Slaking is the process of mixing lime with water and sand to create mortar, which is used for binding bricks and stones.
12. A common material used for waterproofing in construction is:
Answer:
Explanation:
Bitumen, a viscous black mixture of hydrocarbons, is commonly used for waterproofing and roofing due to its water-resistant properties.
13. The ingredient in cement that regulates the setting time is:
Answer:
Explanation:
Gypsum is added to cement to regulate its setting time, preventing it from setting too quickly.
14. The main advantage of using steel in construction is its:
Answer:
Explanation:
Steel is widely used in construction due to its high strength-to-weight ratio, allowing for the construction of large and complex structures.
15. The characteristic of being able to withstand heavy loads without failure is known as:
Answer:
Explanation:
Strength is the capacity of a material to withstand loads without failure, a crucial property for construction materials.
16. Which type of glass is typically used for windows?
Answer:
Explanation:
Float glass is commonly used for windows due to its clarity, uniform thickness, and cost-effectiveness.
17. The primary reason for adding admixtures to concrete is to:
Answer:
Explanation:
Admixtures are added to concrete to modify its properties, such as improving workability, increasing set time, or enhancing durability.
18. The main component of glass is:
Answer:
Explanation:
Glass is primarily made from silica sand, along with other compounds like lime and soda ash, melted at high temperatures.
