The main point of cement density determination is to measure the actual weight of cement per unit volume. The classic method is to use the liquid displacement method. When measuring, at a constant temperature, use the volume scale of the thin neck of the Lee's bottle to measure the volume when a certain weight of cement is added, and the cement is added to the Lee's bottle with a certain amount of liquid medium. , and make the liquid medium fully soak the cement particles. According to Archimedes' law, the volume of cement is equal to the volume of the liquid it displaces, so the mass per unit volume of cement is calculated as density. In order to prevent the measured cement from hydration reaction, anhydrous kerosene is used as the liquid medium. Lee's pycnometer is made of glass with strong chemical resistance and low thermal resistance. The finished product is transparent and streak-free, and has sufficient thickness to ensure good crack resistance. The volume is 200-250ml, with a thin neck with a length of 18-20cm and a diameter of 1cm. The scale reading on the thin neck is from 0ml to 24ml, and there should be a 0.1ml scale line between 0-1ml and 18-24ml, under the thin neck There is a drum-shaped enlarged neck. In the process of measuring cement density, kerosene is required to be added between the 0 scale and the 1ml scale line of the Lishi bottle, and the amount of addition is not easy to control; at the same time, during the adding process, kerosene is easy to stick to the inner wall of the Lishi bottle, which is not easy to clean.
