Lithium Salt Coagulant

Lithium Salt Coagulant

 

Lithium salts, particularly lithium carbonate is known for their ability to act as set accelerators in cement-based products. They help to speed up the setting time, improve early strength development, and enhance certain properties of the final hardened material.

Items CL-99P

Solubility Slightly soluble in water, almost insoluble in alcohol, aqueous solution is neutral.

Uses of Lithium Salts in Cement-Based Products:

  • Set acceleration: Reducing the initial setting time, which is especially useful in cold weather or thin-mix applications.
  • Early strength gain: Promoting faster development of early strength, useful in repair or fast-track construction.
  • Improved workability: Sometimes they help in improving the flow and handling of the mortar or concrete.

Application in Floor Mortar:

  • Lithium salts can be added in small amounts to floor mortars to accelerate setting and curing times.
  • They can also influence the microstructure by promoting denser and more durable cement matrices.
  • Proper dosage is critical to avoid overstimulation, which can cause rapid setting or cracking.

Important Considerations:

  • Compatibility with other admixtures (like superplasticizers or foam reducers).
  • Correct dosage based on the specific formulation.
  • Cost and availability considerations, as lithium compounds tend to be more expensive than other accelerators.
