Retarders
Sodium Gluconate Retarder
- Sodium gluconate
- High-efficiency retarder
- Powder or liquid
- Volume discount
A high-efficiency retarder based on sodium gluconate that markedly delays initial and final set and lowers hydration temperature rise, with better dosage sensitivity than molasses-based retarders.
Strong set delay · lower heat of hydration · temperature-tolerant
- Form
- Powder (liquid also available)
- Recommended dosage
- 0.05%–0.30% of cementitious material
Overview
Sodium-gluconate-based retarder that adsorbs onto cement grains to slow C3S hydration and extend setting without harming late strength. Better dosage sensitivity than molasses retarders.
Key benefits
- Markedly delays set and lowers hydration temperature in mass concrete
- Preserves slump during hot weather and long haul
- Chloride-free, no rebar corrosion risk

Product Q&A
What is the recommended dosage?
0.05%–0.30% of cementitious material; confirm by trial mix with your cement.
Can it be compounded with PCE superplasticizer?
Yes, it is highly compatible with PCE; adjust dosage to control retardation.
