HIGH STRENGTH AND WATER IMPERMEABILITY OF CONCRETE AS A FUNCTION OF SURFACE AREA OF AGGREGATE

THE AUTHOR HAS DEVELOPED A NEW APPROACH FOR ANALYZING THE RELATION BETWEEN AGGREGATE GRADATION AND STRENGTH OF CONCRETE. THE METHOD IS APPLIED TO A NUMBER OF DIFFERENT TYPES OF AGGREGATE. THIS RELATION IS A SURFACE AREA FACTOR. THE TOTAL SURFACE AREA OF ALL PARTICLES IN ONE POUND IS DEFINED AS THE "SURFACE AREA FACTOR". SINCE THIS IS A QUANTITATIVE ALTERNATE FOR THE FINENESS MODULUS, THE FORMULAE INCLUDE ONLY THE QUANTITY OF AGGREGATE RETAINED ON NO. 100 SIEVE. SIMPLE FORMULAE ARE PRESENTED FOR THE DETERMINATION OF THE SURFACE AREA OF ONE POUND OF AGGREGATE. THESE FORMULAE ARE USEFUL FOR ANY KIND OF STRUCTURAL CONCRETES USING RIVER AGGREGATE, CRUSHED ROCK OR LIGHTWEIGHT AGGREGATE. PRELIMINARY EXPERIMENTAL RESULTS ARE PRESENTED WHICH SUPPORT THE FORMULAE. NUMERICAL EXAMPLES ILLUSTRATE THE USE OF THE FORMULAE. /TRRL/
