Mortar

Definition

Mortar is a mixture of sand, water, and a binding agent, typically cement or lime, used to hold together bricks, stones, or other masonry units. It plays a crucial role in the construction process by providing structural stability, weather resistance, and aesthetic appeal to buildings. In the context of architectural achievements like Brunelleschi's dome, the quality and composition of mortar directly influenced the overall strength and longevity of the structure.
