Description

A concrete online detection method and system

Technical Field

The invention belongs to the technical field of material detection, and in particular relates to an online detection method and system for concrete.

Background Art

Concrete is one of the most important civil engineering materials in contemporary times. Slump is an important indicator of concrete workability. It is used to measure the fluidity of concrete mixture and thus determine whether the construction can proceed normally. In actual engineering practice, slump is often measured through manual experiments, which makes it difficult to meet the requirements of measurement accuracy and real-time performance. This makes how to realize online detection of slump a technical problem that needs to be solved urgently.

In order to solve the above technical problems, the invention patent CN202210799909.2 "A method for online detection of concrete slump" detects and analyzes the corresponding relationship between concrete slump and concrete batching ratio, working current of concrete mixer, vibration frequency and mixing time, and realizes online detection of slump in the concrete production process. However, it is not difficult to find out through analysis that there are the following technical problems:

Due to the quality of engineering materials, such as deviations in sand particle size and moisture content, there will inevitably be certain deviations in the setting of the concrete mix ratio of engineering materials. For concrete using the same concrete mix ratio, there is often a certain correlation between the working current and vibration frequency of the concrete mixing host as the mixing time changes. Therefore, if the above correlation is not considered, it may lead to the accuracy of the concrete slump test results being difficult to meet the requirements when there is an error in the concrete mix ratio.

In view of the above technical problems, the present invention provides a concrete online detection method and system.
