Product Description

Description:
Added to cement mixes, sodium sulfate accelerates C3A hydration, reducing setting time and improving early strength (especially in cold weather).

 

Key Benefits:
1. Cost-Effective Alternative - Cheaper than calcium chloride (non-corrosive to rebar).
2. Compatible with Admixtures - Works with PCE superplasticizers.
 

Recommended Dosage:

• General Use: 0.5-2% of cement weight.

• Cold Weather Concreting: 1-3% (monitor setting time).

Note: Excessive use may cause efflorescence - limit to 3%.
