EFFECT OF RUST ON BOND OF WELDED WIRE FABRIC

THE EFFECT OF RUST ON THE BONDING CHARACTERISTICS OF SMOOTH WIRE FABRIC WAS DETERMINED. TWO STYLES OF FABRIC, TYPICAL OF THOSE USED IN HIGHWAY AND AIRPORT PAVEMENTS, WERE TESTED, EACH WITH THREE DIFFERENT DEGREES OF RUSTING--TIGHT, SCALEY AND PITTED. IN ADDITION SAMPLES OF EACH FABRIC STYLE WERE TESTED IN THE CLEAN CONDITION AND IN A WAXED CONDITION. WITH THE EXCEPTION OF THE WAXED SPECIMENS, ALL BUT ONE FAILED BY TENSILE FAILURE OF THE LONGITUDINAL WIRE AT STRESSES RANGING FROM 82,000 PSI TO 91,600 PSI. ALL BUT ONE OF THE WAXED SPECIMENS FAILED AT THE WELD. WELD FAILURES OCCURRED AT STRESSES RANGING FROM 69,800 TO 80,500 PSI WITH THE NO. 1 GAGE LONGITUDINAL WIRE AND 55,800 TO 63,300 PSI THE NO. 00 GAGE LONGITUDINAL WIRE. REGARDLESS OF THE DEGREE OF RUSTING THE ANCHORAGE PROVIDED BY THE WELDED TRANSVERSE WIRE WAS SUFFICIENT TO DEVELOP THE FULL STRENGTH OF THE LONGITUDINAL WIRE, EXCEPT IN THE ONE CASE MENTIONED ABOVE. THE AMOUNT OF RUST SIGNIFICANTLY AFFECTED THE BONDING CHARACTERISTICS OF THE WIRES-- THE GREATER THE AMOUNT OF RUSTING, THE LESS THE LOADED AND FREE END SLIPS. THE ULTIMATE BONDING CHARACTERISTICS OF THE WIRES CANNOT BE DISCUSSED BECAUSE ALL BUT ONE OF THE UNWAXED SPECIMENS FAILED BY TENSILE FAILURE OF THE LONGITUDINAL WIRE AND DID NOT ACUTUALLY PULL OUT OF THE CONCRETE CYLINDER. /AUTHOR/
