Abstract

Abstract : This research concerns anti-seawater corrosion performance of slag composite cementitious material (SM agent)-cured coastal saline soil in one year. Based on compressive strength, scanning electron microscopy, electron-dispersive spectrometry and X-ray diffraction analysis, this paper presents studies on the anti-seawater corrosion performance, micro-structure and hydration products of the shell of SM agent-cured saline soil in seawater curing. The test results show that SM agent-cured coastal saline soil in seawater generates compact hard calcium carbonate (CaCO3 ) shell, which not only prevents seawater erosion, but also prevents the calcium hydroxide (Ca(OH)2 ) to dissolve erosion, which is the fundamental reason why SM agent has a good anti-seawater corrosion performance.
