Abstract: “the concrete quality evaluation is defined by the statistical processing of the resistance values obtained from the rupture test specimen (potential strength), or samples (real strength). In certain occasions, when the methods above mentioned are not possible or in order to get extra information, mainly on-site, it is common to use nondestructive testing (NDT). Lately, taking advantage of photography cameras and the growing capacity and processing speed of computers, strength evaluation and concrete deformation measuring procedures have been developed based on no-contact techniques consisting of images record, their subsequent digital processing and their treatment through algorithms of computing engineering. This paper s suggests developing, based on new techniques, a classification model of conventional concrete based exclusively on the shooting of images and the subsequent proceeding of the characteristics deduced from their digitalization. The images come from tests and/or witnesse”
