DESCRIPTION: Rapid Set® DOT CEMENT is a high performance, rapid hardening hydraulic cement. Durable in wet environments, DOT CEMENT is a specially formulated blend of Rapid Set® Cement and high performance additives. DOT CEMENT is non-metallic and no chlorides are added. Mix DOT CEMENT with washed concrete sand and stone (ASTM C33 grade) at a 1-2-2 ratio to produce a durable concrete. DOT CEMENT is formulated for long life in freeze-thaw regions. DOT CEMENT can be ready for traffic and loading in 1 hour.
USES: Use DOT CEMENT concrete for the repair of pavement, bridge decks, industrial floors, parking garage decks, freezer floors, formed work, and more. Volumetric mixing equipment may be used for large projects. DOT CEMENT contains an air entraining admixture for freeze-thaw durability.
ENVIRONMENTAL ADVANTAGES: Use DOT CEMENT to reduce your carbon footprint and lower your environmental impact. Production of Rapid Set cement emits far less CO2 than portland cement. Contact your representative for LEED values and environmental information.
APPLICATION: Customize the mix for specific applications. A trial batch is recommended to optimize performance. For small projects, start with one 50-lb (22.7-kg) bag of DOT CEMENT, 100 lb (45.4 kg) of sand, 100 lb (45.4 kg) of 1/4" to 3/4" (0.64 cm to 1.9 cm) stone and about 2.1 gallons (7.9 L) of clean, potable water. Up to 2.4 gallons (9.1 L) of clean, potable water may be used if higher slumps are desired. For calculating volume, the specific gravity is 2.98 g/cm3. Contact CTS technical support for additional assistance, if needed. DOT CEMENT based concrete may be installed in thicknesses from 2" to 24" (5.1 cm to 61 cm). Required thickness will depend on jobsite specifications.
SURFACE PREPARATION: For repairs, application surface must be clean, sound and free from any materials that may inhibit bond, such as oil, asphalt, curing compound, acid, dirt and loose debris. Mechanically abrade surface and remove all unsound material. Apply DOT CEMENT concrete 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 mobile volumetric concrete mixer, is recommended. Mix one 50 lb (22.7 kg) bag of DOT CEMENT with 100 lbs (45.4 kg) of sand and 100 lbs (45.4 kg) of 3/8" to 3/4" (0.64 cm to 1.9 cm) stone and 2.1 gallons (7.9 L) of clean, potable water. Up to 2.4 gallons (9.1 L) of clean, potable water may be used if higher slumps are desired. Do not exceed a slump of 9" measured by ASTM C143 (Standard Test Method for Slump of Hydraulic Cement Concrete). Mix and place material quickly.
PLACEMENT: DOT CEMENT based concrete may be placed using traditional construction methods. Place, consolidate and screed quickly to allow for maximum finishing time. Do not wait for bleed water. Apply final finish as soon as possible. Place material into repair area and strike off with a screed. On flat work, do not install in layers. Install full-depth sections and progress horizontally. Use a method of consolidation that eliminates air voids. Working time is approximately 20 minutes at 70°F (21° C). To extend working time, use Rapid Set® SET Control® retarding admixture from the Rapid Set® Concrete Pharmacy® or cold mix water. DOT CEMENT based concrete may be applied in temperatures ranging from 45°F to 90°F (7°C to 32°C).
CURING: Most materials made with Rapid Set® DOT CEMENT must be water cured. Keep exposed surfaces wet for a minimum of 1 hour. Begin curing as soon as the surface starts to lose its moist sheen. When experiencing extended setting time due to cold temperature or the use of retarder, longer curing times may be required. The objective of water curing shall be to maintain a continuously wet surface until the product has achieved sufficient strength.
Alternative curing methods may be suitable in some applications. Methods include, but are not limited to, the use of surface applied curing compounds conforming to ASTM C309. The material formulator is responsible for the mix design and determining the appropriate curing method.
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, pre-wet substrate (saturated surface dry) and follow ACI 305 Procedures for Hot Weather Concreting. The use of Rapid Set® SET Control® retarding admixture from the Rapid Set® Concrete Pharmacy® will help offset the effects of high temperatures.
YIELD & PACKAGING: Rapid Set® DOT CEMENT is available in 50 lb (22.7 kg) bags, 2000 lb (907.2 kg) super sacks and bulk tankers. In the recommended mix design, one bag of DOT CEMENT will yield approximately 1.8 ft3 of concrete.
SHELF LIFE: DOT CEMENT 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 concrete, 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 concrete splashes into eyes, rinse eyes with clean water for at least 15 minutes and go to the hospital for further treatment.
