Put tear off strip facing down if no caulking is planned. Sure Lock Tie Stake for Dowel Baskets It is placed to ensure that there is no adhesive molecular bond between the surfaces. For example, locating control joints at the ends of lintels may compromise arching action. Another alternative is to place the control joint away from the opening if adequate tensile reinforcement is placed above, below and beside the opening as discussed below. Where the keying action is provided by concrete materials, a four-hour fire rating is provided. 0000053409 00000 n German engineers have been Price/Tube. Foundation walls traditionally do not include control joints due to concerns with waterproofing the joint to withstand hydrostatic pressure.

Tower Chair Waler Tie 5 Gallon (18.93 L) Pails Steel Ply Because the lintel is not laterally supported at the bottom due to the slip plane, control joints capable of providing load transfer between panels are required, such as the joints shown in Figures 3a, 3d, 3e, 3f, 3h and 3i. They are essentially vertical planes of weakness built into the wall to reduce restraint and permit longitudinal movement due to anticipated shrinkage, and are located where stress concentrations may occur. 0000053803 00000 n Plastic sheet, felt paper, a layer of sand or a chemical bond breaker can be used to prevent bond to the base slab. After concrete cures, clean joint area, and fill with sealant, to a height below the top surfaces. Concrete mix designs that contain in excess of 20% pozzolans such as fly ash may require additional coats of the bond breaker. Apply the second coat of TILT-CRETE at right angles to the previous coat. Potential cracking resulting from externally applied design loads due to wind, soil pressure, seismic forces, or differential settlement of foundations is controlled by structural design considerations not addressed here. Approval may be granted for the application of 1100 concrete cure or one of the VOCOMP series cure-and-seal products from W. R. MEADOWS to be used as a cure coat prior to the application of TILT-CRETE as a bond-breaker. Can use cut 'sonotube ring' or better, polyurethane wrap, to provide a gap for installation, and remove it the first time it is lifted. Reminder: it is very important that nonstructural reinforcement, such as horizontal joint reinforcement which is typically used for crack control only, should not be continuous through a control joint, since this will restrict horizontal movement. Control joints constructed with special unit shapes, as shown in Figure 3e, can also be used to provide a fire-rated control joint and out-of-plane load transfer. If a curing or curing-and-sealing compound other than 1100 or VOCOMP series products are used, they must be removed prior to the application of TILT-CRETE. TILT-CRETE is not recommended to be used with any other manufacturers bond-breakers. 0000008377 00000 n Wood Chamfer 0000029686 00000 n the bonding of subsequent concrete pours.

Notice that the joint goes around the lintel and allowance for movement (a slip plane in the form of flashing or other bond breaker) between the lintel and the masonry must be provided. Although the detail shownin Figure 4a is considered the typical construction, research suggests that the joint profile shown in Figure 4b may offer improved performance because the flat profile reduces peeling stresses at the corners of the sealant.

However, due to congestion in the cell at this location, vertical reinforcement is sometimes placed in the second cell from the opening. Density Range: 2 (lb/ft3), ASTM D3575-00 (nominal). Bond breakers are Thanks. ft./gal Not compatible with hot pour sealants or some chemical sure sealants. In this case, the cell next to the opening should be grouted, as should the cell containing the reinforcement, to provide additional resistance for attaching the door or windowframes. Bond breakers will offer you some additional advantage such as: If you are planning to buy a bond breaker, have in mind the following factors before making a decision: Bond breakers are classified into two major groups: membrane-forming and non-membrane forming. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
