Crack Width Estimation of Mortar Specimen Using Gas Diffusion Experiment
Maintenance of structures using self-healing concrete technologies has recently been actively studied. However, unlike the technological development of self-healing concrete, research focused on evaluating the self-healing performance is insufficient. Although water permeability experiments are wide...
