Red Seal Bricklayer Practice Exam

The absorption rate of bricks is crucial primarily because it affects the dry-out time of mortar. When bricks have a high absorption rate, they can draw moisture from the mortar more quickly. This can lead to the mortar curing too rapidly, potentially compromising its strength and adhesion. It is essential for a bricklayer to understand this characteristic to ensure proper bonding between the bricks and the mortar, ultimately affecting the integrity and durability of the masonry work.

Moreover, knowing the absorption rate helps in planning for adequate curing times and in selecting the appropriate type of mortar to use in order to accommodate the specific properties of the bricks being utilized. This consideration is key to achieving a solid and long-lasting structure.
