Performance of Concrete Rehabilitation Using Rapid Setting Calcium SulfoAluminate Cement at the Seattle-Tacoma Airport

Concrete pavement repair is frequently subject to stringent time constraints. Airport repairs do not allow for extended closures to traffic. Generally they cannot halt aircraft movements for days during taxiway or runway repairs. Airport pavement has a limited design life, after which it must be replaced. It must be replaced quickly so that air traffic can resume, and only a few choices are available for a concrete base material. Common Portland cement does not reach structural strength for days. It can be accelerated with organic additives, but this leads to mixes which are difficult to work with, have significant shrinkage and limited life cycle. Another choice is calcium sulfoaluminate (CSA)-base concrete. CSA cement sets within hours, exhibits low shrinkage, high strength and sulfate resistance. It has been used in the United States for a few decades for highway and runway repairs. However, it is still a young technology compared to Portland cement technology and there are few reports on the field durability of CSA-based concretes. Starting in 1995 and for over 10 years, the Seattle-Tacoma airport used CSA-based concrete to repair one of its two runways. Repairs took place at night: Portland concrete panels were replaced by fresh CSA concrete on which aircraft landed by 6 a.m. This report is, to the authors’ knowledge the first attempt at documenting the on-site long term performance of CSA-based concrete originally used for its fast setting characteristics but, as it turned out, may have been used as well for their high long-term durability.
