5% sodium sulfate poly naphthalene sulfonate formaldehyde as
concrete additive
------Elt-NSF
1. poly naphthalene sulfonate formaldehyde Introduction
Naphthalene formaldehyde sulphonate water reducing agent is a
synthetic powder based onbeta-sulphonate formaldehyde ondensate and
reactive polymer.
It has the properties of high range water reduction, set retarding
and excellent strengthening.
Elt-nsf sodium sulfate is less than 10% , suitable to middle
strength or high strength
concrete where high range water reduction is desired.

3. poly naphthalene sulfonate formaldehyde Application
A. Used for and widely for self-cured, vapor-cured concrete and its
formulations. At the
early stage of application, extremely prominent effects are shown.
As the result, the modulus and
site utilization can be drastically, the procedure of vapor cure is
omitted in peak-heat summer days. Statistically 40-60 metric tons
of coal will be preserved when a metric ton of the material is
consumed.
B. Suitable for preparation of early-strength, high-strength,
high-anti-filtration and self-sealing& pumpable concrete.
C. Widely used in pre-cast & ready-mixed concrete, armored
concrete and pre-stressed reinforced concrete in key construction
projects such as dam and port construction, road building &
town
planning projects and dwelling erections etc.
D.Compatible with Portland cement, normal Portland cement, Portland
slag cement, fly-ash
cement and Portland pozzolanic cement etc.
4.poly naphthalene sulfonate formaldehyde USAGE:
A. Blending dosage at 0.5%-1.0%, 0.6% mixing dosage advised.
B. Prepare solutions as required.
C. Direct use of powder agent is allowed. Alternatively the
addition of the agent is followed by water moisturization
(water-cement ratio:60%).
