• Abstract:
  Many entities currently use permeability specifi cations in portland cement concrete (PCC) pavements and ; structures. For those states using permeability specifi cations, the two test methods generally used are ASTM ; C1202 or ASTM C642. The drawback to these test methods is the length of time it takes to conduct the tests ; and the curing time required to test the concrete. More recently a surface resistivity device has become ; available to test the concrete at 28 days of age with a testing time of about fi ve minutes compared to 56 days ; of age and two days of testing time. ; This project investigated the use of a surface resistivity device as an indication of concrete’s ability to resist ; chloride ion penetration for use in quality assurance (QA) and acceptance of high performance concrete ; (HPC).
