Title: Method and device for testing water resistance of concrete
Inventor: KANDA TORU
IPC: G01N33/38
Filed: 1989-12-20
Abstract: PURPOSE:To test and evaluate the water resistance of even fresh concrete by providing a test container which is filled with the fresh concrete and discharges water entering the container from the top surface from the reverse surface and a water feeding means. CONSTITUTION:The fresh concrete 44 is charged in a membrane 43 firstly. In this state, the high pressure gaseous nitrogen 7 in a gaseous nitrogen cylinder 5 is supplied to a water tank means 1 through piping 6 and the water 3 in a water tank 2 is supplied to between a cylinder 13 and punching metal 41 with specific pressure. Consequently, specific pressure is applied to the flank of the concrete 44 through the metal 41 and membrane 43. No water enters the concrete 44 from the flank because of the presence of the membrane 43. Specific pressure is applied to the top surface of the concrete 44 and the water penetrates the concrete downward from the top surface to flow out on a reverse surface disk 53. Further, the water passes through the disk 53 and a support frame 55 to flow out on a bottom plate 21, and is discharged through drain piping 67. Then water which is collected for a specific time is sampled and metered to evaluate the water resistance of the concrete 44.
