Sodium Naphthalene Formaldehyde SNF-C is used as concrete additive
Naphthalene series superplasticizer is a condensation of
naphthalene sulfonate formaldehyde which is obtained by sulfonation
and condensation reaction of industrial naphthalene as raw
material. This series of products have good adaptability to cement,
strong dispersion effect, no retarding. Low bleed air, high water
reduction rate, plastic protection early strength enhancement. The
workability of newly mixed concrete can be greatly improved by
using this agent. Increase slump, reduce water-cement ratio,
increase concrete compactness, can adapt to various conditions of
concrete construction, to ensure the performance of hardened
concrete.
Naphthalene series of high efficiency water reducing agent and
early strength agent, antifreeze, etc., can be used in low
temperature, negative temperature concrete construction; According
to the engineering needs can be combined with other admixtures into
compound admixtures use.
Used in industrial and civil buildings. Water conservancy, electric
power, airports, ports, Bridges, mines and other projects of
precast or cast-in situ concrete, reinforced concrete and
prestressed reinforced concrete, especially suitable for reinforced
concrete dense reinforced concrete members and structures, so that
concrete easy to pour, construction quickly, easy to ensure the
quality of concrete; It is suitable for the construction of
commercial concrete, pump concrete and high efficiency concrete. In
high temperature weather combined with retarder can be used for
large alkali component, large volume concrete and special
requirements of concrete construction; It is used for the
construction of concrete under normal temperature, high
temperature, or even negative temperature (air temperature is not
less than -3℃). It is also suitable for the construction of
high-strength, high-density, high-impermeability (S20~S30) and
steam cultured concrete with large mobility.
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.
