Lithium Carbonate as an Additive in Concrete and Cement

Lithium carbonate (Li₂CO₃) serves as a valuable additive in concrete and cement, offering significant improvements to material performance.

1. Suppression of Alkali-Silica Reaction

Lithium carbonate effectively reduces alkali-silica reaction (ASR) in concrete, decreasing expansion and cracking, and enhancing durability.

2. Enhanced Permeability and Freeze Resistance

It improves the permeability of concrete by reducing the infiltration of water and salts, and increases freeze resistance in cold climates.

3. Accelerated Cement Hydration

Lithium carbonate also speeds up the hydration process of cement, resulting in increased early strength and faster construction progress.

4. Improved Durability

It helps lower the alkalinity of cement, reducing the impact of corrosive substances and extending its lifespan.

In summary, lithium carbonate's role as an additive in concrete and cement enhances material performance, prolongs lifespan, and reduces maintenance costs, providing essential support for modern construction projects.
