Description

technical field [0001] The invention relates to the technical field of cement setting time measurement, in particular to a fully automatic cement setting time measuring device. Background technique [0002] The physical and chemical properties of cement directly affect the strength and durability of buildings, and are related to the safety of life and national property. Therefore, the detection of cement performance indicators is of great significance. Among them, the setting time of cement is one of the important parameters of cement performance. The purpose of measuring the setting time of cement is to determine whether the setting time of cement is within the specified range. The setting time of cement can be divided into initial setting and final setting. The time required for the cement slurry to lose its plasticity and fluidity from the addition of water is called the initial setting time. The time required for the cement slurry to completely lose its plasticity and ...

Problems solved by technology

[0006] Cement setting time is a daily routine measurement item in cement plants and central laboratories. The number of test samples is large, and the testers completely rely on manual operations, which require continuous observation and timing, which is time-consuming and laborious. If the setting time of the specimen is too long, it often takes day and night test

Moreover, with the manual measurement method, there are many uncertain factors in the measurement process, which will affect the objectivity of the measurement results.

[0007] These uncertain factors include: the difference in the operating proficiency of the testers; the difference in the environmental conditions of each measurement; due to the interference of the tester's personal factors or external factors, the measurement cannot be carried out according to the specified time of the test.

These uncertain factors will directly lead to deviations in the measurement results

[0008] In addition, there are currently some related patent applications that disclose related technical equipment. This type of device generally has fewer stations, and can only measure one type of cement specimen at a time, and cannot automatically flip the specimen, which cannot fully meet the requirements of the national standard. , making it difficult to achieve intuitive comparison during operation, and because there is no curing box, manual participation is required in the middle, and the degree of intelligence is low
