PRODUCT DATASHEET

DESCRIPTION: Rapid Set® LOW-P™ Cement is a low permeability, corrosion inhibiting, fast-setting hydraulic cement. When mixed with water and aggregates, Low-P Cement produces concrete mixtures with unparalleled performance and ease of use. The finished Low-P Cement concrete exhibits exceptional long-life durability in harsh freeze-thaw conditions.

APPLICATIONS: Low-P Cement is ideal for fast-track bridge deck overlays, pavement repairs, elevated deck repairs, parking structures, marine structures, and other projects where low chloride ion permeability, corrosion resistance, and fast strength gain are desired. Low-P Cement is superior to portland cement latex modified concrete, low slump concrete, microsilica/silica fume concrete, and polyester concrete.

ENVIRONMENTAL ADVANTAGES: Use LOW-P 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 CTS representative for EPD, LEED values and other sustainability information.

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. Roughen surface and remove all unsound material. Apply Low-P Cement concrete to a thoroughly saturated surface. Standing water and puddles should be removed from the surface. Scrub coats or brush-in coats are not required.

MIXING: Low-P Cement concrete mixes may be batched using continuous volumetric mixer equipment or a weight batch mixer. Organize work so that all personnel and equipment are in place before mixing. Use clean potable water. Working time is approximately 15 to 20 minutes. CAUTION: Do not use additional fly ash or microsilica additives, or pozzolonic materials.

PLACEMENT: LOW-P Cement may be placed using traditional methods. Organize work so that all personnel and equipment are ready before placement. Place, consolidate, and screed quickly to allow for maximum finishing time. Do not wait for bleed water. Apply final finish as soon as possible. Low-P Cement concrete may be troweled, floated or broom finished. Use a method of consolidation that eliminates air voids. Roller and truss screeds can be used for small overlay placements. Self-propelled screed/finishing equipment should be used for all large applications. Patching and small overlay work may require additional internal vibration. Straight edge or bull floats can be used directly behind screed/finisher equipment to ensure closure of concrete surface. Surface retardants or water misting should be used to reduce evaporation. Broom or tine the concrete as soon as the surface can hold the finish applied. Do not install on frozen surfaces.

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 retarding admixtures will help offset the effects of high temperatures.

CURING: For overlays, the surface should be covered promptly after final finishing with a single, clean layer of wet burlap. Immediately following the covering of wet burlap, a layer of clear polyethylene film should be placed over the wet burlap. Patches can be water cured by maintaining a moist sheen on the surface. The curing layers should remain until the concrete has reached the strength desired. Depending on temperature and specified strength, this will usually be within 1 to 3 hours after final finishing. During this period, apply more water, as needed, to keep the entire concrete surface continuously wet.

FIELD TESTS: It is recommended to conduct field test panels at the jobsite using the prepared substrate and the approved LOW-P Cement concrete mix design to determine actual field performance and suitability for the intended use.

AVAILABILITY: Low-P Cement is available nationwide in 2000-lb bulk bags and 50-lb bags.

STORAGE & SHELF LIFE: LOW-P 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 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.
