Uses
JK**8NP 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 ***0 centigrade degree.
Not suitable for being solely applied in the
steam curing concrete.
Test before applied in anhydrite, dross or
similar industrial waste cement.
Advantage
1. 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.
2. Increases
initial workability.
High ultimate strengths.
3. The
concrete of compressive strength, flexural, tensile, impermeability
and durability are significantly improved and
enhanced.
4. The
concrete setting time prolong **3h, it can also be adjusted according to the user's
demand. It has not affected the strength growth of concrete at
different time.
Dosage
0.**1.2% by weight of cement.
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.
