Abstract:This paper deals with a rapid air permeability test for site concrete. First, the development of test method is discussed, and the effect of various variables such as capacity of manometer, length of hose, recovery height of mercury head and, depth of test hose, are examined. Secondly, the test is applied to full size specimens, and the relationships between the height of concrete and the strength of cores, carbonation depth and air permeability are discussed. Finally, the developed test method for air permeability of concrete on site is described. Briefly the test method consists of boring a hole of 5 mm in diameter and 40 mm in depth plugging it with a rubber stopper, into which a big injection needle is introduced and connecting it to a manometer. Vacuum is then applied to the system and the recovery speed of mercury head is measured which then represents the air permeability of concrete.
