Assessment of Internal Structure of Spun Concrete Using Image Analysis and Physicochemical Methods

Area of Science:

• Materials Science
• Civil Engineering
• Concrete Technology

Background:

• Spun concrete poles require internal structure assessment for quality control.
• Traditional physical and chemical methods can be time-consuming and destructive.
• Non-destructive imaging techniques offer potential for efficient evaluation.

Purpose of the Study:

• To evaluate the efficacy of X-ray microcomputed tomography (µCT) and 2D optical scanning for assessing the internal structure of spun concrete.
• To compare imaging results with traditional laboratory verification methods.
• To demonstrate the potential of optical scanning for quality control in spun concrete production.

Main Methods:

• X-ray microcomputed tomography (µCT) imaging.
• Two-dimensional optical scanning.
• Physical and chemical laboratory analysis for validation.
• Image analysis of concrete cross-sections.

Main Results:

• Optical scanning, coupled with image analysis, proved effective for evaluating the internal structure of spun concrete.
• Imaging methods can complement traditional laboratory techniques.
• Porosity analysis via imaging can identify issues with spinning parameters (speed, time).
• Cement content distribution analysis indicates compliance with corrosion durability requirements.

Conclusions:

• Optical scanning is a viable, non-destructive method for assessing spun concrete quality.
• This methodology can optimize spun concrete production processes.
• The approach serves as an effective tool for verifying concrete structure and ensuring durability.
