Description

Technical Field

[0001] The invention relates to the technical field of Leigh flasks, in particular to a cement density Leigh flask device. Background Art

[0002] The density of cement is usually measured by the Lee pycnometer method. The measurement principle is to pour cement into a Lee flask filled with a certain amount of liquid medium and allow the liquid medium to fully penetrate the cement particles. According to Archimedes' principle, the volume of cement is equal to the volume of liquid it displaces, so the mass of cement per unit volume is calculated as the density. In order to prevent the measured cement from hydrating, anhydrous kerosene is used as the liquid medium.

[0003] However, the structure of the Leaher flask in the prior art is relatively simple. When used, workers usually need to manually pour cement samples into the Leaher flask. As the material inside the Leaher flask increases, the liquid level in the Leaher flask also rises. At this time, the funnel needs to be manually lifted to prevent the funnel from contacting the liquid and affecting the test results.
