Shelf life is 12 months when stored according to <br />the above conditions and cool conditions above <br />+5 °C. <br />1.5 Job Conditions <br />A. Environmental conditions: the material shall not <br />be applied during rain and protect from strong <br />drafts. The application temperature must remain <br />lower than +40 °C, for lower temperature curing <br />time extends & for higher temperature curing time <br />reduces. During application at higher temperatures <br />protect material from direct sunlight.</p> <p>Part 2 – Product <br />2.1 Manufacturer <br /> BETOCRETE-CP350-CI as manufactured by <br />SCHOMBURG GmbH & Co. KG conforms to all <br />requirements of this method statement. <br />2.2 Materials <br /> Powder crystalline waterproofing admixture that <br />used to produce permanently active waterproof <br />concrete <br /> <br />Component: In powder form. <br /> <br />It is supplied in: <br /> <br /> 20 kg bags <br /> <br />1,000 kg big bags</p> <p>1/3</p> <p>08/20</p> <p>2.3 Performance Criteria <br /> BETOCRETE-CP350-CI has the following <br />properties: <br /> Colour: <br />grey <br /> <br />Form: Powder <br /> <br />Density: 1.12 g/cm³ <br /> <br />Application Temp.: ≥ +5 °C <br /> </p> <p> <br /> <br /> <br /> </p> <p>Dosage in ready-mix factory: <br />BETOCRETE-CP350-CI with the aggregate for <br />at least 30 seconds before adding water and <br />cement. Then mix at least for 45 seconds.</p> <p>Part 3 – Execution</p> <p>Dosage in truck mixer on the job site: <br />The addition of BETOCRETE-CP350-CI on site <br />(concrete truck) is not carried out as a powder but <br />as a very aqueous suspension. The required amount <br />of BETOCRETE-CP-350-CI is premixed with water <br />at a ratio of 1:1 (e.g. 3 kg BETOCRETE-CP350-CI <br />per m³ and 3 kg water per m³) using a suitable <br />vessel and stirrer and then completely emptied into <br />the mixing drum of the truck. <br />Dose BETOCRETE-CP350-CI directly into the mixing <br />drum. Mix thoroughly mixed for 1 min per m³ <br />of concrete, but at least 5 minutes. Pour without <br />delay.</p> <p>3.1 General: <br /> Assure that concrete mix design and proposed <br />materials are in compliance with manufacturer’s <br />recommendations. <br />Assure that test batching and material testing, if <br />recommended by manufacturer, has been carried <br />out prior to starting concrete work. <br />Comply with manufacturer’s product data and <br />installation instructions. <br />3.2 Application: <br /> Stir powder crystalline waterproofing admixture in <br />a container provided prior to use, to assure that the <br />mixture is homogeneous specially when stored for <br />longer periods. Assure that the water/cement ratio <br />(w/c) does not exceed 0.55 (powder crystalline <br />waterproofing admixture is included.</p> <p> <br />Dosage range <br /> <br />w/c ratio 0.4–0.5: 0.80 % by weight of CEM <br /> <br />> 0.5–0.55: 0.90 % by weight of CEM <br /> <br />Do not exceed 1.25 % by weight of CEM. <br /> <br /> <br /> <br /> </p> <p>Minimum Cement Content: <br />CEM I: <br />270 kg/m3 <br />CEM II: <br />290 kg/m3 <br />CEM III /A: 380 kg/m3</p> <p>Puzzolanic cements <br />with puzzolan content > 20 %: 300 kg/m3 <br />Granulated slag: <br />max.100 kg/m3 <br />Fly ash: <br />max. 80 kg/m3</p> <p>3.3 Important Advice: <br />• Please ensure that pre-tests were made with all <br />admixtures that will be used in the concrete mix <br />• The addition of a concrete retarder can be <br />necessary when using Portland Cement Type <br />II or III. Suitability tests have to be carried out <br />before usage. <br />• It is rarely possible that <br />BETOCRETE-CP350-CI influences the setting of <br />the concrete. Our product Ruxolith T5 (VZ) has <br />proven as the most effective retarder. <br />• Concrete modified with <br />BETOCRETE-CP350-CI may tend to effloresce <br />depending on the composition. <br />• If the BETOCRETE-CP350-CI was stored at <br />temperatures below +5 °C crystals may form, <br />BETOCRETE-CP350-CI is suitable for usage</p> <p>2/3</p> <p>08/20</p> <p>again after warming up to minimum +15 °C <br />followed by stirring or homogenizing. <br />Suitability tests according to valid standards <br />and norms have to be carried out prior to <br />application.</p> <p>3.4 Cleaning: <br /> Regular water flushing of dispensing equipment <br />will prolong service life and reduce breakdowns. <br />Use REINIT-BM on internal metal surfaces subject <br />to contact with concrete in concrete mixers, <br />batch plants and truck mixers regularly to prevent <br />concrete crust formations. Use ASO-R005 to <br />remove hardened concrete crusts.</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
