Development of Fast-track Concrete-- 2

Résumé du livre

The project described herein pertains to the development of very high early strength concrete, herein referred to as fast track concrete, for rapid repair of highway pavements. This project is a sequel to an earlier study. The objective of the former project was to develop the base mix design for the fast track concrete, establish in-place field monitoring procedures, and demonstrate the fast track technology in actual field applications. The scope of the earlier project was limited to a single cement brand and type. The objective of the study presented here was to explore the capability of Portland cement types I and III in achieving fast track properties. In doing so the project involved development of fast track concrete with a number of different cement brands currently used in New Jersey. The concrete developed in this project will be employed in full-depth repair of jointed concrete pavement slabs.
