LINEAR TRAVERSE TECHNIQUES FOR MEASUREMENT OF AIR IN HARDENED CONCRETE

THE METHOD FOR THE DETERMINATION OF AIR IN HARDENED CONCRETE PERMITS THE EXAMINATION OF 6 X 8 IN. AND 6 X 10 IN. RANDOM PLANE FACE-GROUND HARDENED CONCRETE SPECIMENS WHICH MORE TRULY REPRESENT THE AGGREGATE AND AVERAGE AIR VOIDS IN THE ACTUAL CONCRETE THAN SMALLER SPECIMENS. THE CONSTRUCTION AND USE OF THE INSTRUMENTS ARE DISCUSSED AND RESULTS OF TESTS ARE GIVEN. BECAUSE OF THE TIME AND EQUIPMENT NECESSARY TO MEASURE AIR CONTENT BY MEANS OF THE INTEGRATOR, IT IS NOT ADAPTABLE TO FIELD USE. HOWEVER, AS A LABORATORY TOOL IT PROVIDES A MEANS FOR ACCURATE DETERMINATION OF TOTAL AIR. /PCA/
