Nuclear magnetic resonance (NMR) tests were conducted to investigate the effect of permeable crystalline materials on the microstructure and internal void distribution of recycled aggregates (RA) and recycled aggregate concrete (RAC). The following test procedures were conducted: (1) Standard cube specimens were prepared and cured for 28 days, after which 3 cylindrical specimens measuring 25 mm in diameter and 40 mm in height were cut from each cube for testing. (2) The specimens were then vacuum-saturated for 24 h to ensure complete saturation. (3) The pore size distribution and porosity of the saturated specimens were analyzed using a Newman core analyzer.
