USE OF CALCIUM CHLORIDE IN PRESTRESSED CONCRETE

ALL THE LABORATORY TESTS SHOW THAT WET STEAM CURING WITH THE ADDITION OF CALCIUM CHLORIDE ALWAYS RESULTS IN CORROSION OF THE HARD DRAWN STEEL WIRES. THIS IS SHOWN TO BE ELECTROLYTIC CORROSION. CURING IN HOT WATER WITH CALCIUM CHLORIDE DOES NOT PRODUCE SUCH SEVERE CORROSION. NATURAL OR NORMAL CURING WITH CALCIUM CHLORIDE HAS BEEN ALSO FOUND TO GIVE RISE TO ELECTROLYTIC CORROSION, THE SEVERITY OF THE CORROSION VARYING GREATLY FROM ONE SPECIMEN TO ANOTHER. STEAM CURING, WITHOUT ANY CALCIUM CHLORIDE HAS NEVER RESULTED IN THE CORROSION OF THE WIRES AND CAN BE RECOMMENDED WITH CONFIDENCE. /AUTHOR/
