A raked joint is a type of what?

A raked joint refers specifically to a type of mortar joint used in masonry work. In this context, a raked joint is characterized by its recessed appearance, where the mortar is removed or "raked" out of the joint between masonry units, typically bricks. This technique not only contributes to the aesthetics of the wall but also can enhance the bonding strength of the mortar.

Raked joints can improve the visual appeal by creating depth and shadow lines in the masonry surface, which can be particularly desirable in certain architectural styles. Additionally, by allowing more surface area for the bonding agent, they help ensure a stronger connection between the bricks or stones.

The other options pertain to different structural elements: roof joints involve connections in roofing systems, framework joints relate to the connections within a framework or structure, and masonry joints are a broader category that includes various types of joint configurations, but do not specifically define the unique characteristics of a raked joint. Thus, referring to a raked joint as a mortar joint accurately encapsulates its function and design in masonry construction.
