Concrete workability can be determined by conducting a slump test.

• Conduct a slump test to measure the consistency of the concrete mix.

• Adjust the water content or use admixtures to achieve the desired workability.

• Consider factors such as temperature, humidity, and type of aggregates in determining workability.

• Consult with concrete mix design experts for guidance on achieving the desired workability.

• Use tools like flow t...read more

Slump test is a method to measure the consistency of concrete before it sets.

• Slump test involves filling a cone-shaped mold with concrete, then lifting the mold to see how much the concrete slumps or settles.

• The amount of slump indicates the workability of the concrete - higher slump means more workable concrete.

• The test helps ensure the concrete is of the right consistency for proper placement and compaction.

• Slump tes...read more

Concrete mix design is the process of selecting suitable ingredients and determining their proportions to produce concrete with desired properties.
