Sodium Naphthalene Formaldehyde SNF-C is used as concrete additive
Naphthalene series superplasticizer is a non - entrained
superplasticizer synthesized by chemical industry. Chemical name
naphthalene sulfonate formaldehyde condensates, it has a strong
dispersion of cement particles.
Main technical performance:
1. This product conforms to the national first-class standard of
wet soil admixture GB8076-2008.
2. The technology amount is 0.5-1% of the water wave consumption,
and the water reduction rate is 16-22%; With appropriate dosage,
the strength of warm set soil can be increased by 60%-95% in one
and three days, 25%-40% in 28 days, and the long-term strength is
still improved.
3. Under the same water-cement ratio, the collapse of SNF-C(0.75%)
is 4-6 times higher than that without SNF-C. Retained its
plasticity, 4, when the clay concrete intensity, farm fall at the
same time, should be the basic phase search into the SNF - C, can
save 15% 18% cement.
5. Improve workability and various mechanics and structural
properties of concrete components, improve workability,
impermeability, durability, and have certain frost resistance.
6. SNF-C has a wide range of applications, especially suitable for
preparation of high-efficiency, ultra-high strength concrete: steam
cured concrete, fluid concrete, impervious concrete, waterproof
concrete, plasticized concrete, reinforced concrete and prestressed
reinforced concrete
Instructions for use:
1. The dosage of this product is generally 0.5%-1.0%, and the
recommended dosage is 0.75%.
2. This product can be used as solution or dry blending method.
3. Mixing type concrete transporter, also can be added during
construction.
Please note: when using this product for the first time or
replacing cement varieties, necessary concrete experiments should
be done according to the specific conditions and requirements of
the project. In the construction process, pay attention to the
actual performance of FDN-B mixing, summarize the practical
experience effect to make adjustments, in order to obtain the best
results. Reasonable maintenance conditions and systems should also
be determined during steam maintenance.

Packaging and storage
1. Powder products are made of chemical fiber woven bags, lined
with plastic film bags, each bag net weight (40±0.2kg) or
(25±0.2kg) or (750±0.2kg), can also be customized according to
customer requirements.
2. Powder products should be stored in dry and ventilated special
warehouse, products such as damp caking can be crushed or dissolved
into water agent use does not affect the actual effect.
