They are used to adjust the alignment of the bricks

Question 2: What is the primary function of ?head joints? in brickwork?

Which action should you take?

Choose only one option

To increase the bonding strength of the bricks

To reduce the width of the wall

Question 5: How does aggregate size influence the workability of concrete for masonry?

Which action should you take?

Choose only one option

Larger aggregates increase workability without affecting strength

Larger aggregates reduce workability but increase the strength of the concrete

Aggregate size does not impact workability or strength

Smaller aggregates improve strength but reduce workability
