Red Seal Bricklayer Practice Exam

Question: 1 / 400

What condition is essential for mortar to cure properly?

Low humidity and high heat

Consistent moisture and appropriate temperature

For mortar to cure properly, consistent moisture and appropriate temperature are crucial. Mortar relies on a process known as hydration, where water is essential for the chemical reactions that enable it to gain strength and durability.

Maintaining consistent moisture helps prevent the mortar from drying out too quickly. Rapid drying can lead to cracking and incomplete curing, which weakens the overall structure. Moreover, the temperature also plays a significant role; extreme cold can slow down the curing process, while high temperatures may cause evaporation to occur too quickly.

By ensuring that the mortar remains consistently moist and is within the optimal temperature range during the curing process, it will develop the necessary strength and performance characteristics required for bricklaying applications.
