In this study, relationships between aggregate shape parameters and compressive
strength of concrete were investigated using digital image processing and analysis
methods. The study was conducted based on three mix design parameters, gradation
type, aggregate type and maximum aggregate size, at two levels. A total of 40 cubic
concrete specimens were prepared at a constant water-cement ratio. After the
compressive strength tests were performed, each specimen was cut into 4 equal
pieces in order to obtain the digital images of cross sections using a digital flatbed
scanner. A number of aggregate shape parameters were then determined from the
digital image of the cross sections to investigate their relationships with the
compressive strength. The results indicted that even though the aggregate type was
found to give strong correlation with the compressive strength, weak correlations,
however, exist between the compressive strength and the aggregate shape
parameters. The study suggested that the analyses of relationships should be further
investigated by including the effects of aggregate distribution within the specimen cross sections.
