Which of the following characteristics describes Type V cement?

Type V cement is specifically designed to be sulfate-resistant, which is its distinguishing feature. This characteristic is particularly important in construction environments where the concrete will be exposed to high levels of sulfate, such as in soil or groundwater, which can lead to deterioration of standard concrete. The added resistance to sulfates helps ensure the longevity and durability of structures, especially in areas with aggressive environments.

In contrast, while low heat of hydration, general purpose use, and high early strength are important characteristics of other cement types, they do not apply to Type V cement. For example, Type I cement is typically general purpose and may have a higher heat of hydration, while other types focus on strength development. Thus, understanding the unique properties of Type V cement is crucial for selecting the appropriate cement type for specific structural requirements.
