Description
JK**9
NPis naphthalene-based non-chloride set-accelerating
water-reducing admixture, it significantly accelerates setting time, and reduces the quantity of mixing water necessary to
produce concrete of a given consistency, while providing
greater economy for a given strength. It increases strengths and
significantly improves permeability, workability and finishing
characteristics. It complies with GB ********8, GB*********3 and
ASTM C**4, Type E.
Uses
1. This
product is designed for the constructions requiring earlier
strength for normal concrete, steel-reinforced concrete, and
pre-stress concrete under normal temperature, low temperature (*5
to *0 degree C).
2. Widely
used in pre-cast & deposit concrete, armored concrete,
pre-stressed reinforced concrete and fly-ash-cement concrete.
Compatible with Portland cement, normal Portland cement, Portland
slag cement, fly-ash cement and Portland pozzolanic cement
etc.
3. Suitable
for self-cured concrete and its formulations. It has remarkable
effects of water reduction and enhancement, especially at the early
stage. The modulus and site utilization can be
improved.
Advantages
1. Accelerating
setting time across a wide range of temperatures. Increasing early
and ultimate compressive and flexural
strengths.
2. Water
reducing ****5% with low dosage of
1.**2.5%
3. After
application, all physical properties of concrete can be improved to
a certain extent.
4. *0%**5%
of cement will be reservedwhen it is applied as
a condition of blending in which collapsibility and strength are
fixed forehand.
