THE OPTIMUM COURSE AGGREGATE CONTENT OF CONCRETE

THE BEST PROPORTIONS IN WHICH TO COMBINE ANY GIVEN COARSE AND FINE AGGREGATES ARE CONSIDERED WITH PARTICULAR REFERENCE TO CONCRETE MIX DESIGN. EARLIER WORK, WHICH WAS RESTRICTED TO 3/4 IN. MAXIMUM SIZE OF AGGREGATE AND USED THE COMPACTING FACTOR TEST TO INDICATE THE WORKABILITY OF THE CONCRETE, IS EXTENDED TO 3/8 IN. MAXIMUM SIZE OF AGGREGATE USING THE VEBE CONSISTOMETER TEST. IN ADDITION TO EXTENDING THE RANGE OF THE CURVES FOR USE IN MIX DESIGN, THE PRESENT WORK SHOWS THAT THE OPTIMUM SPECIFIC VOLUME RATIO OF COARSE AGGREGATE FOR THE VEBE CONSISTOMETER TEST IS SIMILAR TO THAT FOR THE COMPACTING FACTOR TEST. THIS IS A MOST IMPORTANT RESULT SINCE IT SHOWS THAT THE APPLICATION OF THE CONCEPT OF PARTICLE INTERFERENCE IS NOT RESTRICTED TO THE COMPACTING FACTOR TEST. /RRL/A/
