Rapid Set® Cement is the primary component of dozens of cements, concrete, mortars, and grouts developed for specific applications. Since we (CTS Cement Manufacturing Corp.) introduced the product in the mid-1970s, state transportation departments have consumed more than 2 million tons for bridge and highway panel replacement, partial- and full-depth pavement rehabilitation, and emergency repairs. All but four allow Rapid Set® products.
Rapid Set® isn’t portland cement, though, so you can’t use ASTM C150 (Standard Specification for Portland Cement) to write a specification. That’s why ASTM C1600 (Standard Specification for Rapid Hardening Hydraulic Cement) was introduced in 2009. We recommend a prescriptive rapid-strength concrete specification based on ASTM C1600 cement and adding maximum allowed shrinkage to your other concrete performance requirements (e.g., freeze-thaw, permeability, etc.).

The cement shall be Rapid Set® cement manufactured by CTS Cement Manufacturing Corp.
The cement shall meet the requirements of ASTM C1600 – VRH (very rapid hardening).
Given how detrimental shrinkage is to concrete’s long-term durability, states have begun doing just that. Here's an example:
