Factory supply Water Reducer FDN-C naphthalene sulphonate Formaldehyde
Product Detailed
Water Reducer FDN-C 1>Powder;liquid 2>Non-flammable;non-corrosive 3>Remarkable Plasticity 4>Water Reduction 19%min

Product Name: Water Reducer FDN-C Naphthalene Sulphonate Formaldehyde

Properites:

 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 16-22% when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression strength on the lst day, the 3 rd day and the 28 th day after single application 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 collapsibility as well. As a condition of equivalent blending, collapsibility can be increased 4-6 times when it is added at 0.7% blend dosage.

4. 15-18% of cement can be reserved when the agent is blended at 0.7% blend dosage, which is preconditioned by same collapsibility and strength.

Note: Standard Blend Dosage: 0.70% (AS CEMENT AMOUNT)

USAGE:

Blending dosage at 0.5%-1.0%, 0.7% mixing dosage advised.Prepare solutions as required.Direct use of powder agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%).The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.

PACKAGE:

Package:

Powder: Packing in woven fabric bag with plastic inner. Net weight: 25kg±0.2kg or 50kg±0.2kg or 750kg±0.2kg

Liquid: Sealed plastic drums to prevent accidental leakage and evaporation. The material can be delivered or transported by tank car.
