Customer Case Study: Lithium Carbonate Application in Southeast Asia’s Construction Sector
A leading construction company in Malaysia, specializing in infrastructure projects, faced stringent requirements for concrete durability due to Southeast Asia’s hot, humid climate and local aggregate properties.
Challenge
The client identified a risk of alkali-silica reaction (ASR) in aggregates, which could cause concrete cracking and compromise structural stability. An effective alkali silica reaction inhibitor concrete solution was required — one that could be precisely dosed and integrated into the existing mix design without disrupting structural performance targets.Traditional solutions fell short of meeting sustainability needs.
Solution
The client partnered with EASTCHEM, a professional chemical materials supplier.As a dedicated lithium carbonate construction chemical supplier, EASTCHEM provides high-purity Li₂CO₃ with full COA documentation, consistent batch quality, and responsive technical support across Southeast Asia.to incorporate Lithium Carbonate as a concrete admixture to effectively suppress ASR.
As a proven Lithium Carbonate ASR inhibitor, it chemically suppresses the expansive reaction between alkali ions and reactive silica aggregates — the primary cause of long-term concrete cracking in tropical infrastructure.
Implementation
Our technical team analyzed the client’s needs, optimized the concrete mix design to maximize Lithium Carbonate’s effectiveness, and provided expert guidance.
| Parameter | Specification |
|---|---|
| Chemical Name | Lithium Carbonate |
| CAS Number | 554-13-2 |
| Appearance | White crystalline powder |
| Purity | ≥99.0% |
| Recommended Dosage | 0.05–0.30% by weight of cement |
| ASR Expansion Reduction | ≥80% vs untreated reference |
| pH (1% solution) | 10.0–11.5 |
| Shelf Life | 24 months (dry, sealed storage) |
Results
Technical Outcome: Lithium Carbonate reduced concrete expansion to 0.04%, well below the ASR risk threshold.
This result directly demonstrates the lithium carbonate concrete durability improvement achievable through precise dosage optimization and professional mix design support.
Project Outcome: Structural durability met international standards.
Economic and Environmental Benefits
Initial costs rose by approximately 5%, but the extended lifespan minimized long-term maintenance expenses while reducing resource waste, supporting green construction goals.
