Development of a general model of aggregate rebound for dry-mix shotcrete—(Part II)
Abstract A mechanical model previously developed is briefly described and linked to particle velocity versus size relationships experimentally obtained, allowing prediction of the energy of rebound of an aggregate particle during shooting. In addition, a failure criterion, based on the work necessary to debond a particle, is introduced in order to allow calculating the probability of rebound. The model shows good agreement with the experimental data in terms of predicting not only the overall rate of rebound but also its composition. This model provides a novel insight into the mechanisms involved in dry-mix shotcrete aggregate rebound and offers rational explanations to its dependence on aggregate size, cement content, shooting consistency and presence of silica fume.
