Research Abstract

The elastic waves propagating in concrete material are interfered with each other and reflected by aggregates and then the observed waves become much complicated but must have the information of aggregates or other influential factors. Thus in this study chaotic theory is applied to evaluate the complicity of the waves transmitted throughout concrete material. As a result it is found that prediction error of the received signal has some correlation with the homogeneity of the material, and that correlation dimension and maximum Lyapunov exponent have strong correlation with the bond matrix around the aggregates.
