Red Seal Bricklayer Practice Exam

What is the main characteristic of engineering bricks?

1. High aesthetic value

2. Low compressive strength

3. High durability and strength

4. Standard size and shape

The correct answer is: High durability and strength

Engineering bricks are specifically designed for high-performance applications, which is what makes high durability and strength their main characteristic. These bricks are often made from denser materials and are fired at higher temperatures than standard bricks, resulting in a product that can withstand significant loads and harsh conditions. This makes them suitable for structural and engineering applications, including damp environments, as they also have low water absorption rates. Their composition and manufacturing process ensure that they maintain their integrity under stress and thus are a preferred choice for constructions that demand superior strength and durability. This property sets engineering bricks apart from other types, which may prioritize aesthetics or standardization in size over structural performance. The notable strength of engineering bricks is often why they are used in heavy load-bearing walls, archways, and other critical structural elements.
