The purpose of this study is to grasp the change in mechanical behavior of meso-scale mortar specimens damaged by Ca leaching. Particularly, thin mortar specimens were immersed in demineralized water and NaCl solution for 0, 56, 112 and 168 days. After immersion tests, three points bending tests and double direct shear tests were carried out in order to determine elastic modulus, tensile strength, fracture energy and tensile softening curve from load displacement curves using back analysis and shear strength. In addition, chemical analysis was conducted so as to clarify how amount of calcium hydroxide and C-S-H and in the porosity quantitatively. Consequently, it was found that the change in mechanical behavior was strongly related to the change in the amount of cement hydrate and porosity. Furthermore, mechanical models that can consider the change in porosity were constructed and were evaluated adequacy itself.
