Get Traffic & Exposure. thickness widths* slab widths. Polyethylene bond breaker tape is mainly used in joint cavities where the sealant is very shallow or in other situations where it is undesirable for the sealant to stick to a certain surface. 1.02 REFERENCE STANDARDS Except herein modified, concrete work shall conform to the latest requirements/edition of ACI 301, Specifications for Structural . In case joint sealants are attached to the joint filler so that movement is prohibited, they can hardly perform their intended functions to seal the joints against water and debris entry. The reactive bond breaker will react with the concrete and produce crude soap. It is used to ensure that there is no adhesive molecular bond between the two surfaces. E-mail: [emailprotected]. Most bond breakers are designed to provide curing compounds to cure the slabs and precast members because the use of chemical curing compounds prevents the proper functioning of bond breakers. The top section pulls free once the joint has been placed correctly in the wet concrete. And is an important factor for building quality control and development. But the use of chemical curing compounds prevents the proper operation of bond breakers. Definition: (1) adhesion of concrete or mortar to reinforcement or other surfaces against which it is placed, including friction and mechanical interlock; (2) adhesion of cement paste to aggregate; (3) adhesion, cohesion, or both between materials; (4) patterns formed by the exposed faces of masonry units, for example, running bond or Flemish To contact your local W.

PDF No. S.15.07 | Rev. 04/15/21 SEALANT BACKING MATERIAL SELECTION GUIDE I am looking for a bond breaker tape that I can use for hot pours (hot tar). 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. Further, they are applied in the joints in liquid form. A sealer is soft and able to accommodate the concrete slab's expansion and contraction. Bond Description: Brickform #LR-5 Liquid Release Bond Breaker forms a colorless barrier that virtually eliminates concrete build-up on mat-type, texturing tools and thereby keeping them flexible and minimizing wear. Bond breaker tape stops the sealant from adhering to the surfaces and prevents the three-sided adhesion. {{ selectedBranch.City }}, {{ selectedBranch.State }} {{ selectedBranch.PostalCode }}, There are no results matching your search terms, {{ product.defaultVariant.mapPrice.formatted }}, {{ product.defaultVariant.finalPrice.formatted }}, {{deps.UserLocation.selectedBranch.City}}, {{deps.UserLocation.defaultLocation.City}}. 20000 Chonburi, Tel. Once the bond breaker is applied to the surface, then once the concrete is poured, the concrete will develop as its own separate property. This allows membrane release from the bond breaker, into a compressible medium. Repair Mortars Specialty Epoxies & Polyurea Products Surface Retarders Tilt-up Bond Breakers Water Repellents Waterproofing & Damp Proofing. A bond breaker is a separator applied between surfaces of concrete. The bond breaker reported to have been used on the casting slab was a chemical reactive organic curing agent and bond breaker (without wax or hydrocarbon resins). It is waterproof, permanent, flexible, and self-sealing. Questionable areas can also be tested by dropping water on the surface. The strength development of this concrete type must be hence factored in the project sequencing process. Non-extruding versatile offers a minimum of 70% recovery after compression. It avoids compression cracks on tilt-up walls. Pavement Plans and Specifications | Caltrans - California Department of The function of a geotextile bond breaker is to reduce the stresses that can occur if two cementitious pavement layers bond.

Using a bond breaker can extend the life of the formwork. SDS. As shown in figure-2, a bond breaker tape in-between the joint sealant and joint filler is provided to facilitate free movement. In addition, it is applied to the concrete surface to reduce the cracking of the slab due to changes in atmospheric humidity. A bond breaker can be used on deteriorated pavements exhibiting rutting,d cracking from fatigue and freeze/thaw or map cracking due to the expansive pressure of alkali silica reaction. The same Bond Breaker material that was originally used to coat the dowels shall be used to recoat . Bond breakers are civil engineered products that form a membrane between the surfaces of concrete. When bond breakers are applied on a surface it substantially reduces the dynamic loads acts on the concrete, and also enables stripping of concrete members and permits their clean separation from casting slabs or moulds. They can also be water-based or non-water-based products. Use the resulting anticipated movement to determine the correct thickness of the control joint and proper spacing for placement of the joint. Bond breakers allow the concrete to separate from each other without compromising the strength or appearance of the concrete. Which can be cost-effective and time-saving for large structures.

Complies with National AIM, OTC Phase I and II, LADCO, Utah R307-361, CARB SCM 2007, and SCAQMD maximum allowable VOC requirements. Without bond breakers, the joint sealer tears apart to accommodate movement. This cracks may take from as simple hair cracks, which with time, propagates, eventually leading to failure of the concrete member. So that cracks in concrete can be minimized. Bond breakers can be classified into two major groups: membrane-forming and non-membrane forming. ASPHALT EXPANSION JOINT is the original expansion joint filler. Most tapes used as bond breakers are made of polymer films such as PTFE and polyethylene. 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. It is ideal for both horizontal and vertical concrete projects. Please enter your delivery zip code below to determine shipping eligibility: Invalid zip code. In simple language, one is called water-based, and the other is called non-water-based. Along with this growth, the use of bond breakers has also increased. A bond breaker is a substance applied to concrete surfaces to guarantee that there is permanent bonding between the surfaces. DECK-O-JOINT resists acids, alkali, chlorine, etc. German engineers have been successfully using non-woven geotextiles as bond breakers for decades.
