SOME RESEARCHES ON THE PHYSICAL PROPERTIES OF HARDENED PASTES OF PORTLAND CEMENTS CONTAINING GRANULATED BLAST FURNACE SLAG

A PORTLAND CEMENT CLINKER INTERGROUND WITH 4 PERCENT GYPSUM WAS BLENDED, IN DIFFERENT PROPORTIONS, WITH A GRANULATED BLAST FURNACE SLAG WHICH HAD ALSO BEEN INTERGROUND WITH 4 PERCENT GYPSUM. THE FINENESS OF EACH OF THE TWO PRODUCTS FROM WHICH THE BLENDED CEMENTS WERE MADE WAS 3200 CM2/G BLAINE, AND THE BLENDS COVERED THE RANGE FROM 0 TO 90 PERCENT OF THE GROUND SLAG COMPONENT IN STEPS OF 10 PERCENT. PASTES OF THE BLENDED CEMENTS WITH WATER/ CEMENT RATIOS OF 0.22 AND 0.50 WERE PREPARED. THE FOLLOWING PROPERTIES OF THE PASTES STORED AT 25.0 C WERE STUDIED' /1/ THE BLEEDING OF THE FRESH PASTES, /2/ THE NONEVAPORABLE WATER CONTENTS, /3/ THE SPECIFIC SURFACES AS DETERMINED BY WATER VAPOR ADSORPTION, AND /4/ THE CAPILLARY AND GEL PORE VOLUMES, EACH OF THE LAST THREE PROPERTIES WAS DETERMINED AT 7 DAYS, 28 DAYS AND 18 MONTHS. THE RESULTS SHOWED THAT THE SPECIFIC SURFACE AREA DEVELOPMENT WAS GREATEST FOR THE BLENDS CONTAINING ABOUT 50 PERCENT OF THE GROUND SLAG COMPONENT, THOUGH THE NONEVAPORABLE WATER CONTENTS WERE APPROXIMATELY CONSTANT FROM 0 TO 40 PERCENT OF THE COMPONENT AND FELL SHARPLY AS THE PERCENTAGE WAS INCREASED FURTHER. POSSIBLE INTERPRETATIONS OF THE RESULTS ARE DISCUSSED. IT IS CONCLUDED THAT AT LEAST FOR THE PARTICULAR SLAG AND CLINKER STUDIED, THE PROPERTIES OF THE BLENDS CONTAINING UP TO ABOUT 50 PERCENT OF THE SLAG COMPONENT WERE SIMILAR TO THOSE OF THE PORTLAND CEMENT COMPONENT BY ITSELF. /AUTHOR/
