Aggregate-cement paste interface. II. Influence of aggregate physical properties
This paper describes part of a large project on aggregate-cement interactions and interface bonding mechanisms in concrete. This part of the study investigates the influence of aggregate physical properties on the nature of aggregate-cement paste interfacial bonding with the aim of establishing the bonding mechanisms as controlled by aggregate physical properties. A newly developed experimental technique to characterise quantitatively the aggregate surface texture using a surface profilometer is also presented. Three commonly used concrete aggregate rocks (basalt, limestone, and quartzite) were investigated. Significant differences in the measured bond strength and modes of failure of rock-hardened cement paste composite specimens under uniaxial tension were observed between the different rock types. Based on the results presented, it is apparent that for a given cement paste, the interfacial bond strength cannot be predicted from aggregate surface roughness alone.
