Product Details

FDN Naphthalene superplasticizer concrete Additive Superplasticizer

Product Description

Properties,featuers & characteristics(FDN-A)

1.Appearance:Light brown powder & dark brown liquid. Non-poisonous,odoriess,non-flammable and non-corrosive to steel bars.

2.Remarkable Plasticity:As a condition of blending where amount of cement and collapsibility are fixed sforehand,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 last day,the 3 rd day and the 28th day after single application id increased by 60-90% and 25-60% respectively when it is added at standerd blend dosage. As the result,compression strength,tensile strength,buckling strength and modulus of elasticity will be improved to some extent.

3.Imporve miscibility of concrete amalgamator with water and collapsbility as well. As a condition of equivlent blending,collapsibility can be increasrd 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.
