Lithium nitrate 30% solution is widely valued in the construction industry for its role as a concrete admixture, specifically to mitigate alkali-silica reaction (ASR).
ASR is a chemical reaction that occurs between the alkaline components in cement and reactive silica found in some aggregates, leading to the formation of an expansive gel that can crack and weaken concrete over time. By introducing lithium nitrate solution into the concrete mix, the formation of this damaging gel is significantly reduced, thereby enhancing the durability, stability, and service life of concrete structures such as bridges, highways, and buildings.
In addition to its use in construction, lithium nitrate 30% solution is also employed as a corrosion inhibitor in industrial absorption chillers and heat transfer systems. These systems often contain metal components that are susceptible to corrosion, especially when exposed to water or other working fluids. The addition of lithium nitrate helps form a protective layer on metal surfaces, reducing the risk of corrosion and extending the operational life of the equipment. This makes lithium nitrate solution a valuable additive in maintaining the efficiency and reliability of large-scale cooling and heating systems in commercial and industrial settings.
