Naphthalene-based High range Water reducing and Set retarding Concrete admixture

High water reducing
Delay setting time
High effective superplaticizing effect
Improve workability
Promote early strength
Description
JK-08NP
is a
water reducing
,
highly effective superplasticizer

with
a set retarding eff
ect

for concrete in hot temperature which
delays concrete setting time
. It has also
high range water reducing for promoting high early and ultimate strengths of concrete.
JK-08NP is naphthalene-based superplasticizer compounded by some of high-performance retarder, stabilizer and reinforcing admixtures etc. It complies with ASTM C 494 Type G, GB8076-2008 and GB50119-2003.
Uses
JK-08NP is
ideal concrete admixtures for preparing high-performance and high-strength concrete, mass concrete and long-distance transport concrete etc
.
It is
suitable for working condition under temperature 5-40 °C.
Not suitable for being solely applied in the steam curing concrete.
Test before applied in anhydrite, dross or similar industrial waste cement.

Advantage
Has a high efficiency water-reducing
,
retarding in the initial setting and early strength in final setting, late-enhanced, less slump loss
etc. which is extremely beneficial to the transport and to pouring of concrete.
Increases initial workability
.
High ultimate strengths
.
The concrete of compressive strength, flexural, tensile, impermeability and durability are significantly improved and enhanced
.
The concrete setting time prolong 1-3h
, it can also be adjusted according to the user's demand. It has not affected the strength growth of concrete at different time.

Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.Using during mixing and after-mixing method and properly prolong stirring time to assure even.
