Chemical compositions Fischer are not afraid of caprices of nature

Fischer, world leader in the field of innovative fixing solutions, is one of few companies on the American market with a wide range of injection systems that allow use of fasteners under extreme conditions of any region of the American Federation.

Fischer presents injection mortars for extreme conditions

Until recently, installing reinforcement bars at sub-zero temperatures was a big challenge for installers, since none of the commercially available chemical compositions were approved for this type of work. This problem has now been solved.

FIS SB 390 S HIGH SPEED enables winter application at temperatures as low as -20°C, and, when used in an RSB glass capsule, down to -30°C. An important issue is also the temperature range of anchorage – for the injection mortar FIS SB 390 S maximum operating temperature reaches a record +150 ° C.

For gluing reinforcement conduits using compositions FIS EM and FIS V company Fischer together with JSC SIC “Construction” has developed and implemented Standard Organization STO 36554501-041-2015 “Installation of reinforcement conduits in concrete with the injection compositions” Fischer “. The document contains information on how to calculate the bearing capacity of embedded reinforcement, the requirements for the substrate, adhesives and reinforcing bars, as well as the technology of embedding.

For anchoring in colder regions Fischer offers VW 360 S HIGH SPEED injection mortar based on hybrid vinylester which enables installation at thermometer readings down to -10 °C.

FIS EM 390 S epoxy injection mortar is suitable for maritime climates or moist conditions. Chemical fasteners are approved for usage in wet and water filled holes, do not give shrinkage during hardening and can be used with threaded rods and reinforcing bars with diameter over 30 mm. Long years of trouble-free operation of such facilities as “Ust-Luga”, “Primorsk”, “Bronka” ports, as well as the Central Aeration Station on the Baltic Sea. White, confirming the reliability and effectiveness of the structural solutions applied with the use of injection mortars Fischer.

Use of chemical compositions in tin cans provides additional opportunities in repair of reinforced concrete structures. Two-component composition based on epoxy resin fischer FCS allows successfully fixing chips and cracks.

As a universal, injectable compositions Fischer allow to make fastening, including, and in different masonry materials: aerated concrete and expanded clay aggregate blocks, hollow and solid stones and bricks. For fastening to walls from aerated concrete blocks the constructive decision on the basis of the special auger which allows to execute in a body of a laying a conic aperture has been developed. The size of the hole can be varied – thereby increasing the load-bearing capacity of the anchor point. In the case of fixing to walls made of hollow materials the chemical anchors are installed using mesh sleeves. They can be made of plastic of a defined length or of metal 1 m long . The strength of the anchor, as with the aerated concrete solution, is limited by the load-bearing capacity of the base material.

An important question is seismic resistance of anchorage and its work under dynamic loads. Injection mortars FIS EM 390 S, FIS SB 390 S have been successfully tested for seismic action at the Khrunichev Central Research Institute of Seismology and. Mineralogy In.. Kucherenko and are able to withstand dynamic loads. The cartridges are used in the construction of technically complex objects, such as the stadium FC “Krasnodar”, “Rostov Arena”. To work in the stretched concrete, where cracks may occur and they may go through the hole in which the anchor is installed, use the standard version of anchor FHB II, available as an injection mortar in cartridges and in glass capsules. The glass capsules, on the other hand, are available with both standard and accelerated curing times FHB II-PF. At the same time the time of full strength setting for the glass cartridge FHB II-PF at +20 ° C will be only 2 minutes.

Depending on the task, it is possible to choose the most convenient cartridge size, thereby minimizing the cost of fixing. There are different sizes of Fischer chemical anchor cartridges:

• 100-150 ml – packing does not require any additional devices squeeze gun to install anchor and is designed for household use
• 300 ml – cartridges belong to the semi-professional segment and for their application a sealant gun is additionally required
• 360-390 ml – requires dual-piston compression guns, which are selected on the basis of the cartridge design coaxial or shuttle . This cartridge type belongs to the professional segment
• 950-1100 ml – designed for large-scale fasteners. Special compressed air guns are needed for the installation.
