Shape parameters of recycled aggregate and determination its area of mortar and aggregate using imaging techniques

Author(s): Chiranjib Roy, Md. Shariful Islam, Firoz Ahamed
Abstract: In this study, relationships between aggregate shape parameters and volume of recycle mortar and aggregate were investigated using digital image processing and analysis methods. The study was conducted based on two parameters, aggregate type and maximum aggregate size, at two levels. A total of 3 cylinder recycled concrete specimens were prepared at a constant water-cement ratio. After the tests were performed, each specimen was cut into 4 equal pieces in order to obtain the digital images of cross sections using a digital image analysis. A number of aggregate shape parameters were then determined from the digital image of the cross sections to investigate their relationships with the recycled mortar and aggregate. The results indicated that even though the aggregate type was found to give strong correlation with the compressive strength. The study suggested that the analyses of relationships should be further investigated by including the effects of aggregate distribution within the specimen cross sections.
