Concrete Electrical Conductivity Test

(Return to Cement Hydration and Degradation Modeling Software)

The purpose of this form is to compute the results of a bulk electrical conductivity of concrete (ASTM C1760) test and estimate an equivalent response in rapid chloride permeability (RCP) testing (ASTM C1202). The RCPT result is adjusted for the size difference (if any) between specimens in the two tests, assuming that the C1202 test is always conducted on 95.25 mm diameter x 50.8 mm long cylinders. To perform the computations, the user fills in the input fields and the results are updated when an input field is changed or upon request by clicking on the Compute usa-button. Please note that per the C1760 standard, the input measured current is in units of milliamps (mA).
