High Performance Concrete Repair Mortar
PRODUCT DESCRIPTION:
Rapid Set® DOT Repair Mix is a unique dry blend of Rapid Set® Cement and a quality sand. NO CHLORIDES ARE ADDED. When mixed with water, it produces a quality mortar which gains strengths exceeding 3000-psi in 1-hr and 5000-psi in 24-hr. Rapid Set® DOT Repair Mix is ready for traffic and loading within 2 hours. Rapid Set® DOT Repair Mix is similar in color and application to portland cement concrete. Rapid Set® DOT Repair Mix can be extended with a clean, uniform sized aggregate. For improved durability in some geographical areas, Rapid Set® packaged grout, mortar, concrete and DOT repair mixes contain an admixture which produces about 6% air entrainment in the mixed product.

SURFACE PREPARATION:

Roughen surface and remove all unsound concrete. Immediately prior to placement the repair surface shall be thoroughly saturated with no standing water (ssd).
MIX & APPLY:
The working time for Rapid Set® DOT Repair Mix is 10-20 minutes at 70F. Setting time is longer at lower temperatures and shorter at higher temperatures. The working time may be extended by using chilled materials and/or Rapid Set® Set Control®. In cold weather heated materials may be used to accelerate the set and strength development.
Place material quickly and strike off with a screed. Apply desired finish. Begin water curing immediately after final finishing. For more details, contact CTS.
