Porous concrete is an environmentally friendly material. To evaluate the damage and
discuss the failure mechanism of porous concrete, a uniaxial compression test was carried …

Acoustic emission (AE) has been widely used in concrete research as a dynamic
nondestructive test method. In this study, the AE characteristics of concrete with different …

To study the effect of loading rate on the fracture behavior, three-point bending fracture tests
of concrete with loading rates of 0.0001 mm/s, 0.001 mm/s, 0.01 mm/s and 0.1 mm/s were …

As an important component of concrete, aggregate has a significantly influence the fracture
behavior of high performance concrete. In this paper, the effects of aggregate size …

This study aims to investigate the crack growth behavior of plain and fly ash concretes with
different curing periods during uniaxial compression testing using acoustic emission (AE) …

The results of acoustic absorption modeling of porous concrete considering the gradation
and shape of aggregates and void ratio are presented. To model the void texture of porous …

Acoustic emission (AE) acquiring technique was employed to explore the concrete fracture
procedure in this study. Several parameters were evaluated through three-point bending …

In this research, acoustic emission (AE) characteristics of three-point-bending concrete
beams were investigated during the entire loading period. It was found that the relative notch …

The acoustic emission (AE) signals from mortar, concrete and steel fiber reinforced concrete
beams during the entire fracture process were recorded and analyzed. Different filters were …

Understanding the properties of concrete under load is essential for assessing the stability
and serviceability of buildings. In this work, the uniaxial compression test of concrete was …
