JK*2 high range water reducing admixture is the non-air entraining
high range water reducing admixture by chemical ***** chemical name
is β-naphthalene sulphonic sodium formaldehyde admixture. It has a
powerful dispersion effect for the cement particle. It can improve
the performance of the concrete and good for the preparation of the
great liquid concrete, the precast component and the cast-in-place
concrete which demand the early strength and high strength, it
applies for road, bridge, dam, port, dock, tunnel, electric project
and water project, industry, civil construction, steam curing and
nature curing precast component etc.
Homogeneity of Norms:

Moisture content â?¤*0% Fluidity of cement **0mm
Finesse 0.**5mm sieveâ?¤*2% Foam-breaking
time â?¤*0seconds
Principal Technical Performances:
1. The mixing amount is 0.**1.5% of the cementitious material; the
water-reducing rate is ****8%. This product has clear early
strength and reinforced effect, concreteâ??s strength will improve
*****0% for 3 days, improve ****0% for 7 days, improve ****0% for
*8 days, and the strength will be increased for a long period.
2. This product can save cement ****0% than the concrete without
the water reducing adnixture in keeping the same intensity and
slump of concrete.
3. Mixing this product can greatly improve the workability and the
mechanical performance and improve the anti-pressure, anti-pull,
anti-fold intensity, elastic modulus and long period intensity.
4. The product is adaptable for the different cement. For example:
silicate cement, ordinary silicate cement, slag cement and
pozzolana cement etc.
5. The product is adaptable for high strength concrete, flowing
concrete, early strength concrete, precast steam curing concrete,
prestressed concrete etc.
6. This product is divided the powder and the liquid, the liquid
content is *0±2%, the proportion �1.*2, the admixing content is
1
