PRESTRESSED CONCRETE DURABILITY AND CORROSION

TWO SERIES OF SMALL PRESTRESSED SLABS WERE TESTED FOR FREEZE-THAW DURABILITY, SCALING AND FOR INGRESSING SALT ON CORROSION ON THE ENCASED STRANDS. TAP WATER, CALCIUM CHLORIDE AND MAGNESIUM SULFATE SOLUTIONS WERE USED. THE RESULTS OF THE TESTS ARE REPORTED. MORTAR BARS, WITH VARYING COVER OVER THE STRANDS WERE ALSO TESTED BY SUBMERGING THEM IN SALT SOLUTIONS. ALTHOUGH THE STRANDS WERE WETTED BY THE SOLUTION, NO CORROSION OCCURRED. CLEAN STRAND WIRES WERE EXPOSED TO THE THREE SOLUTIONS BY TOWEL WICKS. CALCIUM CHLORIDE WAS THE MOST CORROSIVE, FOLLOWED BY MAGNESIUM SULFATE AND WATER. /AUTHOR/
