칼루마이트 및 VA/E/MMA 분말수지 병용 PMM의 자기방청기능 규명을 위한 기초적 연구

A Basic Study on the Self-Corrosion Inhibition Function Identification of VA/E/MMA-Modified Mortar with Nitrite-Type Hydrocalumite

The purpose of this study is to investigate chloride ion adsoption property of cement mortar using nitrite type hydrocalumite(calumite) with self-corrosion inhibition function. Superior corrosion inhibition function of the VA/E/MMA-modified mortars with calumite was ascertained from accelerated corrosion test in the previous study. In this study, VA/E/MMA-modified mortars with calumite were prepared with calumite contents of 0, 5, 10% and polymer-binder ratio of 0, 10%, and tested for chloride ion adsorption to make it clear how calumite gives self-corrosion inhibition function to cement mortar. As a result, chloride ion adsorption property of VA/E/MMA-modified mortars with calumite was improved by increasing calumite contents compared to unmodified mortar regardless of using VA/E/MMA terpolymer powder or not.
