Technical Principle
The main chains of the high performance polycarboxylate water reducing agent molecular are absorbed onto the surface of the cement granules, which can effectively hinder the hydration, enhance fluidity retention ability, the branch chains surrounded by the cement granules, play dual roles of steric hindrance and electrostatic repulsion, it is totally different from conventional water reducing agents, so the high performance polycarboxylate water reducing agent has better dispersion and water reducing effect.
Advantages/Characteristics:
PCE Flake with solid content: 97% min. (Completely soluble in water. If it is used for ready mix concrete or precast concrete, please add PCE flake to water to get a solution with solid content 20% or 10% before use ).
(2) With a good dispersion, an excellent adaptability to different cements, and high water-reducing properties.
(3) With a good slump retention ability, enhance cohesion, without concrete segregation.
(4)Having a thermostability to 50℃ (fifty degree celsius centigrade).

Application
PCE Flake is applicable to various ready mix concrete for industrial and civil architectures, especially to low grade commodity concrete.
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 powers etc.
It is applicable to the special concrete, such as high strength, high durability, self-compacting concrete.
Usages and Cautions:
(1) A recommended dosage is 0.1%-0.5% by the weight of cementitious materials. Optimized dosages should be determined by mixture design test.
(2) Tests must be carried out before utilization.
(3) PCE Flake is forbidden to be mixed with naphthalene sulphonate.
(4) Compatibility test must be done when it is used together with other admixtures.
