Fast track concrete technology has been used over the past two decades for overnight highway repairs. Originally, fast track was concerned only with rapid strength gain and workability but little concern was paid to cost and durability of the concrete.
The purpose of this research study is to develop a current improved very early strength (VES) concrete mix, which was accepted by NJDOT in 1996. More than 50 concrete mixes were evaluated for strength, shrinkage, and curing rate (maturity), eventually leading to the development of an optimized VES concrete mix with improved performance characteristics.
The study has developed the new …
