13. Frequently Asked Questions (Technical Terminology)
Expert FAQ: Understanding PC-733 Polycarboxylate Water Reducing Agent
- Q1. What is the primary material composition of PC-733 Powder Polycarboxylate Water Reducing Agent?
- It consists of specially engineered polycarboxylate ether copolymers (PCE) with high-purity PEG side-chains and tailored molecular weights. This provides maximum steric hindrance effect for superior water-reducing performance.
- Q2. What do the ISO and EN 934-2 certifications guarantee?
- ISO 9001 ensures a robust quality management system; EN 934-2 and ASTM C494 certify compliance with the latest superplasticizer standards for safety, water-reduction, and slump retention requirements.
- Q3. What does "slump retention" mean in context?
- It's the ability of concrete to maintain its initial workability (consistency) for a specified time (e.g., 2 hours) after mixing. High retention is critical for long-distance transport and hot climates.
- Q4. How does PC-733 enhance corrosion and sulfate resistance?
- PC-733 significantly lowers water/cement ratio, leading to a denser matrix and dramatically reducing permeability. This blocks chloride and sulfate ingress—the root cause of steel rebar corrosion in aggressive environments.
- Q5. What is the best recommended dosage?
- Between 0.15%–0.3%, depending on binder type, ambient temperature, and required fluidity. Always calibrate in advance via local laboratory mix trials.
- Q6. How is product shelf life verified?
- Stability testing is conducted per ASTM D-3078 and ISO 15547. PC-733 remains effective for 12 months in vacuum-sealed packages under normal warehouse conditions (≤35°C, ≤75% RH).
- Q7. Does PC-733 cause rapid or delayed setting?
- No. PC-733 PCE typically shows neutral setting behaviour in ordinary Portland, blended, or sulfate-resistant cements, provided dosing guidelines are followed.
