Abstract

The purpose of the present study was to determine the change in tensile behavior of a meso-scalc mortar specimen immersed in a solution of NaCl. In particular, mortar specimcns were immersed in a NaCl solution for 2 months, and then three-point bending tests and chemical analyses were conducted to determine the influence of the cement hydrate (CH and CSH) concentration on the tension-softening behavior of the material. To this end, tension- softening curves were obtained from load-displacement curves via a back analysis. Wc found that tensile strength and fracture energy were reduced as the concentration of CH decreased. Furthermore, the tensile-softening model for the deteriorated mortar was proposed.
