GR-P5 Polycarboxylates High-performance Water-reducing Admixture – 081235306266 (WA)
GR-P5 is high-performance aqueous dispersion agent, which is special designed for self-compacting concrete, high-performance concrete and precast components. GR-P5 is key ingredient in admixture of concrete.
It can improve the flowability of concrete while significantly reduce the mixing water of concrete. It has high water-reducing rate to meet the performance requirements of self-compacting concrete, high-performance concrete and precast. And it also has the function on early strength.
Natural Characteristics：Polycarboxylic acid aqueous solution;
Appearance（20℃）：light yellow to brown liquid;
Solid Content（%）: 40±1%;
PH Value（20℃）: 5~7;

Features of GR-P5
² High water-reducing rate;
² Achieve high efficiency at low dosage;
² Low air-entraining effect;
² Broad adaptability with many kinds of cement;
Advantages of GX-P5
² Improve productivity of the concrete;
² Reduce the comprehensive cost of the concrete;
² Improve the workability of the concrete;
² Promote the growth of the concrete strength;
As polycarboxylates high performance water-reducing admixture, GR-P5 can be used to design high-performance admixture products.
GR-P5 is widely used in the production of self-compacting concrete, high performance concrete and various precast. It can significantly reduce the water consumption and improve the workability and early strength of the concrete.
When GR-P5 is compounded with other varieties of admixture, please pay attention on the compatibility, and it should be tested before used.
Examples of GX-P5: Product in an ready-mixed concrete mixing station, the proportion and performance of concrete are showed in following tables:
Form 1——Concrete mix proportion
|Cement PⅡ 42.5R||400|
|Fly ash Grade I||75|
|Solid dosage of admixture（%）||0.19|
|Initial slump/ Expansion degree(mm)||250/700|
|60min slump/ Expansion degree(mm)||255/670|
|Reflux time of initial slump barrel(S)||5.3|
|Reflux time after 60min (S)||7.1|
|Concrete status||Good parcel and softness|
It can be seen from the above results that the slump degree and expansion degree of concrete formulated with GR-P5 can meet the design requirements, and the concrete shows low viscosity, flow speed and good workability, it is fully able to meet the construction requirements of self-compacting concrete.
