Note: The dosage should be determined according to the material properties of the concrete mix, climate and other binding assays. Construction: This product can not be mixed with naphthalene products, drums, mixers should be clean to use. Ratio for the test before use, to confirm the adaptability and mixed with cement consumption. FDA accurate measurement, essential mixed or misuse mixed, with the incorporation of concrete mixing water at the same time, using the reference method after concrete work better. In high-grade concrete strength C40 above, please use GNS-102 polycarboxylate pumping agent. Packaging and storage of: 1. This product uses 200kg plastic drum or 1000kg plastic ton drum, also can provide a variety of packaging according to user requirements. 2. Storage period: summer months, the winter months to avoid contamination, avoid mixing with naphthalene.
