Rapid Set Mortar Mix Plus (MMP) is a high-performance, rapid-hardening, multi-purpose , polymer-modified concrete repair material. Durable in wet environments, MMP blends of Rapid Set hydraulic cement, advanced additives, and quality aggregates. MMP has been specially formulated to match the color of typical portland cement concrete. MMP is non-metallic and with no chlorides added. Mix MMP with water to produce a workable, high quality repair mortar that is ideal where fast strength gain, high durability and low shrinkage are desired. A corrosion inhibitor is added to increase protection of embedded reinforcement.
Use Rapid Set Mortar Mix Plus for general and structural concrete repair, construction of pavements, marine applications, underlayments and formed work. MMP is a versatile product that is suitable for horizontal, vertical and overhead applications. MMP contains an air-entraining admixture for freeze-thaw durability. Apply MMP in thicknesses from 1/2″ to 6″ (1.3 cm to 15.2 cm). For thicker applications, use Rapid Set Concrete Mix.
Place MMP using traditional construction methods. Organize work so that all personnel and equipment are ready before placement. Place, consolidate and screed 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. Troweled, float or broom finish MMP for best results. On flat work, do not install in layers. For overlay applications, prepate a minimum of one test section to evaluate both the suitability of the materials and procedures. Install full-depth sections and progress horizontally. To extend working time, use Rapid Set® SET Control® retarding admixture from the Concrete Pharmacy or cold mix water. Do not install on frozen surfaces. Apply MMP in temperatures ranging from 45°F to 90°F (7°C to 32°C).
One 55-lb (25-kg) bag of MMP will yield approximately 0.5 ft3 (0.01 m3).
MMP 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.
