TECHNIQUES FOR NUCLEAR CEMENT DETERMINATION

NUCLEAR TECHNIQUES FOR THE DETERMINATION OF CEMENT CONTENT IN SOIL CEMENT AND CONCRETE HAVE BEEN STUDIED. ACTIVATION ANALYSIS APPEARS TO OFFER A METHOD, THROUGH DETERMINATION OF CALCIUM BY THE FORMATION OF RADIOACTIVE CA-49 OR THE DETERMINATION OF SILICON THROUGH THE FORMATION OF AL-28. EITHER TECHNIQUE IS RAPID AND SIMPLE, BUT THE CALCIUM IS A MORE DIRECT AND REPRODUCIBLE MEASUREMENT. ADDITION OF A STABLE TRACER, MEASUREMENT OF NATURAL RADIOISOTOPIC CONTENT, AND ISOTOPE DILUTION DO NOT APPEAR TO BE AS APPLICABLE AS ACTIVATION ANALYSIS. HOWEVER, UNDER SPECIAL CIRCUMSTANCES, THESE TECHNIQUES MAY BE USEFUL. /AUTHOR/
