New Test Method for Test Method for Water-Soluble Nitrite in Hardened Concrete

1. Scope

This test method covers the determination of water-soluble nitrite concentration in hardened hydraulic-cement concrete. The method requires experience with chemical analysis and should be done by a chemist or under the direction of a chemist.

Keywords

corrosion inhibitor; calcium nitrite;

Rationale

Calcium nitrite is a commonly used corrosion-inhibiting admixture for use in hydraulic-cement concrete. Specifying agencies often require that the dosage of nitrite-based corrosion inhibitor in hardened concrete be confirmed.

The title and scope are in draft form and are under development within this ASTM Committee.
