Water absorption test method and water absorption test apparatus of the concrete surface

摘要

To evaluate or to elucidate the cause factor, etc. associated with the denseness of concrete surface portion of the actual structures, it is situ measuring the water absorption of the concrete surface of the actual structure. Water absorption test device (1), fixed (V, LL) to the concrete surface or negative (E) mechanical connection by (80) the position of the (2) water absorption test device with (25c, 26c) degassing means Position fixings (3), a detector for detecting the amount of water retained water absorbent chamber (B) of (W) and (90), the measuring device is input the detection result of the detector (91) I have a. Time variation of the water absorption rate (y) is measured by the measuring device and a detector. Based on the water absorption rate was measured at a predetermined elapsed time, a comparison is made of the identification or evaluation factors cause or factor associated with the density of the surface layer of the concrete.
