This fast drying formulation allows crews to complete work more quickly and produces cleaner of subsequent concrete pours. In some countries wax, petroleum-based substances or grease are used as bond breakers, but these chemicals will change characteristics of the surfaces on which they are applied. See Clay and Concrete Masonry Banding Details, TEK 5-2A (ref. Reinforcing Bar Positioners: Wire units designed to fit into mortar bed joints spanning masonry unit cell with loops for holding reinforcing bars in 2.12 PREFORMED CONTROL JOINT They can also be divided into water-based or non-water based products. Environmentally Friendly: Material is CFC and HCFC-free. Small dabs of bituminous cement may be used to hold felt sheets in place during subsequent placing operations. 0000008120 00000 n An engineered method is presented in TEK 10-3 Control Joints for Concrete Masonry WallsAlternative EngineeredMethod, which is based on limiting crack width to 0.02 in.

When used as a shear key to transfer out-of-plane loads between two panels separated by a control joint, the gasket material should be tested to determine its strength and applicability in this application. Stake for Screed Key and Load Key PACKAGING WebA geotextile bond breaker is a nonwoven, needle punched fabric used between new concrete and an existing cementitious pavement layer. (305 mm) past the vertical reinforcement adjacent to the opening (Figure 2c), joint reinforcement maybe placed in the first two mortar joints above the opening and extended to the control joint on each side, or a horizontal bond beam could be used, as shown in Figure 2d. Threaded Bar 1) Bond breaker applied through placed reinforcement will have irregularities in thickness and surface that will cause shadowing of reinforcement patterns onto exposed surfaces. Figure 3h is a variation on this approach, where one horizontal bond beam reinforcing bar extends across the control joint, and is similarly debonded to allow longitudinal movement. Easy-Lift FD is applied to the concrete casting slab to efficiently prevent the bonding During hot weather concreting as defined in ACI 305 Guide to Hot Weather Concreting, the use of 1100, VOCOMP Series or wet curing is recommended in conjunction with TILT-CRETE. TILT-CRETE 8). If you have any questions or would like to learn more, please contact us. %PDF-1.4 % Bond breakers are available in different forms, such as liquid, spray, rods, and tape. While these attributes are the primary basis for concrete masonrys popularity, performance should not be taken for granted. WebGuide to Tilt-Up Bond Breakers A bond breaker is a material used to prevent adhesion of the newly placed concrete to the substrate. MASTERSEAL NP1 CAULKIING SEALANT WHITE 10 OZ TUBE (50426722). }|aY/?.dId\NfsN=!

Both would actually be better. Joint reinforcement and other horizontal reinforcement should be discontinued at control joints unless it is required for structural purposes, as it will act to restrain horizontal movement. Sure Plug - Insertion Tool 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. WebWater-Based Concrete Bond Breaker.

Proper application of crack control measures, including control joints when required, can help ensure satisfactory performance of the concrete masonry. When a bond breaker is needed at a construction joint, a curing compound, form release agent and the like can act as a bond breaker. Provides effective bond breaker between casting slab and tilt-up or lift-slab panel.

WebBond breakers and their effective use Guidelines to prevent stuck panels and aggravation Lift-slab construction, a method in which concrete floor and roof slabs are cast in a stack The polyurethane material does not adhere to sealants, so proper 2-sided joints are created and the joint meets sealant joint specifications requireing a bond breaker. Welding Coil Tie As previously mentioned, another method of providing out-of-plane load transfer between the panels on either side of a control joint is to place a smooth dowel across the control joint as shown in Figures 3f and 3i. Where external loads are an issue in combination with internal volume change, the design should consider the combined effects of these influences on cracking. Table 1 indicates a maximum control joint spacing of the lesser of: In this example, the maximum spacing of 25 ft (7.62 m) governs over the length to height ratio. Stake Driving Tool In walls containing vertical reinforcement, the cell adjacent to the opening is usually grouted and reinforced to provide solid support and additional strength for jambs. Sure Lock Strongback Clamp 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. To resist the lateral movement around the slip plane, 24-in. Price/Bag. Strap Tie When control joints are required, concrete masonry only requires vertical control joints. Non-membrane bond breakers are subdivided into reactive and non-reactive. 0000007430 00000 n See Table 2B for horizontal reinforcement spacing translating to 0.034 in./ft (72.0 mm/m) of height.
