Acoustic Emission for Monitoring the Elastic Concrete Beam Subjected to Three-point-bending Tests

Abstract

The application of the acoustic emission (A processes and crack characterization in elastic c paper. Thirty-six elastic concrete three-point I technique. Four different rubber contents, O% consideration. Test results show that the AE ene significantly with the increasing rubber content. contents, the number gaps between two com occurrence means that more rubber particles m For high content of rubber particles, the top of t the load-time curve for low content. Two or mo AE energy curves. This phenomenon corresp particles can help concrete disperse into two ductility. The present experimental study measurement of fracture energy and the relatio energy of elastic concrete. An equation has been elastic concrete by knowing acoustic emission
