FIELD AND LABORATORY STUDIES OF CONCRETE MIXES FOR THE FAIRMONT-OSCEOLA PAVING PROJECT

THIS IS THE FINAL REPORT OF THE INVESTIGATION PERFORMED TO PROVIDE INFORMATION CONCERNING THE USE OF TYPE I AND I-A PORTLAND CEMENTS. EXPERIMENTAL SECTIONS WERE CONSTRUCTED ON US 30-A, FAIRMONT-OSCEOLA PROJECT IN 1947. BOTH LABORATORY AND FIELD TESTS WERE MADE. THE FOLLOWING CONCLUSIONS WERE DRAWN FROM THIS INVESTIGATION' 1/ THE USE OF TYPE IA CEMENT REDUCED THE MIXING WATER REQUIREMENTS AND THE COMPRESSIVE STRENGTH SLIGHTLY, 2/ CONCRETE SPECIMENS PREPARED WITH TYPE IA CEMENT WERE MORE RESISTANT TO FREEZING AND THAWING THAN THOSE PREPARED WITH TYPE I CEMENT, 3/ LABORATORY AND FIELD TESTS PROVED CLASS 47-B CONCRETE TO BE EFFECTIVE IN CONTROLLING CEMENT-AGGREGATE REACTION, 4/ NO SIGNIFICANT DIFFERENCE COULD BE FOUND BETWEEN SECTIONS CONTAINING TYPE I AND TYPE IA CEMENTS AFTER 18 YEARS OF FIELD SERVICE, AND 5/ THE LIMESTONE USED WAS FOUND TO BE UNSATISFACTORY IN FREEZING AND THAWING. ITS USE IN CONCRETE HAS BEEN DISCONTINUED. /BPR/
