Show details on Drawings of special conditions and shapes if required.
Special Shapes: Include corners, edge corners, and end edge corners.
Thin brick units with higher rates of absorption than values in first subparagraph below should be wetted before placing concrete to improve bond. Before retaining paragraph, verify that thin brick selected complies with requirements.
Initial Rate of Absorption: Less than 30g/30 sq. in. (30g/194 sq. cm.) per minute when tested per ASTM C 67.
Efflorescence: Provide brick that has been tested according to ASTM C 67 and is rated “not effloresced.”
Delete subparagraph below if surface-colored brick is not used.
Surface Coloring: Brick with surface coloring, other than flashed or sand-finished brick, shall withstand 50 cycles of freezing and thawing per ASTM C 67 with no observable difference in the applied finish when viewed from 10 feet (3 m).
