摘要：

The present work presents a means of evaluating the particle size distribution of aggregates on hardened concretes via an image processing based technique. Such a technique may be employed to the reconstitution of hardened concrete composition, which is a matter of interest concerning, specially, lightweight aggregate concretes. This work presents the results obtained by applying the proposed methodology to synthetic experiments and to pictures taken from lightweight aggregate concrete samples. (C) 2011 Elsevier Ltd.
