The most widely used building materials in the world are those based on Portland cement. Unfortunately, their use is associated with a number of negative environmental impacts, from CO2 emissions to the depletion of natural aggregate resources. In order to contribute to greater environmental responsibility, this work investigated building materials containing both alternative binders and fillers. Magnesium oxychloride cement (MOC) is considered to be a more sustainable binder than Portland cement and is characteri...

Non-destructive testing (NDT) of 3D-printed concrete is challenging due to complex geometries and layer-dependent material heterogeneity. Photogrammetry captures surface geometry, but its outputs cannot be directly linked to NDT values. This study presents a workflow that integrates photogrammetric models with rebound hammer measurements and applies radial basis function (RBF) interpolation to visualize near-surface strength. Each measurement point is matched to its 3D coordinates on the mesh, enabling consistent ...
