FAQ
Q: What are the main advantages of powdered water reducers over liquid water reducers?
A: Powdered water reducers offer significant advantages, including low transportation costs (no water required for transportation), convenient storage (no need for frost protection or insulation), a long shelf life, and flexible metering (especially suitable for small-scale or on-site mixing).
Q: How compatible is this product with cement? How can incompatibility issues be avoided?
A: This product's unique molecular design ensures excellent compatibility with most common cements. We strongly recommend conducting a compatibility test before use. We can provide free samples and technical support to ensure optimal compatibility.
Q: What should I do if bleeding, compaction, or other problems occur during use?
A: This is usually due to excessive dosage, inaccurate metering, or insufficient mixing time. Please contact us immediately, and our technical support team will provide professional on-site diagnosis and solutions.
Q: Can it be combined with other admixtures (such as retarders and accelerators)?
A: Yes, but compatibility and optimal mixing ratios must be determined through testing. We can provide professional mixing guidance based on your needs.
