Name one cause of low slump.

What is the primary measure of a slump test?
Think about what workability means in concrete.
True or False: Low slump indicates better workability.
Consider the flow of the concrete.
A construction site receives a batch of concrete with a measured slump of 20 mm when a slump of 75-100 mm is expected. Discuss the potential consequences on workability and structural integrity.
Consider how proper compaction affects strength.
Given that excessive fines lead to low slump, propose a strategy to ensure proper grading of aggregates in mix design.
Refer to aggregate grading tables in the IS codes for guidance.
