DESCRIPTION: Rapid Set® LOW-P™ REPAIR MORTAR is a specialty mortar that produces a low permeability, corrosion resistant, fast setting concrete repair material that allows for early opening to traffic. No chlorides are added.
USES: Full and partial depth repair of concrete pavements, bridge deck overlays, elevated deck repairs, parking structures, new slab construction, formed concrete work, and grouting.
ENVIRONMENTAL ADVANTAGES: Use LOW-P REPAIR MORTAR 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.
SURFACE PREPARATION: Concrete bonding surfaces must be clean, sound, and free from any materials that may inhibit bond such as oil, asphalt, curing compounds, acids, dirt and loose debris. Complete surface preparation in accordance with project specifications. Roughen surface and remove all unsound concrete. Immediately prior to placement the repair surface should be thoroughly saturated with water. Standing water and puddles should be removed from the surface.
MIXING: The use of a power-driven mechanical mixer, such as a mortar mixer or a drill-mounted mixer, is required. Organize work so that all personnel and equipment are in place before mixing. Use clean potable water and mix whole bags only. LOW-P REPAIR MORTAR may be mixed using 3.5 to 5 quarts of water per 70-lb bag. Use less water to achieve higher strengths. For cold weather applications, use warm water. CAUTION: Do not add portland cement, lime, fly ash or any other admixtures unless approved by CTS.
COLD WEATHER: Environmental and material temperatures below 70ºF (21ºC) 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 70ºF (21ºC) 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 Rapid Set® SET Control® retarding admixture from the Rapid Set® Concrete Pharmacy® will help offset the effects of high temperatures.
YIELD & PACKAGING: LOW-P REPAIR MORTAR is available nationwide in 70-lb bags. One 70-lb bag of LOW-P REPAIR MORTAR will yield approximately 0.7 ft3. When extended with 50 lbs of 3/8" aggregate yields approximately 0.9 ft3.
SHELF LIFE: LOW-P REPAIR MORTAR 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.
