Lithium Carbonate Enhancing Cement Performance in Hot-Climate Construction
In a major North African urban development project, the contractor faced a challenge common across the region: high-temperature environments causing rapid setting, reduced cement hydration stability, and inconsistent final strength. As construction accelerated, local materials struggled to meet the performance requirements for modern high-density buildings.
The contractor sought a solution capable of improving cement hydration control while keeping overall project cost within budget. After preliminary discussions, they chose to evaluate our Lithium Carbonate + construction materials solution for use in cement modification and high-performance dry-mix formulations.
1. Customer Pain Points Before Using Lithium Carbonate
Rapid setting under high temperatures
Daytime temperatures exceeding 35°C caused cement to set faster than expected, making surface finishing difficult and increasing rework.
Weak control over cement hydration
Existing accelerators lacked stability in extreme climates, resulting in variable strength development between different batches.
Limited availability of high-performance additives
Local suppliers mainly provided traditional additives that did not meet the technical specifications required for high-rise projects.
Need for a cost-effective, long-term solution
The project required a material that could enhance performance without significantly increasing costs.
2. Our Solution: Lithium Carbonate + cement accelerator system
Based on the materials used in the project, we recommended a formulation integrating high-purity Lithium Carbonate + cement accelerator additives, customized for hot-climate cement applications.
Improved early-stage hydration
Lithium Carbonate promotes controlled acceleration of cement hydration, ensuring:
Stronger early strength
Reduced variability
Better compatibility with local cement types
Enhanced performance in hot environments
Even under high temperatures, Lithium Carbonate maintained stable hydration kinetics, preventing early-setting issues.
Lower overall usage compared with conventional accelerators
Because of its higher efficiency, the contractor required a significantly lower dosage, reducing material consumption.
Technical guidance provided
We supported the customer with:
Dosage recommendations
Temperature–strength correlation charts
Mixing procedures for dry-mix mortar
Onsite troubleshooting guidance
This combination of Lithium Carbonate + technical support allowed the customer to integrate the additive smoothly into their existing workflows.
3. Field Test Performance
After two months of continuous application, the project recorded the following improvements:
Consistent early strength development
7-day and 14-day strength data stabilized, reducing batch-to-batch deviation by nearly 30%.
Improved workability under heat
Concrete remained workable for longer periods, reducing labor stress and rework rates.
Faster construction progress
The acceleration effect allowed earlier formwork removal, helping the project maintain a tight schedule.
Cost reduction at the project scale
Although Lithium Carbonate is a high-value additive, its lower dosage and high efficiency decreased the overall cost of accelerators used on site.
4. Long-Term Benefits
The contractor noted several long-term improvements:
More predictable cement behavior in summer months
Reduced material waste
Better surface finishing quality
Stronger confidence in adopting higher-performance building materials
They have since expanded procurement to include other products such as RDP, PCE, and HPMC, strengthening the partnership.
