Polyocarboxy acid superplasticizer
Highly-efficient polyocarboxy acid superplasticizer differs
from normal superplasticizer through its constitution of unique
polyocarboxy which has long graft chain. It can largely improve
the dispersing capacity of cement as the existence of graft
chain connecting with polymer backbone produced a space limit
that maintained the dispersing and separating capacity of cement
while static disperse occurs at the beginning of stirring procedure.
So that the water needed to maintains the fluidity of the concrete
can be largely reduced.
Features
Largely increase premier and final compressive strength of cement
Increase the folding strength of cement
Improve the Elastic modulus of cement
Lower permeability
Better resistance against aggressive air environment
Lower shrink
Increase durability
Good compatibility with cement and other kinds of cement additives
Usage
Highly-efficient polyocarboxy acid superplasticizer is especially
designed for places that have demand for higher premier and
final compressive strength, for which the typical applications
are:
Self-sealed cement
Pumped cement
Cement that needs to maintain slump constant for a long time
High performance Cement
precast concrete
Application
* It should be put into mixing water when used in mixing station.
* When used in applications such as spot precast mixing sand,
it can be put directly into cement stir truck, and stir it
well for 5 minutes.
* Dosage is approximately 0.6%~1.0% of cement quantity.
Note
* It should be kept at 2℃~50℃, and shelf life is 24 months.
* Although it should not be considered as dangerous good,
it can not be swallowed or contact with skin of eyes.
* It is non-flammable as it is water-based.
