This study is intended to provide guidelines for a future global effort on the development of HPC mixes in West Virginia using several types of available aggregates. The objective of the present study is to explore the performance of two types of mixtures using fly ash and slag, respectively, and the same limestone coarse aggregate, natural sand, and constant water/cementitious ratio. For each type, three mixtures were evaluated, with one of the three being defined according to the WVDOT-DOH specifications as a reference (20% fly ash and 30% slag by weight of total cementitious material), from which we varied the quantity of fly ash or slag by +/-5% to define the remaining two. Both fresh and hardened concrete properties were evaluated, and the parameters of interest were compressive strength, drying shrinkage, freeze-thaw durability and chloride permeability, which were not affected much by using higher fly ash or slag content. However, when using higher quantity of slag (35%), the chloride permeability was reduced by nearly 20%. Thus, in future studies, the mixture designs with higher slag and even fly ash content may provide better performance. The best mixture for each type will serve as a foundation for the future optimizations of HPC mix designs in WV.
