With masonry units, bonding is achieved by using _________.
- A.
Cement
- B.
Mortar
- C.
Grout
- D.
Mortar and grout
Correct Answer
D. Mortar and groutExplanation
Masonry units, such as bricks or concrete blocks, require bonding to ensure structural stability. Bonding is achieved by using mortar and grout. Mortar is a mixture of cement, sand, and water that is used to bind the masonry units together. It provides a strong adhesive bond between the units. Grout, on the other hand, is a mixture of cement, sand, and water that is used to fill the gaps between the masonry units. It helps to further strengthen the structure and improve its appearance. Therefore, both mortar and grout are essential for achieving proper bonding in masonry construction.Rate this question:
