One of the benefits of calcium sulfoaluminate (CSA) cements is that these materials gain strength rapidly, where strength development is often measured in hours instead of days. This property makes these materials desirable for use in temporary, non-reinforced repairs of roadways, airfields, and navigable locks. The rapid repair of these infrastructure elements is critical to transporting supplies into regions devastated by disaster. In these austere environments, potable water may not be available in sufficient quantities to make vital repairs, and the use of impure water in the production of CSA cement-based concrete would be advantageous. However, the hydration products formed by CSA cement are substantially different from those formed by portland cement and may react differently to impurities that water sources may contain. This Thesis investigates the impact of various salts and impure water sources on the early-age strength development of commercially-available CSA cement-based concrete.
