Packaging Details
Woven fabric bag with plastic liner. Net weight: 25kg or 1000 kg; 16MT/20'FCL

FDN-C Naphthalene sulphonate formaldehyde (Concrete Admixtures)


1.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 lst 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.
2. 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 0.7% blend dosage.
3. 15-20% of cement can be reserved when the agent is blended at 0.7% blend dosage, which is preconditioned by same collapsibility and strength.

RACKGING, TRANSPORTATION AND STORAGE

 1.Woven fabric bag with plastic liner. Net weight: 25kg±0.13 kg or 50 kg±0.25 kg

 2.Cautions should be taken to prevent form being torn by sharp-ended objects while packages are transferred or delivered.

 3.It should be stored in a dedicated warehouse that is well-ventilated and dry. It remains effective for two years. At the expiration, re-use is allowed if the testing results fall within the established range. In case of humidity contamination, re-use is allowed after drying and crushing.
