3 Terms and Definitions

This document does not have terms and definitions that need to be defined.

4 Summary of method

The cement mortar test body formed according to the fixed lime-sand ratio and water-cement ratio and cured for 28 days was left to stand under the negative pressure condition of vacuum saturated salt equipment for a period of time. After a certain time, soak in a certain concentration of sodium chloride (NaCl) solution for 18 hours. After drying the specimen, the conductivity of the specimen was detected, based on The chloride ion diffusion coefficient of cement mortar was calculated by Nernst-Einstein equation.
