.

• Slump value is the measure of the consistency of concrete.

• Pumpable concrete typically has a higher slump value than traditional concrete.

• The slump value for pumpable concrete can range from 150mm to 200mm.

• The mix design and application will determine the appropriate slump value for pumpable concrete.

Slump is measured by placing a slump cone on a flat surface and filling it with concrete. The cone is then lifted and the slump is measured.

• Place a slump cone on a flat surface

• Fill the cone with concrete in three layers

• Compact each layer with a steel rod

• Remove the excess concrete from the top of the cone

• Lift the cone vertically and measure the slump

• Repeat the process for consistency
