Red Seal Bricklayer Practice Exam

What are the three main components of mortar?

1. Sand, brick, and water

2. Sand, cement, and water

3. Cement, clay, and lime

4. Water, aggregate, and lime

The correct answer is: Sand, cement, and water

The correct answer, which includes sand, cement, and water, represents the fundamental components that make up mortar. Mortar is a mixture primarily used in construction for binding building materials, such as bricks or stones, together. The sand in the mixture acts as an aggregate that provides bulk, stability, and prevents shrinkage in the mortar. Cement serves as the binding agent, enabling the mixture to harden and adhere to the surfaces of the construction materials. Water is essential as it facilitates the chemical reaction with cement, allowing the mixture to cure and gain strength over time. Understanding the correct components of mortar is crucial for bricklayers, as the quality and proportions of these materials greatly influence the strength, workability, and durability of the mortar used in various masonry applications.
