Rapid Set® MORTAR MIX PLUS (MMP) is a high-performance, rapid-hardening, multi-purpose, polymer-modified concrete repair material. Durable in wet environments, MMP is a blend of Rapid Set hydraulic cement, advancedadditives, and quality aggregates. MMP has been specially formulated tomatch the color of typical Portland cement concrete. MMP is non-metallic and no chlorides are added. Mix MMP with water to produce aworkable, 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.
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 MMP 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 all personnel
and equipment are in place before mixing. Use clean potable water. MMP
may be mixed using 3 to 4 quarts (2.8 L to 3.8 L) of water per 55-lb
(25-kg) bag for Department of Transportation projects or other critical
applications. For general purpose applications, a maximum of 5 quarts
(4.7 L) may be used. Use less water to achieve higher strengths. For
increased fluidity and workability, use Rapid Set® FLOW Control
plasticizing admixture. Place the desired quantity of mix water into the
mixing container. While the mixer is running, add MMP. Mix for the
minimum amount of time required to achieve a lump-free, uniform
consistency (usually 1 to 3 minutes). Do not retemper.
