Description

<p>In this study, with the assumption that the amount of air in concrete reduces due to the construction processes, the effects on freeze-thaw resistance and scaling resistance when solid paraffin emulsion was mixed in concrete was investigated. From the experimental tests it was observed that, when solid paraffin emulsion was mixed, the freeze-thaw resistance and scaling resistance under the chloride ion supply environment improved. In addition, it was confirmed that the measurement results of the chloride ion concentration after the scaling test varied depending on the conditions of the freeze-thaw cycle.</p>
