Products Description
Concrete additives chemical admixtures polycarboxylate based superplasticizer concrete is a new generation Eco-friendly high performance polycarboxylate superplasticizer developed by our company with DD-912 (EPEG 3000, C6 polycarboxylate ether monomer ) as main raw material.
Technical Principle
The molecular chain of PCE is comb shape. The main chains of the high performance polycarboxylate superplasticizer molecular are absorbed onto the surface of the cement granules, which can effectively hinder the hydration, enhance its flowing retention ability, the branch chains surrounded by the cement granules, play dual roles of steric hindrance and electrostatic repulsion, it is totally different from the conventional water reducing agents. So the high performance polycarboxylic ether based superplasticizer has better dispersion and water reducing effect.

Characteristics
1. Increase setting time at elevated temperatures.
2. Superior slump retarding property: Excellent slump retention performance, particularly, it improves the slump retaining properties of high workability of concrete, while not influencing the normal setting of the concrete.
4. Good cohesion: It has good cohesion to the concrete, which makes the concrete have good workability, no segregation, no bleeding.
5. Good dispersion: The concrete has very good fluidity, easy to cast and compact, adaptable to self-compacting concrete.
6. Wide adaptability: It has wide adaptability with good dispersion and flowing retention ability to varieties of silicate cements, common silicate cements, slag silicate cements and various admixtures.
Application
1. It 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. It is applicable to the special concrete, such as high strength, high durability, self-compaction concrete.
Usage:
1. Generally, it should be mixed with water reducing type PCE according to a certain proportion. The dosage range of water reducer is 0.3%—0.8%, it can beyond this range properly for special cements or aggregates.
2.The compounding rate for specific cements is determined by tests. Recommended stirring time for its concrete stirrer is at least 150s for good water reducing effect. The concrete mixing tests should be carried out before using so as to assure the concrete quality.
