Question

What is true about moisture in concrete?

1) It is important to prevent moisture from leaving the concrete
2) It is important to not prevent moisture from leaving the concrete
3) Excessive moisture loss will result in concrete cracking
4) Both 1 and 3

Answer 1

Controlling moisture is essential for concrete's durability. Preventing too much moisture from escaping is just as important as avoiding excessive moisture, as rapid drying can cause cracking. Option 4, both 1 and 3, is correct.

Step-by-step explanation:

When discussing moisture in concrete, it's critical to understand that controlling the moisture content is essential for the material's strength and durability. While excessive moisture should be avoided during the curing process, it is also important to prevent too much moisture from escaping. If the concrete loses moisture too quickly, it is likely to crack due to the drying process. Therefore, it is a balance of maintaining enough moisture to allow the concrete to cure properly without letting it dry too quickly.

To put it simply, the correct options in regards to moisture in concrete are: It is important to prevent moisture from leaving the concrete, and excessive moisture loss will result in concrete cracking. Hence, option 4, which states both 1 and 3, is the correct answer.
