- Abstract
- A non-destructive method of evaluation of volumetric strain due to microcracking was used to characterise microcracking in concrete prisms under uniaxial compression. Chloride profiles were also measured after the same concretes were exposed to chloride environment. The relationship among microcracking, stress level and chloride penetration of concrete was analysed based on the experimental results. Under compressive load the apparent chloride diffusion coefficient decreases until about one third of the ultimate load. Further increase of compressive load increases the chloride diffusion coefficient again. There is a close link between microcracking and stress level. The index of volumetric strain due to microcracking can be used to indicate the microcracking and study chloride transport into concrete under the influence of microcracking.
