Comparison of Calcium Chloride Types
| Type | Description | Properties | Intended Applications |
|---|---|---|---|
| Anhydrous Calcium Chloride | Pure, crystalline form, typically sold in solid form. | High reactivity, accelerates hydration, enhances early strength gain. | Projects requiring rapid strength development, especially in cold weather conditions. Suitable for precast concrete elements and high-volume concrete pours. |
| Hydrated Calcium Chloride | Contains water molecules, often available as a solution. | Lower reactivity compared to anhydrous, suitable for applications needing less aggressive curing. | Projects where a moderate curing acceleration is desired, particularly in situations with moderate temperatures. Can be cost-effective in some situations. |
Specific Uses and Suitability, Where to buy calcium chloride for concrete
The choice between anhydrous and hydrated calcium chloride depends on the project’s specific requirements. Anhydrous calcium chloride is ideal for applications demanding rapid strength gain, like precast concrete or when working in freezing conditions.
