Polycarboxylic acid high performance water reducer CAS 62601-60-9
Polycarboxylic acid superplasticizer is the third generation of new
superplasticizer for concrete. Compared with naphthalene
superplasticizer, Polycarboxylic acid superplasticizer has the
advantages of high water reduction rate, high strength, low
shrinkage, low secretion and low slump loss. Polycarboxylate
superplasticizer has relatively good adaptability with different
cement. Compared with naphthalene superplasticizer, the strength of
polycarboxylate superplasticizer concrete increases faster in early
and late periods, especially the strength of high-strength concrete
increases more obviously in late periods.
Use
This product is suitable for improving the performance of polyether
superplasticizer, including improving the adaptability of polyether
superplasticizer to cement in concrete, improving the stability of
water reducing agents, reducing concrete bleeding, reducing high
grade concrete viscosity, and improve concrete pumping. This
product can also reduce the amount of water-reducing agent.
Characteristics
1. Improve the adaptability of cement
2. Reduce the slump loss; incorporation of pumping agent can reduce
the loss of slump
3. Reduce bleeding
4. Reduce the viscosity of concrete; the preparation of high-grade
concrete, can reduce the viscosity of concrete, improve pumping;
5. Reduce the amount of superplasticizer: the addition to this
product, the superplasticizer in the concrete content can be
reduced;
6. Green products: the production and use of the product does not
produce pollution of the natural environment, in line with ISO14000
environmental protection and management of international standards.

Use recommendations :
When used alone or combined with other varieties of polycarboxylic
acid water-reducing agent (mother liquor), the mixture amount of
folding-solid should be 0.05%~0.25% of the cementing material, and
then added into the mixer with water after proportional dilution.
If necessary, appropriate amount of entraining, defoamer, retarding
and other components can be added to adjust the relevant
properties.
