◆Low dosage (0.03%~0.05%): Mild retarding effect. It only slightly extends setting time and mainly keeps slump stable.
◆Regular dosage (0.05%~0.10%): Stable retarding performance, the most widely used range for construction projects.
◆Excessive dosage (>0.15%): Setting time will be significantly prolonged, resulting in severe over-retardation and low early strength.
Recommended dosage: 0.03% ~ 0.10%, optimal range: 0.05% ~ 0.08%
Initial setting time extension:
0.03%: 2 to 4 hours (e.g. from 5h to 7~9h)
0.05%: 4 to 8 hours (e.g. from 5h to 9~13h)
0.08%: 6 to 12 hours (e.g. from 5h to 11~17h)
0.10%: 8 to 16 hours (e.g. from 5h to 13~21h)
If the dosage exceeds 0.15%, retarding effect becomes extremely strong. The setting time can reach 24~48 hours, even over 60 hours. Early strength will obviously drop, so please strictly control the dosage.
◆Stable performance at high temperatures
For summer construction at 30~38℃, it prevents rapid setting and cold joints. For example, at 35℃ with 0.08% dosage, the initial
setting time extends from 6 hours to 12 hours.
◆Ideal for mass concrete
It extends the workable time, reduces peak hydration heat, and reduces thermal cracking.
◆Excellent slump retention:
It greatly reduces slump loss and is perfect for 2~4-hour long-distance transportation.
◆Eco-friendly
Non-toxic, non-corrosive, and easily biodegradable, complying with green chemical standards.
1. Q: What are common issues and remedies?
A: Common issues include excessive setting retardation and reduced slump.
Solutions: reduce the sodium gluconate dosage, adjust the superplasticizer proportion, or change the addition sequence. Always
run tests to confirm the effect.
2. Q: Can it be used with sulfate-resistant or high-alumina cement?
A: It works well with most types of cement. However, cement with different compositions will affect retarding and chelating
We suggest doing mixing tests and adjusting the dosage accordingly.
3. Q: Does it affect freeze–thaw resistance and durability?
A: Proper usage won't reduce concrete durability. It helps make the pore structure more uniform and even improves durability.
Please optimize dosage and mix proportion to avoid negative effects on freeze-thaw resistance.
4. Q: Is it compatible with common water reducers (PCE, naphthalene-based)?
A: Sodium gluconate is generally compatible with PCE and naphthalene-based plasticizers. It improves their dispersion and slump
retention. Please run lab or on-site tests to find the best mixing ratio.
5. Q: How to obtain technical datasheets and samples?
A: Feel free to contact our sales or customer service for TDS, MSDS, and free samples. We also offer mixing test support and
formula suggestions.
