Question

How is the reaction of quicklime and water commonly used in the construction industry?

a) To produce heat for buildings
b) To make bricks
c) To produce concrete
d) To make mortar and plaster

Answer 1

The reaction of quicklime and water is commonly used in the construction industry to make mortar and plaster.

Step-by-step explanation:

The reaction of quicklime (CaO) and water is commonly used in the construction industry to make mortar and plaster. When quicklime reacts with water, it produces slaked lime (Ca(OH)2) as the result. This reaction is highly exothermic, meaning it releases a significant amount of heat. The heat produced during this reaction is utilized in the construction industry to speed up the drying and hardening process of mortar and plaster. Therefore, the correct answer is option d) To make mortar and plaster.
