PROPORTIONING FLY ASH CONCRETE MIXES FOR STRENGTH AND ECONOMY
A METHOD IS PRESENTED FOR PROPORTIONING FLY WITH CEMENT TO PRODUCE CONCRETE OF EQUAL STRENGTHS AT 28 AND 90 DAYS TO CONCRETE WITHOUT FLY ASH. THE METHOD WAS DEVELOPED BY THE TENNESSEE VALLEY AUTHORITY (TVA) AS A RESULT OF USING FLY ASH IN ALL CLASSES OF CONCRETE FOR THE PAST 12 YEARS. EFFECTS OF DIFFERING PROPORTIONS OF FLY ASH ON WATER REQUIREMENTS, STRENGTH, AND ECONOMY ARE GIVEN. THE EFFECTS OF FINENESS AND CARBON CONTENT OF FLY ASH AND VARIATIONS IN STRENGTH OF CEMENTS ON CEMENT REQUIREMENTS ARE DISCUSSED. COMPARISONS ARE MADE BETWEEN THE CEMENT REQUIREMENTS AS DETERMINED BY THIS METHOD WITH THE CEMENT ACTUALLY REQUIRED BY TESTS FROM THE CORPS OF ENGINEERS, TVA, AND BAYS MOUNTAIN CONSTRUCTION COMPANY. THE COMPARISONS WERE MADE USING AT LEAST NINE DIFFERENT SUPPLIERS OF CEMENT AND EIGHT DIFFERENT FLY ASHES, FOUR OF WHICH WOULD NOT MEET FEDERAL AND ASTM SPECIFICATIONS. /AUTHOR /
