INFLUENCE OF AGGREGATES ON CONCRETE STRENGTH /IN FRENCH/

AFTER A REVIEW OF VARIOUS THEORIES ON THE INFLUENCE OF AGGREGATES ON CONCRETE STRENGTH, THE VIEW IS EXPRESSED THAT ONE OF THE MOST IMPORTANT FACTORS IN CONCRETE STRENGTH IS THE TOTAL SURFACE AREA OF SAND GRAINS. GIVEN CONSTANT PROPORTIONING AND CONSISTENCY, AN INCREASE IN THE TOTAL SURFACE AREA OF AGGREGATES RESULTS IN REDUCING THE MECHANICAL STRENGTH AND ACCENTUATING SHRINKAGE. THE ADDITION OF GRAVEL TO MORTAR DECREASES ITS STRENGTH BUT NOT AS MUCH AS AN EQUIVALENT ADDITION OF SAND. FORMULAS FOR CONCRETE STRENGTH SHOULD INCLUDE A VARIABLE WHICH IS A FUNCTION OF THE TOTAL AREA AND NATURE OF THE SURFACE (ROUGH OR SMOOTH) OF AGGREGATES. /LCPC(A)/RRL/
