A FIELD INVESTIGATION OF THE AE-55 AIR INDICATOR
THE RESULTS OF A STATEWIDE EXPERIMENT TO COMPARE THE AE-55 AIR INDICATOR FOR CONCRETE WITH CONVENTIONAL PRESSURE METHODS ARE PRESENTED. THE DATA FROM 835 COMPARATIVE TESTS WITH VARIOUS MATERIALS AND OPERATORS ARE STATISTICALLY ANALYZED AND COMPARED WITH RESULTS OF LIMITED LABORATORY STUDIES PREVIOUSLY GIVEN BY GRIEB AND MATHER (HRB BULL. 176). THE RESULTS OF THE PRESENT STUDY ARE IN AGREEMENT WITH PREVIOUS WORK AND GIVE A FIELD VERIFICATION OF LABORATORY DATA. FROM THE COMPARISON SOME ESTIMATE OF THE RELIABILITY CAN BE MADE, AS WELL AS THE EFFECT OF USING AN UNSCREENED SAMPLE. AS A RESULT OF THIS STUDY THE INDICATOR IS BEING SUPPLIED TO INSPECTORS FOR USE IN CONTROL OF AIR IN CONCRETE. /AUTHOR/
