Abstract

In this study, the specimens of cement clinker minerals such as 80C3-S-15C4AF-5C3A added various blending materials were immersed in artificial seawater. In order to ascertain the effect of SO3 and blending materials on seawater resistance of the specimens, the acceleration experiment in the artificial seawater was carried out by repeating of immersion and drying operation periodically. As inner part of the specimen immersed in artificial seawater, Friedel's salt was produced by reaction with Cl ion. In outer part of the specimen, gypsum and ettringite were mainly formed. With the increase of SO3 content in the specimen the formation of ettringite was increased and Frieldel's salt in inner part was decreased. Total pore volume of the specimens was increased according to the amount of Cl ion penetrated and Mg(OH)2 leached in the solution.
