Product Description

FDN-C Naphthalene sulphonate formaldehyde

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.
