Holographic interferometry for the determination of fracture process zone in concrete

Holographic interferometry is used to determine the fracture process zone of mortar and concrete. The tests reveal the presence of a significant fracture process zone prior to peak load of the specimen. The fracture process zone can be subdivided into an elliptical, continuous region and a narrow bu...

Summary:Holographic interferometry is used to determine the fracture process zone of mortar and concrete. The tests reveal the presence of a significant fracture process zone prior to peak load of the specimen. The fracture process zone can be subdivided into an elliptical, continuous region and a narrow but long, disrupted band along which load is transferred due to aggregate interlock. The larger the aggregates, the more pronounced is this fracture process zone.
