1. Scope of application
Suitable for ready-mixed high-strength pumped concrete, commercial concrete, large-volume concrete, reinforced concrete, high-fluidity concrete, and self-compacting concrete.
2. Main performance
1. This product is divided into powder and liquid. The powder is brown and the liquid is black. When constructing at negative temperatures in winter, antifreeze types can be used.
2. This product has stable chemical properties, good safety performance, non-toxic, odorless and non-flammable. No crystallization in winter.
3. Water reduction and enhancement effect is good. The water reduction rate is above 22%, and pumpable concrete below C80 can be prepared.
4. Good durability. This product has low alkali content, basically does not contain CLˉ salt, and the shrinkage of concrete is small.
5. Good constructability. This product has an obvious retarding effect, which greatly reduces the early heat of concrete transformation. Its initial setting time is delayed to about 10 hours. It can also be adjusted appropriately according to customer needs. It has no bleeding, no segregation, and good water retention properties. The 2h loss is small and has a certain air content, which improves the flexural performance of concrete, greatly improves the elastic modulus and waterproof and impermeability functions of concrete.
6. This product has strong adaptability to various types of cement, and the effect is particularly good when mixed with ultra-fine mineral admixtures.
3. Performance of ZWL-A-I type multi-functional high-strength and high-performance pumping agent (reference value)

The above are recommended mixing ratios for reference only. When preparing concrete above C50, you must contact the manufacturer and adjust the admixtures accordingly.
V. How to use
1. The dry powder can be directly mixed into concrete for use or used as a solution of a certain concentration, and the liquid can be added directly.
2. When used in combination with expansion agent, the concrete mixing time should be extended by 30 seconds.
VI.
1. The powder is packed in a plastic bag lined with an inner woven bag. The net weight of each bag is 25kg±0.25kg; the liquid is packed in plastic barrels, which must be sealed to prevent leakage or evaporation of water. Tank trucks can also be used for transportation.
2. When transporting the powder, be careful not to encounter sharp objects to prevent the package from being damaged by moisture. If the tide is collected, it can be prepared into a solution with a certain concentration for use without affecting the use effect.
3. It should be stored in a ventilated and dry special warehouse. The validity period is one year. It can still be used after passing the validity period and passing the test.
