USE OF INFRARED SPECTROPHOTOMETRY IN ACCEPTANCE TESTING MEMBRANE CURING COMPOUNDS FOR CONCRETE

THE USE OF INFRARED SPECTRA GREATLY REDUCES THE NUMBER OF TEDIOUS, LENGTHY WATER RETENTION TESTS (ASTM C-156) THAT ARE CURRENTLY PERFORMED ON WHITE PIGMENTED MEMBRANE CURING COMPOUNDS FOR CONCRETE. BASED ON SAMPLES FROM FIVE DIFFERENT PRODUCERS OVER A THREE-YEAR PERIOD, A REDUCTION IN WATER RETENTION TESTS FROM 293 TO 64 WAS PREDICTED. A SIMILAR REDUCTION IN THE NUMBER OF DRYING TIME AND REFLECTANCE TESTS WOULD BE EXPECTED, IM MOST CASES. THE INFRARED SPECTRA ARE USED TO SHOW THAT THE RESIN AND PIGMENT OF ACCEPTANCE SAMPLES HAVE THE SAME COMPOSITION AS THE RESIN AND PIGMENT OF REFERENCE SAMPLES OF KNOWN PERFORMANCE. THE INFRARED METHOD IS RECOMMENDED FOR ACCEPTANCE TESTING TRANSPARENT MEMBRANE CURING COMPOUNDS AS WELL. /AUTHOR/
