    New Test Method for Standard Test Method for Determining pH of Lightweight Aggregate for Use in Evaluating Corrosion Potential

    WK45540

    1. Scope

    1.1 This test method describes the procedure and apparatus for determining a pH value to evaluate the corrosion potential of lightweight aggregates conforming to Specification C330/C330M by use of a pH meter. 1.2 The principal use of the test is to supplement soil resistivity measurements to identify conditions under which the corrosion of metal in the lightweight aggregate may be sharply accentuated.

    This standard is needed to establish pH test methods for coarse graded lightweight aggregate in laboratory conditions. The current laboratory test method used material passing the #10 sieve and is not consistent with field measurements of coarse graded lightweight aggregate in field testing.
