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. USES Then finish concrete joint edges. Reinforcing Bar Positioners: Wire units designed to fit into mortar bed joints spanning masonry unit cell with loops for holding reinforcing bars in Use asphalt felt (No. Always verify the presence of a uniform bond-breaker coat as indicated by a dry, soap-like feel prior to placing panel concrete. Movement joints such as control joints are one method used to relieve horizontal tensile stresses due to shrinkage of the concrete masonry units, mortar, and when used, grout. At other points of wall stress concentration, control joints are used to effectively divide a wall into a series of isolated panels. endstream endobj startxref Prior to any full-scale application of a subsequent paint, coating, sealer, adhesives sealant, grout, etc., W. R. MEADOWS recommends appropriate field testing be performed to verify that all desired/required appearance, performance, adhesion, etc. 0000014833 00000 n Bond breakers are available in different forms, such as liquid, spray, rods, and tape. 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. TILT-CRETE cures the concrete floor or casting slab and top sides of panels once poured. It is applied to the casting slab to function as a bond breaker between the casting slab and the tilt-up or lift-slab panel. The product should be used where appearance is a prime consideration in tilt-up and lift-slab construction. TILT-CRETE concrete cure and bond-breaker is a new, innovative, unique formula of proprietary, reactive organic materials in an aqueous In addition, care should be taken to provide joints at locations of stress concentrations such as (see Figure 1a for unreinforced masonry and Figure 1b for reinforced masonry): Consideration must also be given to the effect of control joint placement on load distribution within the wall. Foundation walls traditionally do not include control joints due to concerns with waterproofing the joint to withstand hydrostatic pressure. When a bond breaker is needed at a construction joint, a curing compound, (0.51 mm), since water repellent coatings can effectively resist water penetration for cracks of this size. Provide Organic Felt bond breaker on top and Expanded Polystyrene (" thick) on sides of retaining wall.

Please let us know here why this post is inappropriate. 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. After studying the way 12,500 American men pee, scientist discovered a revolutionary way to reverse enlarged prostates. Stud Rail Be sure to coat down the side of the pier past the expected depth of concrete cap.

One of my first slab on grades (when I was a real know-it-all rookie) I had plywood separation strips, and I was positive the concrete would shrink away and it would be easy to pull out the plywood strips betcha they are still there That's why I'm asking because I don't really know what to use. Cures concrete casting slab and top of tilt-up or lift-slab panel. Like all construction systems, design decisions significantly influence field performance of the concrete masonry wall system. MASTERSEAL NP1 CAULKIING SEALANT WHITE 10 OZ TUBE (50426722). As an alternative to extending the lintel reinforcement a minimum of 12 in. %PDF-1.4 % Z Tie Holder For walls containing masonry parapets, consider the parapet as part of the masonry wall below when determining the length to height ratio if it is structurally connected by masonry materials. What warranty is offered by the manufacturer? 0 Shear transfer devices such as preformed gaskets or shear keys (such as those shown in Figures 3a, 3d, 3e, 3f, 3h and 3i) may not be necessary when using openings wrapped with reinforcement in wall segments designed to resist the lateral loads applied directly to them plus those transferred from the opening enclosure. Using the same type of detail as for the unreinforced wall would require the control joint to cross the vertical reinforcement, thereby preventing movement and defeating the purpose of the control joint. When a slip plane under the bond beam is used for openings larger than 6 ft (1.83 m), control joints are recommended on both sides of the opening as shown in Figure 2b. However, some designers incorporate shear transfer devices to limit the relative movement between thetwo panels on either side of a control joint, thereby reducing the stress on the joint sealant and providing longer life. 6. :{R?CX6):RO@>{,Xrzh&!csxu48J[lcK9&O7 H-[CG@Y2cbNue9x@UWWw,v88R4 5V4z`}ektG:SLbrnQh~)gkh55p.yijmsOLg@x+f8 ] [4(tUb`fAk`UL!BZPi3 -=b@-np>/9GE]n5@'}gmehn670`CB*C%2*KB]NQmzznmkYLk&or8bf]c"s#=@#IQ(. *Eng-Tips's functionality depends on members receiving e-mail.

Sure Plug - Insertion Tool However, due to congestion in the cell at this location, vertical reinforcement is sometimes placed in the second cell from the opening. WebBond breaker tape shall be an adhesive-backed glazed butyl or polyethylene tape which will adhere to the premolded joint material or concrete surface. <<2F6130032B3F7D4E822F4C36175224FC>]/Prev 134655/XRefStm 1837>> He is an engineer with experience managing and overseeing large civil works construction. Thin Slab Ferrule Insert 30 felt) or coat the top of pier with asphalt mastic. Easy-Lift FD is applied to the concrete casting slab to efficiently prevent the bonding If it rains within 12 hours of application, TILT-CRETE will need to be reapplied. 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. Threaded Inserts TILT-CRETE has excellent stability and does not require continuous mixing throughout the application process; the material must be mixed only prior to application. And 2) Thick applications of bond breaker can result in adhesion of tilt slabs to form slabs, resulting in pop-outs and other defects in the tilt panels. It is placed to ensure that there is no adhesive molecular bond between the surfaces. SHELF LIFE 0000001485 00000 n When the tilt-up panel See TEK 10-3, Control Joints for Concrete Masonry WallsAlternative Engineered Method (ref. However, W. R.

Then this discovery could save your life. Web7. and clean panel appearance. These types of bond breakers are made of crude resins to form the thin film. A proper application is indicated by the presence of a dry-soap feel uniformly apparent to touch over the treated surface. 127 58 Standard Specifications for Loadbearing Concrete Masonry Units, ASTM C90-16a. The non-reactive bond breaker will interact with the concrete surface and generate a waterproof surface. This premium-grade bondbreaker contains organic compounds that react with adjacent to corners of walls or intersections within a distance equal to half the control joint spacing. WebOur backer rod (backstop / bond breaker), is designed to work with all popular sealants including NP1 Polyurethane, a Novalink Polyether, M1, Duralink, glazing sealants and 2023 NATIONAL CONCRETE MASONRY ASSOCIATION. DO NOT DILUTE. %%EOF Table 1 lists recommended maximum spacing of these control joints based on empirical criteria. This keeps the joint weather tight while accommodating small movements.

Stiffback Bracket Out-of-plane shear loads can be transferred by providing a shear key, as shown in Figures 3a, 3d, 3e, 3f, 3h and 3i. 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. I've not used isolation joint for this purpose before (needing to lift the slab). 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. %PDF-1.4 % 0000053803 00000 n Threaded Bar 0000008377 00000 n Membrane forming bond breakers will hold water in the casting slab, and they are formulated to meet ASTM C-309, the standard specification for liquid-membrane-forming compounds.
