FDN-C High-efficiency superplasticizer
(I) Properties, Features &Characteristics(FDN-C)
1. Appearance:Light brown powder &dark brown liquid. Non-poisonous,odorless, non-flammable and non-corrossive to steel bars.
2.Remarkable Plasticity:As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 16-22%when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the 1st day, the 3rd day and the28th day after singleapplication is increased by 60-95% and 25-40% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength,buckling strength and modulus of elasticity will be improved to some extent.
3.Improve miscibility of concrete amalgamator with water and cillapsibilityas well. As a conditionof equivalent blending, collapsibility can be increased 4-6 times when it is added at 0.75% blend dosage.
4.15-18% of cement can be reserved when the agent is blended at 0.75% blend dosage,which is preconditioned by same collapsibility and strength.

(IV) Usage:
1. Blending dosage at 0.5%-1% mixing dosage advised
- Prepare solution at required
- Direct use of powder agant is allowed. Alternatively the addition of the agent is followed by water moisturiztion(water-cement ratio:60%)
- The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
(V) Packing, Storage and Transportation
1.Package:
Powder:packing in woven fabric bag with plastic inner.Net weight:25kg±0.2kg,50kg±0.2kg,750kg±0.2kg
2.Caution:
Prevented from being torn by sharp-endobjects while package are being transferred or delivered.When being contained by high humidityor moisture in case of leakage, it can be prepared in prescribled ways for further use without surrending any effect.
3.It should be stored in a decicated warehouse that is well venilated and dry. If be affected with damp, just samesh or melt it into solution without any bad effection.
