Three dimensional acoustic emission technique is applied to observe the phase of the fracture process zone of concrete which is created ahead of the crack tip and significantly influences the tension softening behaviour of concrete. The results show that the fracture process zone is already created
The material under investigation was ordinary concrete of B 20 class, different in the sizes of coarse aggregate and water-cement ratio of the same value w/c = 0.55. It was found during the tests that there were two kinds of sample cracking mechanisms. Some samples cracked at the moment of the initi
