Preview Questions Mason/Bricklayer | Role Specific Skill

Question 1: How does the use of a higher-than-recommended water-to-cement ratio affect the concrete's long-term durability?

Which action should you take?

Choose only one option

Enhances the concrete's resistance to chemical reactions in the soil

Increases permeability, reducing resistance to freeze-thaw cycles

Decreases concrete's workability and ease of placement

Increases tensile strength while decreasing compressive strength

Question 2: What is the effect of using too much sand in a mortar mix for bricklaying?

Which action should you take?

Choose only one option

Weakens the bond strength of the mortar

Improves the workability of the mortar

Decreases the water retention in the mix

Increases the curing time

Question 3: What is the role of a screed in floor preparation for tile installation?

Which action should you take?

Choose only one option

To strengthen the tiles by making the floor uneven

To reduce the amount of mortar needed for installation

To create a level, stable, and smooth surface that ensures proper adhesion of tiles

To add color and texture to the floor surface before tiling

Question 4: How should a mason maintain alignment when laying bricks over large areas?

Which action should you take?

Choose only one option

By using a string line and corner blocks to maintain straight courses

By relying on visual cues and adjusting bricks as needed

By adjusting mortar thickness instead of brick placement

By using a single point of reference for alignment

Question 5: How can a mason ensure uniform consistency and strength in a concrete mix during manual mixing?

Which action should you take?

Choose only one option

By adding extra aggregates for bulk

By using a larger trowel for better mixing

By mixing for a consistent amount of time and adding water gradually

By mixing with only coarse aggregates

Question 6: What is the primary advantage of using clay bricks in construction?

Which action should you take?

Choose only one option

Resistance to moisture

Good insulation properties

High compressive strength

Low cost and easy availability
