Advantages/Characteristics:
1. Increase the setting time at high temperature.
2. Excellent retardation performance: excellent slump retention performance, especially improving the slump retention performance of high workability concrete without affecting the normal setting of concrete.
3. Good adhesion: It has good adhesion to concrete, so that the concrete has good workability, no segregation and no bleeding.
4. Good dispersibility: Concrete has good fluidity, is easy to pour and compact, and is suitable for self-compacting concrete.
5. Wide adaptability: It has good dispersion and flow retention ability for various Portland cement, ordinary Portland cement, slag Portland cement and various admixtures, and has wide adaptability.
7.The supersustained-release functional group is introduced, and the sustained-release time is longer than that of conventional mother solution, and the overall retention time is longer.

Usage
1. Generally, it should be mixed with water-reducing PCE in a certain proportion. The dosage range of the water reducing agent is 0.3% ~ 0.8%, which can be appropriately exceeded for special cements or aggregates.
2. The proportion of specific cement was determined by experiment. It is recommended that the mixing time of its concrete mixer is at least 150 seconds to achieve a good water reduction effect. Concrete should be tested before use to ensure the quality of concrete.
Application
1. long Slump Retention Type PCE is applicable to various ready mix concrete for industrial and civil architectures.
2. It is particularly applicable to various national construction works with high performance requirements for the concrete , such as water industry, marine works, seaports, traffics, electric powders etc.
3.long Slump Retention Type PCE is applicable to the special concrete, such as high strength, high durability, self-compaction concrete.
