NRRA: Reduced Cementitious Material in Optimized Concrete Mixtures

Status:  Complete
Report Date:  03/24/2021

Summary:

This document reports the activities and observations of a research team that performed on-site and laboratory testing of concrete mixtures with reduced cementitious materials content placed in two cells at the MnROAD facility in Albertville, Minnesota. The overall objectives of this research project included investigating the early age characteristics of concrete paving mixes containing reduced cementitious contents as well as their long-term performance. It was observed that while workability was marginal in the mixture proportioned with 470 lb/yd3, all other properties of the test sections were similar to those of the control section.
