Set Retarder(Sodium Gluconate)
Description
Sodium gluconate is suitable to apply in high temperature season, long distance transportation, and pump concrete; also appropriate for mass concrete, self-leveling concrete and high strength high performance concrete, etc.
Applications
It's widely applied in concrete requiring extended setting time, mould concrete and mass cast concrete.
It can be applied as a retarding component for producing retarding superplasticizer.
Compatible with polycarboxylate, Naphthalene Superplasticizer, and Air-entraining Agent.

Features and Benefits
High workability, no segregation, no water bleeding.
Improve the concrete breaking strength, tensile strength, elastic modulus and adhesiveness to the steel bar.
Improve concrete durability performance, such as anti-seepage, anti-freezing and anti-carbonization.
Avoid cement initial hydration, extending cement and concrete setting and retaining time.
Non-toxicity, non-inflammable, non-corrosion to the steel bar.
Packaging, transport and storage
It's packed in fabric bag with plastic liner. Net weight: 25kg +/- 0.13 kg.
Cautions should be taken to avoid moisture and water while being delivered or storaged, since it's soluble in water.
It should be stored in a dedicated warehouse that is well-ventilated and dry.
