Abstract

The present study, as a part of the WVDOH large scale project on HPC, was directed to evaluate various durability aspects of HPC using West Virginia (WV) sources of materials. A total of 24 HPC mixtures were prepared with different supplementary cementing materials (SCM), such as fly ash, slag, silica fume and metakaolin as single or combined admixtures; normal Portland cement, chemical admixtures, and WV sources of limestone and gravel. Durability evaluations included: electrical indications of chloride penetration, chloride ion diffusion test, freeze-thaw/salt scaling test and physical sulfate attack test.;Results and relationships between the results were discussed. Some conclusions were reached and some recommendations were made.
