Suplast®  SPT-MSA40

Adjustment of workability

   Suplast® SPT-MSA40 is a special type of polycarboxylate . Its unique formulation is based on the polycarboxylate technology. SPT-MSA40 meets the requirements of GB8076-2008, standard of the P. R. of China.

 Applications SPT-MSA40 is used to improve the viscosity of concrete mixtures, combined with the normal types of polycarboxylate.

When concrete mixtures dosed with other admixtures display segregation, water bleed or settlement, SPT-MSA40 can be used to replace part of the original polycarboxylate  to improve the workability, and completely eliminate  segregation, water bleed or settlement of the concrete mixtures.

 Performance with more than 25% water reduction rate, it is suitable for all types of cement .
 Benefits The superplasticizing and viscosity-adjusting action allows for the production of high slump flowing concrete with excellent workability and slump retention even at a very low water/cementtitious materials ratio. The dispersing action maximizes cement hydration efficiency and improves early and long term compressive strengths of the concrete .

SPT-MSA40 does not contain  any other intentionally added chlorides and will not initiate corrosion on steel reinforcement in the concrete.

How to use SPT-MSA40 is usually used to combine with other normal polycarboxylate-based admixture(10%-15% is SPT-MSA40) to effectively improve the workability and viscosity of concrete mixtures. The  dosage of the combined-admixture  can be much larger than normal polycarboxylate-based admixtures, without concern of segregation, water bleed or settlement because of over-dosage. It is possible to obtain much higher water reduction (up to 45%).
Specification Concentration: 30%

Specific gravity: approx.1.08 

Appearance Yellowish liquid
Package 30kg,250kg barrels and 1000kg tanks are available for export.

        SPT-MSA40 is a concentrated product with 30% of solid.  It is not directly used for concrete mixing. SPT-MSA40 is  usually diluted with water and combined with other polycarboxylate-based admixtures. The appropriate  concentration of application is about 20%.

        Technical supports for applications are always prompt, effect and satisfied from our experienced engineers.
