DESCRIPTION: Rapid Set® V/O REPAIR MIX is a high-performance, polymer-modified blend of Rapid Set® Cement with additives and quality aggregates. V/O REPAIR MIX has been specially formulated to match the color of typical portland cement concrete. Cutting-edge Self-Curing Technology (SCT) means wet curing is not required in most applications. V/O REPAIR MIX is non-metallic and no chlorides are added. Combine V/O REPAIR MIX with water to produce a high quality repair material that is ideal where rapid strength gain, high durability, and low shrinkage are desired. Integral corrosion inhibitor increases protection of embedded reinforcement. V/O REPAIR MIX has a working time of 25 minutes and achieves 2000 psi in 2 hours.
USES: Use V/O REPAIR MIX for general and structural concrete repair, marine applications and formed work. V/O REPAIR MIX is a versatile product that is suitable for horizontal, vertical and overhead applications. V/O REPAIR MIX contains an air-entraining admixture for freeze-thaw durability.
ENVIRONMENTAL ADVANTAGES: Use V/O REPAIR MIX to reduce your carbon footprint and lower your environmental impact. Production of Rapid Set cement emits far less CO2 than portland cement. Contact your CTS representative for LEED values and environmental information.
APPLICATION: Apply V/O REPAIR MIX in thicknesses from 1/4" to 2" (0.6 cm to 5.1 cm). For vertical, small spot repairs, thicknesses up to 6" (15.2 cm) are acceptable.
SURFACE PREPARATION: Surface must be clean, sound, and free of oil, curing compound, dust, mastic and other bond-breakers. Surface must be prepared to a minimum proﬁle of ICRI CSP 3. Mechanically abrade surface and remove all unsound material. Apply V/O REPAIR MIX to a thoroughly saturated surface with no standing water.
MIXING: The use of a power-driven mechanical mixer, such as a mortar mixer or a drill-mounted mixer is recommended. Organize work so that personnel and equipment are in place before mixing. Use clean, potable water. V/O REPAIR MIX may be mixed using 3.5 to 4.0 quarts (3.3 L to 3.8 L) of water per 50-lb (22.7-kg) bag or pail. Use less water to achieve higher strengths. DO NOT exceed 4 quarts (3.8 L) of water per bag or pail. Place the desired quantity of mix water into the mixing container. While the mixer is running, add material. Mix for the minimum amount of time required to achieve a lump-free, uniform consistency (usually 2 to 3 minutes). Do not retemper. Avoid mixers that entrap large amounts of air.
INSTALLATION: V/O REPAIR MIX may be placed using traditional methods. Place and consolidate quickly to allow for maximum finishing time. Use a method of consolidation that eliminates air voids. Do not wait for bleed water. Apply final finish as soon as possible. V/O REPAIR MIX may be troweled, floated, shaved or broom finished. Do not install on frozen surfaces. To extend working time, use Rapid Set® SET Control retarding admixture from the Rapid Set® Concrete Pharmacy®.
COLD WEATHER: Environmental and material temperatures below 70°F (21°C) may delay setting time and reduce the rate of strength gain. Lower temperatures will have a more pronounced effect. Thinner sections will be more significantly affected. To compensate for cold temperatures, keep material warm, use heated mix water, and follow ACI 306 Procedures for Cold Weather Concreting.
WARM WEATHER: Environmental and material temperatures above 70°F (21°C) may speed setting time and increase the rate of strength gain. Higher temperatures will have a more pronounced effect. To compensate for warm temperatures, keep material cool, use chilled mix water, and follow ACI 305 Procedures for Hot Weather Concreting. The use of SET Control retarding admixture from the Concrete Pharmacy will help offset the effects of high temperatures.
CURING: V/O REPAIR MIX does not require water curing or curing compound under moderate conditions at 70°F (21°C). In dry, windy or hot conditions, mist with water to maintain a continuously wet surface until the product has achieved sufficient strength.
YIELD & PACKAGING: One 50-lb (22.7-kg) bag or pail of V/O REPAIR MIX will yield approximately 0.37 ft3.
SHELF LIFE: V/O REPAIR MIX has a shelf life of 12 months when stored properly in a dry location, protected from moisture, out of direct sunlight, and in an undamaged package.
USER RESPONSIBILITY: Before using CTS products, read current technical data sheets, bulletins, product labels and safety data sheets at www.CTScement.com. It is the user’s responsibility to review instructions and warnings for any CTS products prior to use.
WARNING: DO NOT BREATHE DUST. AVOID CONTACT WITH SKIN AND EYES. Use material in well-ventilated areas only. Exposure to cement dust may irritate eyes, nose, throat, and the upper respiratory system/lungs. Silica exposure by inhalation may result in the development of lung injuries and pulmonary diseases, including silicosis and lung cancer. Seek medical treatment if you experience difficulty breathing while using this product. The use of a NIOSH/MSHA-approved respirator (P-, N- or R-95) is recommended to minimize inhalation of cement dust. Eat and drink only in dust-free areas to avoid ingesting cement dust. Skin contact with dry material or wet mixtures may result in bodily injury ranging from moderate irritation and thickening/cracking of skin to severe skin damage from chemical burns. If irritation or burning occurs, seek medical treatment. Protect eyes with goggles or safety glasses with side shields. Cover skin with protective clothing. Use chemical resistant gloves and waterproof boots. In case of skin contact with cement dust, immediately wash off dust with soap and water to avoid skin damage. In case of skin contact with wet cement, wash exposed skin areas with cold running water as soon as possible. In case of eye contact with cement dust, flush immediately and repeatedly with clean water, and consult a physician. If wet cement splashes into eyes, rinse eyes with clean water for at least 15 minutes and go to the hospital for further treatment.
