초록

In this paper, liquid red mud and sulfuric acid neutralized liquid red mud were manufactured to recycle red mud sludge, a by-product of the aluminum manufacturing process, and applied to slag cement mortar to examine the possibility of its use as a building material. Liquid red mud and sulfuric acid neutralization As a result of replacing liquid red mud with slag cement mortar, it was found to have a positive effect by shortening the initial setting time and improving initial strength. In particular, when sulfuric acid is added to red mud, it reacts with NaOH to produce a compound in the form of Na2(SO4)3, which acts as a factor in reducing the rapid setting phenomenon of slag cement mortar added with sulfuric acid-neutralized liquid red mud, reducing the 28-day strength. The results showed higher strength than slag cement mortar added with liquid red mud. In the XRD analysis results, Xonotlite and Gismondite were identified as the new A peak and Gismondite as the B peak, which appeared to affect the initial compressive strength results. Therefore, it is believed that sulfuric acid neutralization liquid red mud using red mud sludge has high utility in the construction industry.
