FIELD AND LABORATORY STUDIES OF CONCRETE MIXES FOR THE UEHLING-OAKLAND PAVING PROJECT F-304/14/

THIS REPORT DESCRIBES THE FIELD AND LABORATORY STUDY OF CONCRETE MIXES FOR UEHLING-OAKLAND PAVING PROJECT F-304/14/ CONSTRUCTED IN 1946. THE PRIMARY PURPOSE OF THIS INVESTIGATION WAS TO STUDY THE EFFECT OF ENTRAINED AIR ON THE PROPERTIES OF CONCRETE. THE AGGREGATES USED WERE 30 PERCENT LIMESTONE AND 70 PERCENT SAND-GRAVEL. THE VARIABLES INCLUDED WERE TWO BRANDS OF TYPE I CEMENT, A TYPE IA CEMENT, A REPLACEMENT OF PART OF THE TYPE I CEMENT WITH AN AIR- ENTRAINING NATURAL CEMENT, AND AN AIR-ENTRAINING ADMIXTURE. THE EFFECT OF AIR-ENTRAINMENT ON DURABILITY WAS OVERSHADOWED BY THE LOW QUALITY OF THE LIMESTONE USED. HOWEVER, THE USE OF AIR-ENTRAINMENT REDUCED THE MIXING WATER REQUIRED AND, IN SOME CASES, CAUSED AN INCREASE IN STRENGTH. THE AIR-ENTRAINING NATURAL CEMENT PERFORMED AS WELL IN CONCRETE AS THE TYPE IA CEMENT. THE LIMESTONE USED WAS FOUND TO BE UNSATISFACTORY IN FREEZING AND THAWING, AND ITS USE IN PAVEMENT CONCRETE HAS BEEN DISCONTINUED. /BPR/
