[0002] Cement setting time measuring instrument is a kind of testing instrument, also known as Vicat instrument, which is mainly used to detect the setting time of cement paste and is widely used in the testing of concrete and cement industry. Cement setting time includes initial setting time and final setting time, which are used to characterize the time variation characteristics of cement setting after mixing with water. The setting degree of cement paste is characterized by measuring the depth of free settlement of a standard test rod of specified mass and shape from the surface of cement paste of standard consistency within a specified time. When the free settlement depth of the standard test rod within the specified time reaches the specified initial setting and final setting depths, the age of the cement paste is the initial setting time and final setting time respectively, where the age refers to the time from the moment the cement paste is mixed with water to the moment of measurement.
