GNS-101 Pumping Agent of Poly-carboxylate Super-plasticizer

Product name ,Chief constituents,Technical indicator

1,Product name: Pumping Agent of Poly-carboxylate Super-plasticizer

2,main chemical compositions:Poly-carboxylate Super-plasticizer,protect collapse agen,Retarder,Air entraining admixture

3,executive standard: JG473-2001<Concrete Pumping Aid Agents>

                       GB8076-2008<concrete admixture>

product purpose:

    This product is used in all kinds of C15~C40 Grade pumping concrete.

Product technical performance:

  1.our product is light yellow liquid,no crystallization,no sediment,formaldehyde-free,to be considered as Green Environmental Production.

  2.with the quantity binding materials 1.2%,water-reducing rate is15%;water-reducing rate18%.

  3.the slump constant value added and retention value can reach to JC473-2001 Grade A standard with this product in concrete

   4.it can regulate the time of delayed coagulation in summer or mass concrete construction,the final set time will be lasted for 6-10 hours.

  5.It will not effect concrete pumping performance which without any crystallization and sedimentation in winter.

  6.It has good weather ability and corrosion resistance with chlorine ion content≤0.02%,Alkali amount≤0.1kg/m3

Attention:Homogeneity Performance and Mechanical properties of concrete by GB8077-2007,JG/T223-2007<poly-carboxylates high performance water-reducing admixture>

Recommended mixing amount:

Recommended mixing amount of concrete as bellow:

Optimum mixing amount :0.8%~2.0%(10% Solid content);Recommended mixing amount1.5%.

Attention:mixing amount must be binding experimented based on raw material properties,concrete mirtune and climate.

Construction method:

1.this product can’t be mixed with Naphthalene series products, pail pack,blender need to be cleaned out before using .

2.We need to try matching to confirm the adaptability of cement Mixing dosage.

3.Using this product with exact metering,without less or mis-mixing ,it can be mixed into concrete with water, it’ll work more efficient.

4.If the intensity of concrete is above C40 Please use GNS-102 Pumping Agent of Poly-carboxylate Super-plasticizer.

Packaging and storage period:

1.It is packed by 200kg Plastic barrel or 1000kg Tons of plastic bucket,it is also customized

2.storage period:two months for summer,three months for winter. Avoiding contamination,avoiding mixed with naphthalene series.
