Advantages in cement
1. Low dosage 0.3~0.75% of the weight of cementitious material .
2. Water reducing rate 25~35%.
3. Wide adaptability, can used in all kinds of concrete projects and cement products.
4. Meet the international standards environmental protection rules: ISO14000.
5. High slump retention, slumps keep unchanged within 30min and loss little in 1h
6. Low shrink rate with Polycarboxylate superplasticizer.
7. Improves the liquidity of concrete greatly.
8. Makes the concrete keep long time construction performance.
9. Ameliorates the peaceability and physics performance of concrete, improving construction quality.

Applications
?
1. Used as high range water reducer. It produces concrete with extremely workable characteristics referred to as high slump. It also allows concrete to be produced with very low water/cement ratios at low or normal slumps. Their ideal for use in prestress, precast, bridge deck or any other concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
2. It can be added directly or added in after dissolved. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%.
3. Also used as dispersant agent in textile, dyes industries.
