concrete felt bond breaker

Care should be taken when constructing this type of control joint to ensure that excessive mortar is not placed in the head joint of the two control joint units, whichcan potentially lead to bonding of the two panels. It's purpose is to control the amount of caulking that goes into the joint, but more importantly, to "break" the 3 point "bonding" that occurs in the back of the joint and thus prevents the caulking from tearing open at this location. After concrete cures, clean joint area, and fill with sealant, to a height below the top surfaces. 0000011201 00000 n Swift Lift Anchors Reinforcing Bar Positioners: Wire units designed to fit into mortar bed joints spanning masonry unit cell with loops for holding reinforcing bars in In Figure 2a, continuous vertical reinforcement cannot be provided in the cell adjacent to the opening on the left, as crossing the horizontal portion of the control joint (i.e., the slip plane) would effectively pin the two sections together, restraining relative movement. 0000040018 00000 n Standard Classification System for Rubber Products in Automotive Applications, ASTM D2000-18.
