Type IL cement exhibits improved resistance to chemical attacks compared to traditional Portland cement

Type IL cement exhibits improved resistance to chemical attacks compared to traditional Portland cement (Type I), primarily due to its composition and the incorporation of additional materials that enhance its durability in aggressive environments. The increased limestone content in Type IL cement contributes to a denser microstructure, reducing permeability and enhancing resistance to chemical ingress. For example, a study on hybrid alkali-activated cements demonstrated that reducing the basicity level and incorporating technogenic alumina silicates increased the material’s acid resistance, showing a corrosion resistance coefficient of up to 0.88 (Kovalchuk & Zozulynets, 2022). Additionally, research on the use of granulated blast-furnace slag in concrete revealed that it significantly improved acid resistance, with specimens showing reduced damage and lower weight loss after exposure to sulfuric acid compared to conventional binder compositions (Acta Polytechnica CTU Proceedings, 2022). Furthermore, studies have indicated that substituting portions of Portland cement with slag and other supplementary cementitious materials (SCMs) enhances resistance to sulfate attacks, as evidenced by reduced expansion and deterioration in mortar exposed to sulfate solutions (Yu et al., 2023). These characteristics make Type IL cement more suitable for use in harsh environments where chemical durability is crucial.
