X-Ray Microtomography System Applied in Characterization of Lightweight Concrete Structures

Microtomography is a powerful non-destructive method that allows the visualization of the internal structure of the object and makes possible to generate trust internal graphic models of the object. Concrete is a mixture widely used in the construction industry due to the union between its mechanical properties with the low cost for its production. The application of X-ray microtomography in lightweight concrete structures allows the visualization of the layout and formation of existing internal structures in it. It was possible to identify the presence of ethyl vinyl acetate (EVA) and piacava fibers in the internal structure of the samples and to classify the high density aggregates according to the ASTM C125-18 standard.
