Description
JK**4
PL isa high
performance based on polycarboxylate, specifically developed as
effective dispersant,fluidized and high range water reducing
concrete agent.
Uses
JK**4PL can be applied
in a wide variety industry and can improve the workability to the
concrete and to improve high early compressive strength, even with
low water/cement ratios while maintaining normal levels of
workability.
It can be widely used in
conventional concrete, pumping concrete, super-fluid
self-compacting and high-performance concrete; it has the excellent
performance especially in the application of high-strength high
performance concrete.
Advantage
1. High
water reducing rate and excellent plasticizing
effect.
2. And
produces concrete with high levels of workability without
segregation.
3. Excellent
dispersion and self-compacting effectcan
produce different grade strength super fluid self-compacting
concrete.
4. Can
be a substantial increase in early and late strengths of
concrete, so that increase the project
construction schedule.
5. Better
plasticity-maintainingcould significantly
prolong the transit time of concrete, it reduce economic losses and
ensure the normal pumping of concrete.
6. Improves
the frost resistance and carbonation resistance of the
concrete. Lower drying shrinkage of the
concrete by *0% or more compared with naphthalene-based
admixtures.
7. High
applicability: It can be used with different
variety of cement.
8. Improved
finished concrete surface ability.
9. Proffer
air environment protect.
*0. No
chloride ions and no corrosion to steel
bar.
Dosage
0.*5– 0.7% by weight of
cement. Standard water reduction at normal
dosage and significant water reduction at higher dosage. 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.
