Usage of 3-D Based Methods for the Detection of Aggregate Microtexture

Abstract

Some of the available advanced three-dimensional based methods for measurement of microtexture have been described. These methods are generally divided into three categories, namely image analysis based methods, laser based methods and photogrammetry methods. Moreover, a particle of aggregate can be captured using a stereomicroscope and using the appropriate software to obtain a 3-D image of investigated aggregate. Software also includes an interactive measurement tool that allows to obtain a profile of aggregate particle. The stereomicroscope method is also presented in the paper. The usage of the microscope for the detection of aggregate microtexture allows to eliminate some of the disadvantages of described methods and provides additional opportunities for microtexture evaluation.
