Method for calculating the porosity of cement composite materials using X-ray computed tomography

Abstract

X-ray computed tomography is a promising method for non-destructive testing of the internal structure of materials. The article provides an overview of the use of computed tomography to study the structure of cement-based composite building materials. Computed tomography of four samples of fine-grained concrete mixture was performed: basic composition and compositions with different contents of additives of redispersible polymer powder and calcium formate. A method for calculating the porosity in these samples using a constructed 3D model and special software is presented.
