CONCRETE FOR LONG-TIME SERVICE IN SULFATE ENVIRONMENT

DATA ON CONCRETES SOAKED CONTINUOUSLY IN A 2.1 PERCENT SODIUM SULFATE SOLUTION AND ALTERNATELY SOAKED AND DRIED SERVED FOR PREDICTING SERVICE LIFE. SIXTEEN OUT OF 19 CONCRETES MADE WITH TYPE V AND II CEMENTS SHOWED LIFE EXPECTANCIES OF LESS THAN 50 YEARS. CONCRETES CONTAINING DIFFERENT POZZOLANS SHOWED A SPECTRUM OF EFFECTS RANGING FROM DELETERIOUS TO HIGHLY BENEFICIAL. ONLY 6 OUT OF 33 POZZOLAN CONCRETES HAD LIFE EXPECTANCIES OF LESS THAN 50 YEARS. FLY ASH, PUMICE, AND TWO CALCINED PRODUCTS MARKEDLY IMPROVED SULFATE RESISTANCE. SEVEN OF 11 CONCRETES HAVING A LIFE EXPECTANCY IN EXCESS OF 100 YEARS, SOME POSSIBLY UP TO 200 YEARS, CONTAINED FLY ASH. REVISION OF PRESENT DAY SPECIFICATIONS FOR SULFATE RESISTING CONCRETE IS RECOMMENDED. /AUTHOR/
