With regard to removing wood forms in hot weather concreting, to retain moisture, it is best to ______.

• A. A. Cover the concrete with wet burlap
• B. B. Lightly sprinkle with cool water
• C. C. Use ice in the place of water
• D. D. Cover the concrete with plastic

Answer: (D)

Covering the concrete with plastic is an effective method for retaining moisture during the curing process, especially in hot weather. The plastic acts as a barrier that prevents moisture from evaporating rapidly due to high temperatures. This helps maintain a consistent hydration environment, which is essential for the chemical reactions that occur during the curing of concrete. Proper moisture retention is crucial to achieving the desired strength and durability of the concrete. Using plastic can also help regulate temperature fluctuations, thus preventing the potential for cracking that can occur when concrete dries too quickly. As the moisture is kept trapped under the plastic covering, it ensures that the curing process is more controlled and efficient. While other methods may provide temporary relief or moisture retention, they often do not provide the same level of effectiveness or longevity in moisture control as using plastic sheeting.
