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).
