Roof Sealing

Inorganic copolymer, the only liquid additive with more than 60 years of expertise for concrete/screed In concrete according to DIN EN 206-1/DIN 1045-2, only concrete admixtures according to DIN EN 934-2 or with general building inspection approval may be used. Our product meets the DIN EN 934-2:2012 standard and is radon gas tight. Product Description Main uses: AREXAL®-liquid X is used to equip concrete for applications in structural and civil engineering with greater durability in structures historically prone to accelerated damage, to provide increased protection against corrosion of concrete steel, and to replace additional external waterproofing. The entire concrete is WD (waterproof) and not just WU (water-impermeable) (WU=DIN= Penetration depth allowed up to 5.0 cm). WU concrete is the abbreviation for water-impermeable concrete. This material and component, as long as there are no cracks or holes, secures the seal against water. It is important to know that in WU concrete, the water penetration depth to be demonstrated can be up to 5.0 cm. With AREXAL®-liquid X, the penetration depth under permanent water pressure of 7 bar is at most 1.8 cm! Typical applications include: heritage conservation, floor slabs, basement construction, highways, airport runways, parking garages, foundations, external walls and floor slabs in the ground, sewage treatment plants, underground vaults, tanks and pits, swimming pools, pressure mats, water storage tanks, tunnels, bridge structures (prefabricated and cast-in-place), curbs and gutters, sidewalks, manholes, catch basins, water parks, dams. Hardened Concrete: higher compressive strength (with the same spread and air pore content) meets the requirements of ASTM C 494, chemical additives for concrete, Type A positive effect on all physical properties waterproof under hydrostatic pressure up to 7 bar, more than 100 psi (0.7 MPa). results in a completely waterproof mass. hard durable surfaces are resistant to sanding or chipping off surfaces are also very resistant to breaking and wear eliminates the formation of condensation in the pore matrix, resulting in excellent frost/thaw resistance Composition and Chemical Components AREXAL®-liquid X is an inorganic, copolymer, liquid additive for concrete, capable of chemically reacting with Portland cement, thereby improving the properties of concrete in all phases of its production, in the fresh state, during curing, and as finished concrete. Sealing Effects The most water-soluble components, calcium hydroxide and calcium-aluminum hydroxide (also referred to as free lime), are converted into the insoluble minerals, tricalcium silicate and tricalcium aluminum silicate. These insoluble minerals grow into the capillaries as very fine micro-crystals. Combined with the micro-pore structure, this results in a concrete mass that can withstand the penetration of water even under the highest pressures. Long-term Durability A large amount of macro-pores (found in normal concrete) are reduced in size to micro-pores in AREXAL®-liquid X concrete. About 3.8% of the mass of AREXAL®-liquid X concrete is occupied by these micro-pores. The micro-pores are hydrophobic and, although the system "breathes," condensation cannot form. This fact, combined with other physical properties of AREXAL®-liquid X concrete, results in a concrete matrix that is extremely durable even under the most adverse conditions. Advantages of AREXAL®-liquid X Fresh Concrete: contains no calcium chloride (or other chloride ions) abrasion resistant (no sanding or wear of the concrete even after more than 40 years) concrete with a lower spread is easier to mix, pump, and compact lower water/cement ratio very cohesive, therefore no voids and shrinkage cavities less water separation (bleeding) and therefore faster finish excellent workability due to better flow and smoothing properties easy to pump AREXAL®-liquid X reduces efflorescence and shows increased resistance to chloride ion penetration - it does not wear out like a coating (AASHTO T259-78) minimal separation during curing significantly reduces shrinkage behavior lower controlled development of hydration heat Corrosion Resistance Independent on-site investigations and laboratory tests show that AREXAL®-liquid X concrete protects reinforcing steel from corrosion and thus permanently prevents concrete spalling! Technical Data Packaging: 10l canister, 25 l canister, 200 l drum, 1000-l one-way container Shelf life: 3 years: protect from frost Dosage: 1 wt-% based on cement weight = 0.9 l/100 kg cement Macrocell Corrosion Test Macrocell corrosion test after 48 weeks of alternating cycles of 4 days immersed in 15% NaCI solution and 3 days dried at 38°C, showed the corrosion current of AREXAL®-liquid X concrete, according to half-cell potential, values of chloride ion content, all of which were below recognized corrosion threshold values. After forty-eight weeks the slabs were destroyed, and no corrosion on the reinforcing steel was discernible. Highway bridge study by Wiss, Janney, Elstner Associates, AG, February 1991, 1998. Installation AREXAL®-liquid X additive is added to the concrete on the construction site, in the ready-mix concrete plant, or in the precast concrete plant. Shake the canister very strongly so that settled crystalline in the container are completely mixed. Procedure Compare the delivery mix with the specification Stir or shake AREXAL®-liquid X in the canister. Continue mixing until a uniformly white consistency is achieved. Add AREXAL®-liquid X to the concrete mixer in the correct dosage (0.9 l / 100 KG cement) Mix AREXAL®-liquid X in the concrete mixer truck at the highest speed for 5 minutes Ensure that no additional mixing water is added. The concrete consistency must be set beforehand. Addition of water at this point will negate the beneficial effects of AREXAL®-liquid X and may void the warranty. AREXAL®-liquid X Specification AREXAL®-liquid X is added to the concrete at a dosage of 0.9 l per 100 kg cement. After adding AREXAL®-liquid X to the mixer of a ready-mix concrete truck, the concrete must be mixed for five minutes at maximum speed. The concrete mix is planned, processed, and cured in accordance with the valid DIN regulations of the respective country. Note: Normal procedures for processing concrete, as described in the ACI Manual of Concrete Practice, are to be followed when handling, placing, processing, and finishing AREXAL®-liquid X concrete. To achieve optimal mechanical properties, full compaction is necessary. Curing procedures, as described in the ACI Manual of Concrete Practice (latest edition), must also be followed. Warranty 25-year warranty on all concrete parts treated with AREXAL®-liquid X. The prerequisite for the warranty is proper application! Maintenance Normal maintenance required for concrete structures also applies to AREXAL®-liquid X concrete.
