Answer:

Mortar holding weathered bricks

Cement mortar becomes hard when it cures, resulting in a rigid aggregate structure; however, the mortar functions as a weaker component than the building blocks and serves as the sacrificial element in the masonry, because mortar is easier and less expensive to repair than the building blocks. Bricklayers typically make mortars using a mixture of sand, a binder, and water. The most common binder since the early 20th century is Portland cement, but the ancient binder lime mortar is still used in some specialty new construction. Lime, lime mortar and gypsum in the form of plaster of Paris are used particularly in the repair and repointing of historic buildings and structures so that the repair materials will be similar in performance and appearance to the original materials. Several types of cement mortars and additives exist.
