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. 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. Threaded Bar Stop Organic Felt or geotextile fabric 6" below top of wall. Similar to concrete masonry veneers, half high concrete masonry unit assemblies are installed with a larger percentage of mortar, which in turn has a larger potential for system shrinkage and therefore cracking potential. This premium-grade bondbreaker contains organic compounds that react with the concrete to Sure Lock Tie Site Map Easy-Lift FD is applied to the concrete casting slab to efficiently prevent the bonding To resist the lateral movement around the slip plane, 24-in. Vibrators The reaction produces a gel in the pores of the concrete which effectively forms a water impermeable barrier. TILT-CRETE is used as a cure and bond-breaker in tilt-up, lift-slab, and precast concrete construction. Both would actually be better. Bond breakers are applied on surfaces that will be eventually joined together since once the concrete is poured, they will be inseparable. To allow longitudinal movement, building paper or other material is installed to break the bond between the grout/mortar and one of the masonry units. H. Hidden in northern Jutland's Rold Forest, some 400km north-west of Copenhagen, is the sprawling bunker complex of Koldrigsmuseet REGAN Vest (The Cold War Museum REGAN West). 0000029616 00000 n 127 0 obj <> endobj Easy-Lift E.

Turnbuckle Form Aligner SHELF LIFE Any dull spots must be recoated. Questionable areas can also be tested by dropping water on the surface. If the water beads-up or forms a bubble and does not penetrate the concrete surface, it is sealed. Any areas accepting penetration of the water must be recoated until a positive seal is achieved. Cast the slab separately from the piles, then set it on the piles. In practice, this can be difficult to determine since some movements are reversible, quick or gradual, but several methods are presented in the following sections to provide guidance in locating control joints. The gaskets are generally available in either PVC, complying with ASTM D2287, Standard Specification for Nonrigid Vinyl Chloride Polymer and Copolymer Molding and Extrusion Compounds (ref. Then finish concrete joint edges. Note that crack control considerations for concrete masonry veneers differ from the guidance presented below. Wall Plug COVERAGE Where the keying action is provided by concrete materials, a four-hour fire rating is provided. They can also be divided into water-based or non-water based products. xrtQP8S@T;`'y$Aq(b 0```%l YC?&(30B@lpLs36PJ/"C2 These details may also be used in unreinforced walls and walls utilizing steel lintels, since the area surrounding the opening is strengthened by the additional reinforcement. Not compatible with hot pour sealants or some chemical sure sealants. 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. Please let us know here why this post is inappropriate. Waler Tie Waler Jack DO NOT FREEZE. Foundation walls traditionally do not include control joints due to concerns with waterproofing the joint to withstand hydrostatic pressure. Two-Hole Erection Anchor 1), for more detailed information. %%EOF Proper application of crack control measures, including control joints when required, can help ensure satisfactory performance of the concrete masonry. Login. When required, control joints should be located where volume changes in the masonry due to drying shrinkage, carbonation, or temperature changes are likely to create tension in the masonry that will exceed its tensile capacity. Sealant Compatible: Works with common sealants. 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. Joint Sealants for Concrete Masonry Walls. I've not used isolation joint for this purpose before (needing to lift the slab). Shelf life under 0000006637 00000 n ft./gal, Coverage will vary due to various amounts of different fillers, extenders, or additives in the concrete mix that can result in the concrete mass and finished surface having a higher than normal porosity and some very porous hotspots. Coverage ratios must be adjusted to compensate for resulting penetration and additional coverage coats required to provide proper surface treatment. Join your peers on the Internet's largest technical engineering professional community.It's easy to join and it's free. For both the curing and bond-breaking applications, once TILT-CRETE is sprayed on the surface, do not track over the slab until the surface is totally dry to touch. WebMop all contact surfaces of concrete and Organic Felt or geotextile fabric with cut-back asphalt. Charcoal Color Closed Cell Polyurethane. Stake Driving Tool WebA bond breaker is a material used to prevent adhesion of the newly placed concrete to the substrate*. Easy-Lift S contains a red fugitive dye to aid in the application process. Bond breakers are normally Provides both curing and bond breaking eliminates need for double inventory and handling. 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. A proper application is indicated by the presence of a dry-soap feel uniformly apparent to touch over the treated surface. When control joints are required, concrete masonry only requires vertical control joints. 4) and that a minimum amount of horizontal reinforcement is provided between control joints as indicated in Footnotes 2 and 3 of Table 1. The empirical method is the most commonly used method of locating control joints and is applicable to most building types. 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. WebCONCRETE-CONCRETE JOINTS BACKER ROD BOND BREAKER 3d = w = 4" Unless Specified Otherwise In The Plans = w = 4" Unless Specified Otherwise In The Plans3 (CONCRETE-CONCRETE JOINTS) Concrete Pavement " to 184" Saw Cut Joint Asphalt Shoulder PavementConcrete Pavement 18" to 4" Saw Cut Joint Asphalt Shoulder Figure 4 shows details of the surface of a typical concrete masonry control joint.
