Stone bricks. Small stone ashlars that are cut by the quarry to brick sizing to allow their use in standardized brick-laying workflows. Cost is similar to clay composite bricks, but with greatly reduced carbon emissions. [16] [17] As stone does not change size like fired clay bricks, brick-sized stone ashlars do not require expansion joints.
