The weighing device is used to weigh the weight, the fixed protective member is placed above the weighing device, the capacity cylinder is placed in the fixed protective member, and the test piece is tied tightly with a fixed rope. When in use, the fixed protective member and the capacity cylinder are placed together on the weighing device, and their mass m1 is read. Water is added until the capacity cylinder is just filled, and the weighing device reading m2 is recorded. The test piece is tied tightly with a fixed rope that does not count the volume or mass, and slowly placed into the capacity cylinder. After the water stabilizes, the test piece is slowly taken out. After all the water in the pores flows back into the capacity cylinder, the mass of the capacity cylinder, the fixed protective member, and the remaining water is read and recorded as m3. The utility model has a simple structure, and the preparation materials are easy to obtain. It can be made of suitable materials according to local conditions, and the cost is low. In addition, the utility model is easy to measure and the measurement results are accurate, which facilitates the measurement of porosity.
