Transition Splice Coupler Web7. Figure 3d shows a grouted shear key. 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. Flat Expansion Joint Foam, 6 rolls (300 Ft). However, structural reinforcement, such as bond beam reinforcement at floor and roof levels that resists diaphragm cord tension, must be continuous through the control joint (see Figure 3g). Wale Bolt Assembly the bonding of subsequent concrete pours. US/MC-SAE Threaded Splice Bar 0000008377 00000 n This premium-grade bondbreaker contains organic compounds that react with the concrete to Another option is to provide a horizontal slip plane between the two materials to accommodate the differential movement. It is intended to provide the most straightforward guidelines for those cases where detailed volume change properties of the concrete masonry are not known at the time of design. ft./gal Sure-Guard Rebar Protector Therefore, it may be prudent to design the lintel to carry the full weight of the wall above it in addition to any superimposed loads. Figures 3f and 3i show smooth dowel bars placed across the control joint to transfer shear.

If, after application of the bond-breaking coat, steel, or concrete-placing operations are delayed longer than two weeks, the bond-breaking coat should be inspected carefully to determine if it still provides 100% coverage. If rain strikes the surface before the coating is dry, any damaged areas must be recoated. After the TILT-CRETE film is dry, normal rain should not affect the surface. First Bond Breaker Coat Application Apply TILT-CRETE to the point of rejection on the casting slab just prior to the placement of reinforcing steel. Spray at right angles to the cure coat spraying pattern. Shelf life under 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. Curing Coat Application Apply TILT-CRETE in a uniform surface film as soon as the surface water has evaporated, immediately after completion of troweling and final finishing operation. WebA bond breaker is a separator applied between surfaces of concrete. See TEK 10-3, Control Joints for Concrete Masonry WallsAlternative Engineered Method (ref. tilt-up and precast construction. Utility Anchors at changes in wall thickness, such as at pipe and duct chases and pilasters. 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. %%EOF Don't rely on synthetic liquid bond breaker.

Bond breakers are applied on surfaces that will be eventually joined together since once the concrete is poured, they will be inseparable. 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. Thereader is referred to TEK 10-4, Crack Control for Concrete Brick and Other Concrete Masonry Veneers (ref. 30 felt) or coat the top of pier with asphalt mastic. The provisions in this TEK assume that units used in the construction comply with the minimum requirements of ASTM C90, Standard Specification for Loadbearing Concrete Masonry Units (ref. As such, the prescriptive crack control recommendations detailed in Table 1 increase the area of horizontal reinforcement and decrease the maximum control joint spacing of half high unit assemblies compared to full height unit assemblies. Bond breakers are available in different forms, such as liquid, spray, rods, and tape. WebSilcoseal Advantage is a water-based bondbreaker and tilt-up cure for use on tilt-up, lift slab and precast construction projects.

As indicated in Table 1 Footnote 1, local experience may justify an adjustment to the control joint spacings presented in the table. For positive bond breaking, it is essential the casting slab be 100% sealed with TILT-CRETE. Visually and physically inspect the slab to witness the entire surface has a definite sheen. 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. A grease-like feel to touch indicates over-application and can result in panel surface discoloration, dusting, surface irregularities, etc. Atlas Easy-Lift E is a high-performance, chemically reactive, water-based cure and bondbreaker for tilt-up and precast 1 0 obj << /Type /Page /Parent 18 0 R /Resources 2 0 R /Contents 3 0 R /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 /Annots 54 0 R >> endobj 2 0 obj << /ProcSet [ /PDF /Text ] /Font << /TT2 28 0 R /TT4 29 0 R /TT6 30 0 R >> /ExtGState << /GS1 33 0 R >> /ColorSpace << /Cs6 31 0 R >> >> endobj 3 0 obj << /Length 2210 /Filter /FlateDecode >> stream 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.

In this scenario, TILT-CRETEs resistance to rain is highly reduced. 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. However, if the opening is completely surrounded by reinforcement as shown in Figure 2c and 2d, the area around the opening is strengthened and control joints can be placed away from the opening. If it rains within 12 hours of application, TILT-CRETE will need to be reapplied. hb```b``b`e`jdd@ AGLdg(1wn78&+$j{nWsFEy-4~XXRS(c)/?rS2cu?_mu:hXsO`5KfZ#weNim4|6mt8lY+v~67b0E8hvnl Sure Lock Strongback Clamp Examine how the principles of DfAM upend many of the long-standing rules around manufacturability - allowing engineers and designers to place a parts function at the center of their design considerations. 0000054060 00000 n Swift Lift Anchors Figure-1: }|aY/?.dId\NfsN=!
