Code and data for optical microstructure analysis of concrete with recycled polymer shot (porosity–fractal–texture)

This Zenodo record provides the full author-generated Python code and underlying dataset used for quantitative optical microstructure analysis reported in the manuscript "Recycled Polymer Shot as Sustainable Additive for Concrete: Insight into Microstructure and Key Performance Metrics". The package includes raw optical micrographs, scripts for segmentation and feature extraction, dependency specifications, and the resulting CSV output tables (porosity, fractal and texture descriptors) to facilitate reproducibility and reuse.
