TESTS OF CONCRETES CONTAINING AIR-ENTRAINING PORTLAND CEMENTS OR AIR-ENTRAINING MATERIALS ADDED TO BATCH AT MIXER

SOME OF THE MORE SIGNIFICANT RESULTS ARE PRESENTED WHICH WERE OBTAINED IN EXTENSIVE LABORATORY STUDIES MADE IN CONNECTION WITH THE CONSTRUCTION OF 18 EXPERIMENTAL ROAD PROJECTS, AND IN SEVERAL SEPARATE LABORATORY INVESTIGATIONS CONDUCTED DURING THE PAST SIX YEARS WITH AIR-ENTRAINING PORTLAND CEMENTS, AND WITH AIR-ENTRAINING MATERIALS ADDED AT THE MIXER. CONCRETE SPECIMENS FROM NEARLY EVERY EXPERIMENTAL ROAD PROJECT AND FROM ALL LABORATORY SERIES WERE SUBJECTED TO SCALING AND TO FREEZING AND THAWING TESTS. RESISTANCE TO SCALING, AND TO FREEZING AND THAWING WHILE IMMERSED, WAS MARKEDLY IMPROVED WHEN THE CONCRETE WAS MADE WITH AIR- ENTRAINING PORTLAND CEMENTS, OR WITH AIR-ENTRAINING MATERIALS ADDED AT THE MIXER. /PCA/
