FDN-A High-Efficiency Superplasticizer
1. Properties, Features & Characteristics(FDN-A)
1) Appearance: Light brown powder & dark brown liquid. Non-poisonous, odorless, non-flammable and non-corrosive 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 18-28% when it is admixed with reinforced concrete at 0.5%-1.0%.Statistically, compression strength on the 1
st day, the 3
rd day and the 28
th day after single application is increased by 60%-90% and 25%-60% 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 collapsibility as well. As a condition of equivalent blending,collapsibility can be increased 5-8 times when it is added at 0.75% blend dosage.
4) 15-20% of cement can be reserved when the agent is blended at 0.75% blend dosage,which is preconditioned by same collapsibility and strength.

4. Usage
1) Blending dosage at 0.5%-1.0%,0.75 mixing dosage advised.
2) Prepare solutions as required.
3) Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%)
4) The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.

5) Appearance: Light brown powder & dark brown liquid. Non-poisonous, odorless, non-flammable and non-corrosive to steel bars.
6) Remarkable Plasticity: As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 17-25% when it is admixed with reinforced concrete at 0.5%-1.0%.Statistically, compression strength on the 1
st day, the 3
rd day and the 28
th day after single application is increased by 60%-95% and 25%-50% 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.
7) Improve miscibility of concrete amalgamator with water and collapsibility as well. As a condition of equivalent blending,collapsibility can be increased 4-7 times when it is added at 0.75% blend dosage.
8) 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.
