HIGH-SPEED PHOTOGRAPHY FOR FRACTURE STUDIES OF CONCRETE

The fracture of ordinary and polymer-impregnated concrete has been studied by high-speed photography. 20-40 mm thick concrete prisms were subjected to a dynamic loading by detonation of a high explosive in contact with the top surface of the specimen. A multiple Kerr-cell camera was used for recording the fracture. A description of the Kerr-cell and the equipment used is given, and some typical fractograms taken at different intervals are shown. An estimation of the stresses transmitted showed that under dynamic loading the polymer-impregnated concrete did not show any significant increase in strength above the static strength. /Author/
