Mortarbased
Mortarbased is an adjective used to describe materials, systems, or processes that rely on mortar as the primary binding or structural component. In construction and masonry, mortarbased formulations use cementitious mortars—typically lime, cement, or combinations—to bind aggregates such as sand or crushed stone into bricks or blocks. In restoration, mortarbased approaches emphasize compatibility with historic substrates, often selecting hydraulic lime or lime-putty mortars to maintain vapor permeability and reversibility.
Etymology: The term derives from mortar, the binding paste used in masonry, with the suffix -based to
Applications: In new-build masonry, mortarbased mortars provide bonding strength and workability. In historic preservation, mortarbased mortars
Properties: Common properties include compressive strength that varies with mix design, porosity influencing drying and moisture
Limitations: Inappropriate moisture management can lead to cracking, salt migration, or substrate damage. Compatibility with adjacent
