3. Performance and use
This product is yellow powder, an anionic surfactant, soluble in water, acid, alkali and hard water.
1. can save water 10%min
2.can improve the workability of concrete substantially
3.the pressure resistance can be improved by 15%min after 3-28days
4. can lower the concrete’s heat of hydration
5.no corrosion to steel bar
6.usually 0.2-0.5% of concrete’s weight should be put, but the ratio can be adjusted according to the test.
7 can be used after made into solution, also can be put directly into agitator with concrete, but need to stir for longer time a little.
8. will have a better effect if used together with high effective naphthalene water reducing agent. The ratio should be adjusted according to the kind of concrete, aggregate and naphthalene’s type.
9.the adding quantity should be accurate, if less the effect will not be visible if more the early strength will be effected
NOTICE:
10. this water reducing agent should not be used alone if the temperature is below 5degree centrigrade.
11,better to test before large scale using.
12. if used this water reducer alone,the dosage should be aroud 0.25%, can not exceed 0.3%.
4. Package: 25KG plastic woven bag with plastic lining.
5. non-toxic, non-inflammable, non-explosive.
