Pre-packaged corrosion inhibitor

MCI Grenades are water-soluble pouches of the companion 2006 NS migrating corrosion inhibitor, substituting as needed for doses of the MCI 2005 liquid admixtures. The Grenades are sized to treat 1 yard of concrete. Urgent field conditions aside, the company notes, the pouches afford concrete producers and their customers a convenient option “added onsite and safely handled despite their high pH since they are packaged in water-soluble film that does not dissolve until mixed with water.” — Cortec Corp., St. Paul, Minn., 800/426-7832;
