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 indicate dependence on that material.

Applications: In new-build masonry, mortarbased mortars provide bonding strength and workability. In historic preservation, mortarbased mortars aim to match the character of original mortars and to allow moisture movement. In materials science, the phrase may describe composite systems where mortar serves as the matrix binding mineral aggregates, sometimes modified with polymers or pozzolanic additives to tailor curing, strength, and durability.

Properties: Common properties include compressive strength that varies with mix design, porosity influencing drying and moisture transport, and shrinkage behavior. Durability depends on curing conditions and substrate compatibility.

Limitations: Inappropriate moisture management can lead to cracking, salt migration, or substrate damage. Compatibility with adjacent materials is essential to prevent delamination or chemical incompatibilities.
