High-Early-Strength High-Performance Concrete for Rapid Pavement Repair

In the construction industry, High Early-Age Strength (HES) concrete was traditionally regarded as a concrete that achieves a loading strength in matter of days rather than weeks. However, in the last 10-15 years, this time has been reduced down to a matter of hours. The required minimum compressive strength is determined on a case-by-case basis depending on the project. In construction applications for structures and dwellings the minimum allowed by the International Building Code is 2500 psi, while in road and bridge construction the minimum requirement is typically 3000 psi, and for airport construction is typically 4000 psi. Due to the accelerated strength gain of HES provided by chemical admixtures, the minimum opening strengths are often reduced since it is expected that the concrete continues to gain strength after the traffic load is introduced. The target of this investigation is high early-age strength concrete for the purposes of road and bridge deck repairs. Chapters in this report include: Materials, Mixture Design, Curing, and Testing Methods; Fresh Properties of HES Concretes; Hardened Properties of HES Portland Cement Concretes; Hardened Properties of HES Rapid Set Cement Concretes; and Comparison of HES Concretes.
