AIR PRESSURIZED BLEEDING MEASUREMENT DEVICE

摘要

In the present invention, provided is a pneumatic bleeding measuring device comprising a container which stores samples of porous materials to test bleeding inside; a pressurizing plate which is installed on the upper part of the container to vertically pressurize the sample downward; a pressure container which is connected to the upper part of the container and stores compressed air to supply a certain amount of air pressure to the upper part of the pressurizing plate in the container; a displacement measuring part which is installed on the upper part of the container and measures displacement of the pressurizing plate when air pressure is pressurized to the pressurizing plate; and a pressure measuring part which is installed on the lower part of the container and measures pressure pressurized to the sample when air pressure is pressurized to the pressurizing plate.
