RELATIONSHIPS OF CONCRETE STRENGTH TO MAXIMUM SIZE AGGREGATE

THE CONCEPT THAT CONCRETE STRENGTH IS BENEFITED BY USING THE LARGEST MAXIMUM SIZE OF AGGREGATE PRACTICABLE IS DISPROVED. IT WAS FOUND THAT MAXIMUM STRENGTHS IN BOTH FLEXURE AND COMPRESSION WERE SECURED WITH COARSE-AGGREGATE OF ABOUT 3/4 IN. MAXIMUM SIZE. USE OF COARSER AGGREGATES, IN SPITE OF REDUCTION IN MIXING WATER, CAUSES A REDUCTION IN STRENGTHS. THE CAUSE OF THIS REDUCTION OF STRENGTH WAS SOUGHT IN CONCEPTS THAT GREATER SURFACE AREA FOR BOND AND CROSS-SECTIONAL AREA TO RESIST SHEAR ARE AVAILABLE WITH THE USE OF SMALLER SIZE AGGREGATES.
