WEAR TESTS ON CONCRETE USING THE GERMAN STANDARD METHOD OF TEST AND MACHINE

IN PRACTICE, A FLOOR SURFACE MUST WITHSTAND LARGE WHEEL PRESSURES BROUGHT ABOUT BY HEAVY LOADS OF SMALL-WHEELED CARTS BEING ROLLED ACROSS THE FLOOR. A TEST IS NEED TO MESURE THE RESISTANCE OF CONCRETE SURFACES TO WEAR. MUCH WORK HAS BEEN DONE IN THIS COUNTRY BY MEMBERS OF SUBCOMMITTEE III-M OF ASTM C-9 ON CONCRETE AND CONCRETE AGGREGATES AND BY OTHERS TO DEVELOP A TEST METHOD YIELDING REPRODUCIBLE RESULTS. THE GERMANS HAVE RECENTLY DEVELOPED A MACHINE AND METHOD FOR ABRASION TEST WHICH WAS ADOPTED AS STANDARD DIN 51951. THE GERMAN TEST DUPLICATES A PRACTICAL WEAR CONDITION BY ROLLING STEEL BALLS UNDER PRESSURE OVER THE CONCRETE SURFACE. THIS RESULTS IN THE CONCRETE SURFACE BEING SUBJECTED TO ABRASION CAUSED MAINLY BY ROLLING AND SLIDING FRICTION ACCOMPANIED BY SOME POUNDING OR BEATING FORCE. WORK WITH THE GERMAN STANDARD MACHINE USING A SLIGHTLY MODIFIED TEST METHOD IS REPORTED HERE. THE TEST IS SENSITIVE TO DIFFERENCES IN MIX AND CURING PROCEDURES. THE RESULTS ARE REPORDUCIBLE AND EASILY OBTAINED. RESULTS INDICATE THAT ADEQUATE CURING IS ESSENTIAL FOR GOOD WEAR RESISTANCE. IT APPEARS THAT SOME RELATIONSHIP EXISTS BETWEEN COMPRESSIVE STRENGTH AND WEAR RESISTANCE. /AUTHOR/
