The shape of slump in a slump cone test is typically conical.

• The shape of slump is conical, with the top being wider than the base.

• The height of the slump is measured to determine the workability of the concrete.

• Different types of slumps (true slump, shear slump, collapse slump) indicate different levels of workability.

• Example: A true slump has a smooth, symmetrical shape with a slight collapse at the center.

Lapping zone of column is where two reinforcement bars overlap to ensure continuity of load transfer.

• Lapping zone should be at least 50 times the diameter of the smaller bar away from the face of the support.

• Proper lapping length is crucial for structural integrity and load distribution.

• Lapping should be staggered in multiple layers for better strength.

• Ensure proper cover and clear spacing around the lapping zone to pr
