Which of the following is a common trait of gypsum used in building?

Gypsum is known for its ability to withstand high temperatures, which makes it a vital material in the construction industry, especially in fire-resistance applications. When exposed to high heat, gypsum does not catch fire easily; instead, it can lose water content and form a protective layer that helps slow down the spread of fire. This quality is key in many fire-rated assemblies, such as gypsum wallboard, which are designed to improve fire safety in buildings. Therefore, its capacity to degrade under high heat without being highly flammable allows for better management of fire hazards within structures.

The other options highlight characteristics that gypsum does not possess. For instance, while it can be affected by heat, it does not degrade in a manner that compromises the structural integrity immediately. It is not used as a primary structural material like steel or concrete, nor is it primarily used for aesthetic purposes, although it can have decorative finishes. Its primary function in construction leans more toward providing fire resistance and sound insulation rather than serving as a structural or aesthetic component.
