ABSTRACT One or more hydroxyalkylamines having molecular weights ranging from about 48 to about 500 and vapor pressures at 20°C ranging from about 10-4 to about 101 mm. of mercury are employed as the major in- gredient of a corrosion inhibiting composition that itself is mixed into a hydraulic cement slurry. The hydroxyalkylamines provide corrosion protection to iron or steel reinforcing members embedded within the concrete but do not substantially affect the air en- training capacity of the slurry.
