Which of the following is true about curing concrete?

Curing is an essential process in concrete finishing that significantly affects the final strength and durability of the concrete. It involves maintaining adequate moisture, temperature, and time to allow the concrete to achieve its required strength. During the curing process, proper hydration is crucial, as it allows the cement particles to react with water and develop strength over time. Skipping or inadequately performing the curing can lead to weak concrete that is more susceptible to cracking, surface defects, and reduced longevity.

The other choices reflect misconceptions about the curing process. While curing is more challenging in hot weather due to increased evaporation, it is not limited to these conditions and is critical in all weather to prevent the concrete from drying out too quickly. Additionally, using water does not replace the need for proper curing techniques, which are designed to provide consistent moisture and environmental stability. Moreover, concrete always benefits from curing, as it is integral to ensuring the material sets correctly and achieves its full potential for strength and durability over time.
