Influence of Aeration of Concrete on Acoustic Emission and Fracture Mechanical Parameters Obtained from Three-point Bending Tests

Popis výsledku v původním jazyce

This paper examines the analysis of acoustic emission signals captured during three-point bending fracture tests of concrete specimens with similar water-cement ratio, but one set of specimens was prepared from aerated concrete. The acoustic emission method is an experimental tool well suited for monitoring fracture processes in material. The typical parameters of acoustic emission signals were identified from the acoustic emission records for two different concrete mixtures to further describe the under-the-stress behaviour and failure development. An understanding of microstructure-performance relationships is the key to true understanding of material behaviour. The crack growth was continuously monitored using four acoustic emission sensors mountedon the specimen. The acoustic emission results are accompanied by selected fracture mechanical parameters determined via evaluation of load versus displacement diagrams recorded during three-point bending fracture tests.
