Open up to traffic in three to four hours with Rapid Set Latex-Modified Concrete (RSLMC). RSLMC is a Rapid Set Cement based concrete overlay mixture that achieves seven-day strengths in three to four hours. It is easy to use—just add water and aggregates. RSLMC is ideal for bridge deck overlays, elevated deck repairs, pavement repairs, and general projects where low chloride ion permeability, corrosion resistance, and fast strength gain are desired.
