Abstract:

The objective of this project was to evaluate current technologies that have the capability of characterizing the air void system in concrete within the first several hours of placement. This objective was met by developing a comprehensive technology assessment and literature review, and conducting a laboratory evaluation of two selected technologies: ultrasound and thermography. The literature review presents a comprehensive assessment of research developments in the area of material characterization and structural health monitoring, focusing on technologies that are currently used to characterize air voids in concrete and those that have the capability of characterizing the air void system in concrete within the first 24 hours of placement. Special focus was placed on determining which technologies and equipment development may have a strong potential of being implemented in the field. The laboratory evaluation of the two selected technologies describes results obtained from experiments aimed at demonstrating the feasibility of ultrasound and thermography technologies in characterizing the air void system of fresh concrete, with an eye toward field implementation. Experimental results showed that both technologies can capture physical features that are significantly affected by the air void system in concrete.
