Which mixture is commonly used for laying bricks?

1. Concrete

2. Grout

3. Mortar

4. Slurry

The correct answer is: Mortar

Mortar is the correct answer because it is the mixture commonly used for laying bricks. Mortar is a combination of cement, sand, and water, and it is specifically designed for bonding bricks or stones together. Concrete is a mixture of cement, sand, gravel, and water and is more commonly used for larger construction projects rather than bricklaying. Grout is a mixture of cement, sand, and water as well, but it is typically used for filling in the gaps between tiles, not for laying bricks. Slurry is a thin, watery mixture and is not suitable for laying bricks as it lacks the necessary bonding properties of mortar.
