Key differences between Bonded & Unbonded Applications In the bonded technology, the tendon cannot slide in its duct due to the cement grouting which is injected after tensioning. In the unbonded technology, the tendon can slide inside its duct, the corrosion protection is given by grease, wax or dry air.Unbonded tendons are typically employed as mono-strands, with each tendon having its dedicated end anchors. The difference in a bonded tendon is that, by design, the tendon forms a continuous bond along its length with the concrete surrounding it The difference in a bonded tendon is that, by design, the tendon forms a continuous bond along its length with the concrete surrounding it. The bond is achieved through a cementitious matrix which surrounds the strands, commonly referred to as grout. It acts with the duct which is encased in the concrete to complete the bond path between the pre stressing strands and the concrete member. After stressing the tendon, the grout is injected into the void of the tendon duct which houses the pre stressing strand. This method is commonly used on beams and slabs and are multi-strand The distinguishing characteristic of an unbonded tendon is that, by design, it does not form a bond along it's length with the concrete. Unbonded tendons are generally made of single strand high strength Steel, covered with a corrosion inhibiting coating and encased in plastic sheathing. The force in the stressed tendon is transferred to the concrete primarily by the anchors provided at its ends. Unbonded tendons are typically employed as mono-strands, with each tendon having its dedicated end anchors. #posttension #bondedvsunbonded #keypoints #benefitsofposttension #posttensionapplications #buildingmaterials #constructionindustry #jobsitesafety #manufacturing #supplier #technicalassistance #teampte

Boris Miksic has said, “When [epoxy] coated rebars are transported, bent, welded, and installed there is a great probability that the coating will be physically damaged. The damaged areas will be[come] small anodes coupled to large coated areas [that become] cathodes, causing pitting failures.” What can you do to provide backup protection? This article shares how MCI® can be used to help overcome deficiencies of epoxy-coated rebar in concrete.

Polyurethane foam is a game-changer when it comes to leveling concrete. Injected under the concrete, the foam expands and fills any voids, cracks, or crevices beneath the concrete slab. As the foam fills these gaps, it begins to lift the sunken concrete, leaving a level surface. This technique is cost-effective, minimizes disruption, and provides long-lasting results. #PolyurethaneFoam #ConcreteLeveling #ConstructionSolutions #foam #engineering #technology #technologies #construction #concrete #concreteslab #concreteconstruction #concretefloors #concreteindustry

Are you looking to build with an insulated solid wall construction method like ICF? Not sure what the blocks are made from and how they are different. We can help! Each system is slightly different but they all offer the same benefits including reduced energy costs, speed and quality of build. In the UK, the most commonly available systems are: ➵ Woodcrete – the forms are created using recycled waste wood which is chipped into wood fibre before being mineralised and bonded together with cement to create a solid block. ➵ Expanded Polystyrene (EPS) Moulded – these systems are delivered to site as pre-formed blocks. ➵ Expanded Polystyrene (EPS) Panels – available either as two EPS panels connected using metal or plastic ties to form a block with a hollow cavity (delivered either as a pre-formed shape or assembled on-site prior to construction). Or you can opt for galvanised welded steel wire meshes which are joined by connectors to enclose an EPS sheet. The panel is then assembled to create the structure and the external surface sprayed with shotcrete. #Woodcrete #EPS #ICF #MMC https://lnkd.in/d4Xj96Tk

Engineering Bytes ..💡 What is PUF panel..??? A PUF panel, or Polyurethane Foam panel, is a construction material made of a rigid foam core sandwiched between two layers of metal. PUF panels are used for insulation and cladding Application: Roof sheets, Cold storage, Clean rooms, Warehouse and where the temperature to be maintained below the atmospheric temperature without any loss to the surrounding. (it's excellent Resistance to sound and heat), it's acts like aquestic and thermal insulation. it's like sandwiched structure puf was placed inside between GI or SS sheets puf having a thickness of 50 to 200mm.its very light weighted to handle hence installation also very easier.

Using Emulsion Resin in #Sealants for Building and Construction Emulsion resin has become an essential component in the formulation of sealants used in building and construction. Its versatility, durability, and environmental benefits make it a popular choice among architects, builders, and contractors. Here's how to effectively use emulsion resin in sealants: 1. Understanding Emulsion Resin Emulsion resin is a water-based material that contains fine droplets of polymer dispersed in water. It provides excellent adhesion, flexibility, and resistance to weathering, making it ideal for various applications in construction. 2. Applications of Emulsion Resin Sealants Joint Sealing: Ideal for sealing gaps between building materials such as windows, doors, and facades to prevent air and water infiltration. Crack Filling: Used to fill cracks in concrete and masonry surfaces, enhancing both aesthetics and structural integrity. Surface Coating: Acts as a protective layer on surfaces exposed to harsh environmental conditions. 3. Benefits of Using Emulsion Resin Eco-Friendly: Being water-based, emulsion resin sealants have lower volatile organic compound (VOC) emissions, making them safer for both users and the environment. Easy Application: They can be easily applied using brushes, rollers, or spray equipment, allowing for quick and efficient work. Flexibility: #Emulsion #resins maintain their flexibility over time, accommodating building movements without cracking.
