Cemented

Cemented is an adjective meaning bonded, fixed, or joined by cement, or a verb form indicating that cement has been used to join materials. In construction and materials science, cement is a binding agent; products described as cemented have surfaces bonded by a cementitious material such as Portland cement, lime-based mortar, or epoxy. Examples include cemented masonry joints, cemented tiles, and cemented concrete structures. The strength and durability depend on the cement type, aggregate, mixing ratio, curing, and environmental conditions.

In geology, cementation is a diagenetic process whereby minerals precipitate from pore waters and bind sediment grains together, strengthening sedimentary rocks. Common cements include calcite, silica (quartz), and iron oxide cements. Rocks that are cemented include sandstone and clays that have undergone diagenetic cementation.

In medicine and dentistry, cemented refers to using an adhesive material to fix implants or prosthetics to bone or tooth structure. In orthopedics, cemented arthroplasty uses bone cement, typically polymethyl methacrylate, to anchor implants. In dentistry, cemented crowns or inlays are attached with dental cement, a resin- or glass-ionomer-based material.

Cemented contrasts with mechanical fixation, where components rely on mechanical interlock rather than adhesive bonding. The term is used across disciplines to denote a bonded, set, or fixed condition produced by cementitious materials.
