Lithium Silicate for Concrete Densification and Surface Hardening

In modern construction, concrete durability and surface performance have become critical evaluation standards. Traditional concrete surfaces often suffer from dusting, abrasion, cracking, and chemical attack over time.

To address these issues, Lithium Silicate has emerged as a high-performance solution for concrete densification and surface hardening.

Compared with sodium silicate and potassium silicate, Lithium Silicate Densifier provides superior penetration, long-term durability, and minimal surface residue.

What Is Lithium Silicate?

Lithium Silicate is a water-based inorganic solution designed to react with free calcium hydroxide (Ca(OH)₂) in concrete.

When applied to concrete surfaces, it penetrates deeply and chemically reacts to form additional calcium silicate hydrate (C-S-H) gel.

This reaction:

• Densifies the concrete matrix

• Reduces porosity

• Increases surface hardness

• Improves abrasion resistance

Unlike traditional silicates, Lithium Silicate does not create excessive alkali residue, reducing the risk of efflorescence and surface whitening.

How Lithium Silicate Works in Concrete

Concrete naturally contains free lime after hydration. This free lime contributes to dusting and weak surface structure.

When Lithium Silicate Solution is applied:

1. It penetrates the concrete surface.

2. It reacts with calcium hydroxide.

3. It forms additional C-S-H gel.

4. The pore structure becomes denser.

The result is a harder, stronger, and more durable concrete surface.

Advantages of Lithium Silicate Over Traditional Silicates

1. Better Penetration

Lithium ions are smaller than sodium or potassium ions.
This allows Lithium Silicate to penetrate deeper into concrete surfaces.

2. Reduced Efflorescence Risk

Unlike sodium silicate, Lithium Silicate reduces alkali-related surface whitening.

3. Faster Reaction Time

Lithium Silicate Densifier reacts efficiently without leaving heavy residues.

4. Long-Term Durability

The densified surface resists:

• Abrasion

• Dusting

• Oil penetration

• Chemical attack

Applications of Lithium Silicate

Lithium Silicate for Concrete Floor Treatment is widely used in:

• Industrial warehouses

• Logistics centers

• Parking garages

• Manufacturing plants

• Shopping malls

• Airport terminals

It is also suitable for:

• Polished concrete systems

• Concrete floor renovation

• Dust-proof floor upgrades

Performance Benefits

Using Lithium Silicate Concrete Densifier provides:

• Increased surface hardness

• Improved abrasion resistance

• Reduced dust generation

• Enhanced gloss in polished floors

• Lower maintenance cost

• Extended service life

For large industrial projects, this significantly reduces lifecycle cost.

Lithium Silicate vs Sodium Silicate vs Potassium Silicate

Because of these advantages, Lithium Silicate has become the preferred solution in high-end concrete floor treatment systems.
