In this study, it was evaluated the permeability of cold joint concrete, to evaluated the permeability considering slag concrete and OPC. In addition, the water permeability was evaluated by comparing the sound and cold joint concrete. As a result, OPC-Joint(3.76×10-10m/s), Slag-Joint(3.36×10-10m/s), OPC(2.65×10-10m/s), Slag(2.36×10-10m/s) was evaluated in this order. The OPC-joint is the most highly evaluated. This is estimated to be because the density of the pore structure.
