CTS Manufacturing Corp. has now developed a rapid setting, low-to-zero shrinkage concrete. Rapid Set cement is a low-shrinkage cement. It is a sulfate-resistant product, which further improves its durability. Additionally, Rapid Set cement has a low carbon footprint due to its chemistry. CTS has now developed a one-component, portland-free cement that exhibits near zero shrinkage at 60 days. Rapid Set cement uses the same expansive CSA compound that is found in Type-K. It shrinks dramatically less than Portland based products. This is caused by the combination of three unique characteristics:
- The cement contains drastically reduced amounts of silicates, compared to Portland cement. Silicates are generally responsible for high shrinkage in Portland cements.
- The water required for concrete workability remains chemically bound to the structure of the concrete, instead of evaporating and causing shrinkage.
- The fast setting nature of the cement allows the onset of a slight, early expansion period akin to that observed in Type K but much smaller in magnitude. Shrinkage occurs following this slight expansion to a near-zero final dimensional change.
The cement is not accelerated with any organic additive, which alleviates any concern about the long-term stability of organic molecules. It is a strictly inorganic cement that has been shown in fatigue tests to last more than 100 years.
