DETERMINATION OF CEMENT CONTENT OF HARDENED SLAG CONCRETE

A CHEMICAL METHOD WAS DEVELOPED FOR DETERMINING THE CEMENT CONTENT OF HARDENED PORTLAND CEMENT CONCRETE CONTAINING BLAST FURNACE SLAG AS THE COARSE AGGREGATE. THE METHOD IS BASED ON ANALYZING FOR SULFATE AS SO3, AND REQUIRES THAT THIS CONSTITUTENT BE KNOWN FOR THE PARTICULAR CEMENT AND AGGREGATE USED TO MAKE THE CONCRETE. THE RESULTS OBTAINED ARE GENERALLY WITHIN PLUS OR MINUR 0.5 SACKS PER CUBIC YARD OF THE KNOWN CEMENT CONTENT FOR SLAG AGGREGATE CONCRETE CURED FROM 3 TO 7 DAYS. CONCRETE CURED OUTSIDE THIS SPAN OF TIME GAVE RESULTS OF LESSER ACCURACY. THE PROCEDURE IS ALSO APPLICABLE TO CONCRETE CONTAINING GRAVEL AND LIMESTONE COARSE AGGREGATE, BUT THE RESULTS ARE SOMEWHAT LESS ACCURATE THAN THE RESULTS FOR SLAG AGGREGATE CONCRETE. /AUTHOR/
