In addition, elements in such environments face an increased risk of carbonation. <br />To provide long-term protection for these surfaces, mineral waterproofing slurries with OS5b certification <br />in accordance with DIN EN 1504‑2 are used. AQUAFIN®‑OS meets these requirements and offers reliable <br />protection against harmful environmental influences.</p> <p>UV-resistant <br />Protects against carbonation</p> <p>Learn more about <br />the product</p> <p>Protects against chloride ingress</p> <p>Properties</p> <p>Material properties</p> <p>• CO₂ diffusion barrier</p> <p>Product components <br />Base material <br />Consistency <br />Tensile adhesion strength DIN EN 1542 <br />Rainproof</p> <p>2 component system <br />Polymer-mortar combination <br />Filler consistency <br />≥ 0.8 N/mm² <br />4 hours</p> <p>Crack bridging DIN EN 1062-7</p> <p>static: Class A4 (2.0 mm) at +20 °C <br />dynamic: Class B2 at -20 °C and after 2000 h of UV <br />weathering: 0.10 - 0.15 mm (1000 cycles) Procedure B <br />Class I > 50 m <br />> 200 m</p> <p>• Chloride-resistant <br />• Dynamic crack bridging at -20 °C <br />• Permeable to water vapour</p> <p>Water vapour permeability, SD <br />CO₂ permeability, SD</p> <p>Areas of application <br />• OS5b surface protection system <br />• Protective coating against chloride attack and carbonation according to DIN 1504-2</p> <p>Mixing</p> <p>• Reinforced concrete elements in high-traffic areas, e.g. paved multi-storey car parks, <br />bridge decks and retaining walls</p> <p>Mix ratio, component A <br />Mix ratio, component B <br />Mixing time <br />Maturing time</p> <p>• Areas without traffic</p> <p>Application</p> <p>• Renovation and protection of concrete surfaces prone to cracking <br />• For newbuild and renovation</p> <p>Material number</p> <p>Package type</p> <p>Colour</p> <p>Units / pallet</p> <p>Pc/package</p> <p>201403001</p> <p>30 kg, set (2 component)</p> <p>grey</p> <p>-</p> <p>-</p> <p>A-component: 20 kg bag</p> <p>50</p> <p>1</p> <p>Substrate/application temperature <br />Pot life <br />Method of application, max. layer thickness per <br />application step <br />Consumption after OS5b and EN 1504-2 <br />Consumption pro m² and mm layer thickness</p> <p>B-component: 10 kg canister</p> <p>50</p> <p>1</p> <p>Overcoat after</p> <p>2</p> <p>2 parts by weight (powder) <br />1 weight fraction (fluid) <br />approx. 3 minutes <br />approx. 2 minutes</p> <p>approx. 5 - 30 °C <br />approx. 30 minutes <br />up to 3 mm</p> <p>approx. 3 hours</p> <p>approx. 5.5 kg/m² <br />approx. 1.8 kg</p> <p>3</p> <p>i</p> <p>RELIABLE PROTECTION <br />AGAINST CONCRETE CORROSION</p> <p>AQUAFIN-OS provides proven protection <br />against chloride, carbonation and damage <br />caused by de-icing salts. When used as a <br />waterproofing treatment, it prevents water <br />ingress and the penetration of substances that <br />damage concrete. AQUAFIN-OS extends <br />the service life of the concrete structure.</p> <p>Concrete protection with AQUAFIN®-OS <br />Reinforced concrete can be protected as follows, thereby extending its service life:</p> <p>In reinforced concrete structures, the concrete absorbs <br />compressive forces, whilst the reinforcing steel is <br />responsible for withstanding tensile stresses.</p> <p>The rust products that form on the reinforcing steel <br />increase in volume, leading to cracks, spalling <br />and ultimately to the failure of the concrete cover.</p> <p>To ensure that the steel remains permanently protected, <br />sufficient concrete cover and the natural <br />alkalinity of the concrete are crucial. As long as the <br />pH value of the concrete is sufficiently high, <br />the steel remains in a passive state and is protected <br />against corrosion.</p> <p>Effective surface protection against water and <br />ingress of O2, CO2 and chlorides is, therefore, <br />crucial to prevent corrosion, extend the service life of <br />the structure and avoid costly repairs.</p> <p>CO2 introduced via water and moisture leads to <br />carbonation processes and a drop in pH value. If the <br />pH value falls below a critical threshold, the steel loses <br />its protective passivation. If oxygen then reaches the <br />reinforcing steel via moisture transport, oxidation <br />processes can begin. The situation becomes particularly critical when chloride ions (XD, XS) are present: they <br />significantly accelerate corrosion.</p> <p>pH</p> <p>Keep the pH level high = A high pH level protects the reinforcing steel <br />Reducing water ingress = Less water ingress means fewer substances that <br />damage concrete</p> <p>Cl-</p> <p>R educing chloride ion migration = Oxidation and depassivation processes <br />occur more slowly <br />Protecting the concrete cover = The greater the concrete cover, the better <br />the reinforcing steel is protected against oxidation</p> <p>-</p> <p>CI</p> <p>i</p> <p>Mechanical (XM) and chemical <br />exposure (XA) can damage the concrete <br />cover. Similarly, freeze-thaw cycles (XF) <br />can have an effect, particularly in combination with de-icing agents.</p> <p>H2O</p> <p>CO</p> <p>2</p> <p>4Fe + 3O2+ 6H2O → 4Fe(OH)3 <br />Ca(OH)2 + CO2 → CaCO3+ H2O <br />Depassivation and oxidation lead to corrosion of reinforcing steel</p> <p>4</p> <p>5</p> <p>Concrete protection in underground car <br />parks and paved multi-storey car parks <br />In multi-storey car parks, concrete structures are subjected to severe <br />stress from de-icing salts during the winter months. In the plinth areas, <br />there is spray damage, whilst in the floor areas, water containing <br />chlorides runs off.</p> <p>The DBV guidance note on <br />multi- storey car parks and <br />underground car parks offers an <br />alternatve to a certified surface <br />protection system in accordance <br />with OS5b. It describes waterproofing <br />in accordance with DIN 18533 for <br />water-permeable road surfaces.</p> <p>i</p> <p>In the case of paved car parks, the chlorides seep into the subsoil, run <br />off the foundations or accumulate there. <br />OS5b surface protection coatings can protect these areas against the <br />ingress of chlorides and also against CO2 ingress.</p> <p>System design in accordance with DIN EN 1504-2 | OS5b</p> <p>Area <br /> <br /> <br /> </p> <p>AQUAFIN®-RB400</p> <p>AQUAFIN®-OS</p> <p>ASOCRET®-M30</p> <p>AQUAFIN®-PRIMER</p> <p>System design in accordance with DIN 18533</p> <p>Area <br /> <br /> </p> <p>AQUAFIN ® -PRIMER <br />2 AQUAFIN ® -OS, applied in two coats <br />3 Protective layer to prevent damage <br />1</p> <p> <br />Sealing cove <br />1 AQUAFIN ® -PRIMER <br /> <br />4 ASOCRET® -M30 <br /> <br />2 AQUAFIN ® -OS, <br />applied in two coats</p> <p>AQUAFIN ® -PRIMER <br />AQUAFIN ® -RB400, <br /> applied in two coats <br />3 Protective layer to prevent damage <br />1</p> <p>2</p> <p>Sealing cove <br />1 AQUAFIN ® -PRIMER <br /> <br />4 ASOCRET® -M30 <br /> <br />2 AQUAFIN ® -RB400, <br />applied in two coats</p> <p>2</p> <p>2</p> <p>1</p> <p>1</p> <p>4</p> <p>4</p> <p>3</p> <p>6</p> <p>3</p> <p>7</p> <p>The SCHOMBURG Group develops, <br />produces and distributes building product <br />systems for the areas of: <br />• Building waterproofing/repair <br />• Tile/natural stone/screed laying <br />• Floor protection/coating systems <br />SCHOMBURG has been recognised in <br />the market for over 85 years nationally and <br />internationally for its development expertise. <br />Building product systems that are produced <br />in-house are highly prized around the <br />world.</p> <p>T: 22/26</p> <p>SCHOMBURG GmbH <br />Aquafinstraße 2–8 <br />D -32760 Detmold (Germany) <br />Phone + 49 - 5231- 953 - 00 <br />Fax <br />+ 49 - 5231- 953-333 <br />www.schomburg.com</p> <p>22/26 NT/JoZ</p> <p>To meet the demanding requirements <br />of an ever-changing market, we <br />continuously invest in the research and <br />development <br />of new and already existing products. <br />This guarantees an ever increasing product <br />quality to the satisfaction of our customers.</p> <p>Changes reserved.
