The purpose of this study was to recycle red mud, an industrial byproduct that generates 300,000 tons per year, into the construction industry. Red mud was prepared as a liquid, neutralized with sulfuric acid, and replaced with cement mortar. The properties of liquefied red mud (LRM) neutralized with sulfuric acid (LRM + S) were investigated …
II. GENERAL FEATURES OF SULFURIC ACID ATTACK Sulfuric acid [H2 (SO4)] attack on concrete may be characterized by a chemical reaction between the acidic media and cement hydration products and, if soluble, the aggregate particles, results in excessive formation of gypsum (Fig. 2.1). The nature of attack of sulfuric acid on concrete is …

When concrete is attacked by sulfuric acid, there are two important aspects. On the one hand, there is the reaction with the sulfate ion; on the other hand, the action of the hydrogen ion has to be considered. It can be stated that sulfate attack comprises only one aspect of sulfuric acid attack (Monteny et al. 2000). The sulfuric acid first ...
