2D-fractal based logics and computing architecture for the characterization of concrete fine and ultrafine particles
An innovative method based on 2D Fractal analysis is proposed to detect and to quantify the overall attributes of fines and ultra-fine particles. The developed set of procedures allows to perform the study of fine particles topological assessment on a flat surface, evaluating fines population structure and texture by computing statistical fractal parameters. The results obtained with this innovative approach have been linked to those classical morphological, morphometrical and rheological analysis in order to develop and implement a reliable and simple tool to use for particulate products characterization and recognition in order to correlate the characteristics of fine particles detected by the proposed logics and those usually extracted by using classic method (e.g. flowability, attrition, size class distribution, surface characteristic, etc.). The developed procedure can thus be utilized as an innovative experimental methodology to analyze the micro-structural characteristics of concrete, responsible for many peculiar features of the fracture phenomenon. Following this approach, it could be possible to study the depth and the shape of the pores in order to confirm the lacunar fractal character of the stress section. Further studies will be addressed to develop: i) on-line control strategies applied to fine particles production and control, ii) off-line procedures addressed to detect and quantify cement and concrete composite microstructure according to fine additives utilized and iii) to establish correlations between fine products characteristics and resulting re-inforced fines based cement-concrete constructions.
