FIELD INVESTIGATION OF CONCRETE QUALITY USING THE WINDSOR PROBE TEST SYSTEM

EXTENSIVE APPLICATION OF THE WINDSOR PROBE TEST SYSTEM HAS BEEN MADE IN INVESTIGATIONS OF IN-PLACE COMPRESSIVE STRENGTHS OF CONCRETE AND IN DETERMINATIONS OF CONCRETE QUALITY. THE SYSTEM DRIVES WITH A CONSTANT ENERGY A STEEL PROBE INTO CONCRETE; THE DEPTH OF PROBE PENETRATION IS A MEASURE OF RESISTANCE TO PENETRATION. THIS PROBE PENETRATION IS THUS INDICATIVE OF COMPRESSIVE STRENGTH. COMPARISONS OF THESE COMPRESSIVE STRENGTHS WITH THOSE OF CORES OR CYLINDERS HAVE BEEN MADE. THE WINDSOR PROBE HAS BEEN USED IN INVESTIGATIONS OF COMPRESSIVE STRENGTHS OF REINFORCED CONCRETE PIPE, HIGHWAY BRIDGE PIERS, ABUTMENTS, AND PIER CAPS WHOSE STRENGTHS WERE IN QUESTION; OF CONCRETE PAVEMENTS WHOSE STRENGTHS WERE SUSPECTED OF BEING WEAKENED BY LIGHTNING STRIKES; AND OF CONCRETE SURFACES DAMAGED BY FIRE. /AUTHOR/
