THE TESTING OF PULVERIZED FUEL ASH FROM SEVERAL SOURCES SUPPLIED TO ONE SITE

THE CONTROL TESTING OF PULVERISED FUEL ASH FROM ONE SOURCE HAS A SET PROCEDURE, BUT IF THE ASH IS FROM SEVERAL SOURCES AND MIXED IN SITU TO FORM A FILL MATERIAL, CONTROLLING IT HAS ITS PROBLEMS. THE FOLLOWING OUTLINES A METHOD TO OVERCOME THIS USING STANDARD COMPACTION AT FIELD MOISTURE CONTENT AS CONTROL, AND ACCEPTING A PERCENTAGE OF THIS IN THE FIELD DRY DENSITY. USING A 4-IN. SAND REPLACEMENT TEST IN THE FIELD THERE IS ENOUGH MATERIAL RECOVERED TO FILL THE STANDARD COMPACTION MOULD. THIS MATERIAL WHEN RECOMPACTED IS USED COMPLETELY AS THE MOISTURE CONTENT SAMPLE. THE RATIO OF THE IN-SITU BULK DENSITY TO THE RECOMPACTED BULK DENSITY GIVES THE ANSWER ON COMPLETION OF THE LABORATORY TESTS WITHOUT HAVING TO WAIT FOR THE DRYING OUT OF THE MOISTURE CONTENT. /RRL/A/
