The materials typically used in a mortar mix include sand, Portland cement, lime, and water. This combination is essential because each component plays a specific role in the properties of the mortar. Sand acts as an aggregate that provides bulk and strength, while Portland cement serves as the primary binding agent that holds the mixture together when it hydrates. Lime is incorporated to enhance the workability and flexibility of the mortar, making it easier to apply. Lastly, water is crucial for the hydration process, allowing the cement to set and bond the materials effectively.

Using this specific mixture ensures that the mortar is suitable for binding materials such as bricks and stones in construction. Other options listed do not represent standard mortar mix components. For instance, asphalt is not used in traditional mortar, brick dust and clay are more associated with other types of masonry or construction elements, and epoxy is not part of a typical mortar mix but rather a strong adhesive used in different applications.
