Physico-Chemical Properties of Lithium Silicates Related to Their Utilization for Concrete Densifiers.

Protection of concrete against aggressive influences from the surrounding environment becomes an important step to increase its durability. Today, alkali silicate solutions are advantageously used as pore-blocking treatments that increase the hardness and impermeability of the concrete's surface layer. Among these chemical substances, known as concrete densifiers, lithium silicate solutions are growing in popularity.

Effect of Alkali Salts on the Hydration Process of Belite Clinker.

Belite-rich cement is a low carbon footprint binder. However, its use is accompanied by a low initial rate of hydration. This can be partially eliminated by grinding to a high specific surface or through the addition of admixtures (mineralizators or activators).
