Abstract:
The development and testing of two high early-strength concrete mixes is discussed. For minimal traffic disruption, the fast track concrete developed was used in full-depth repair of jointed concrete slabs on an interstate highway in New Jersey. Type I portland cement and a nonchloride-based hardening accelerator were employed in the production of the fast track concrete. A comprehensive experimental program was implemented for examining the strength gain capability as well as the practicality of these mixes for field implementation.
