| | Effect of the Interfacial Transition Zone on the Conductivity of Portland Cement Mortars - Discussion |
 | | Second, since there is a lower amount of cement and greater amount of water in the ITZ and because the total amount of water and cement in the mortar is conserved, there must be a higher amount of cement and a lower amount of water in the matrix. |
 | | First, the ITZ forms around the aggregate particles, increasing the local conductivity in the ITZ because of the higher porosity, which tends to increase the overall mortar conductivity. |
 | | ≈ 6 was necessary for the increased conductivity of the ITZ to overcome the decreased conductivity due to the insulating aggregate particles. |
