      Suplast®  SPT-A80D

      Formula for precast concrete products

         Suplast® SPT-A80D is a high range water-reducing admixture . Its unique formulation is based on the polycarboxylate technology. SPT-A80D meets the requirements of GB8076-2008, standard of the P. R. of China.

       Applications SPT-A80D is recommended for high strength precast concrete products, appropriate slump retention, and increased early/ ultimate strengths are required. SPT-A80D can be used for production of High Performance Concrete (HPC) of high flow and low ratio of water to cementitious materials, as well as for production of conventional slump concrete.
       Performance The fluidity of cement paste dosed with SPT-A80D shows the performance as follows.

       Benefits When used as a high range water reducing admixture, water reduction up to 35% can be obtained. The superplasticizing action allows for the production of high slump flowing concrete with excellent workability even at an extreme low water/cementitious materials ratio. The dispersing action maximizes cement hydration efficiency and obviously increases early and long term compressive strengths of the concrete .

      At a lower dosage,  SPT-A80D can be used as a cost effective mid range water reducing admixture (about 20% water reduction) for production of conventional slump concrete. SPT-A80D will improve workability and finishability.

      The combined water reducing and superplasticizing action provide the following benefits:

      .Increased slump improves workability and reduces labor costs.

      .Much higher early and ultimate strengths for cost effective high strength concrete and
      earlier structural use of concrete.

      .Accelerated early strengths allow faster demolding and more efficient use of forms to
      precast producers.

      .Higher concrete density reduces permeability and increases durability.

      SPT-A80D does not contain  any other intentionally added chlorides and will not initiate corrosion on steel reinforcement in the concrete.

      Dosage For concrete with compressive strength of 30Mpa-50Mpa, the dosage is 0.12%-0.18%(in solid) of the weight of cementitious materials. For concrete with strength more than 50Mpa, the dosage is 0.20%-0.30%.
      Specification Concentration: 40%-50%

      Specific gravity: approx.1.16-1.20 

      Appearance Yellowish liquid
      Package 30kg,250kg barrels and 1000kg tanks are available for export.
      Shelf life When stored in dry and cool warehouses, the shelf life is 24 months.

              SPT-A80D is a concentrated product with 50% of solid for lower-cost delivery. It can be directly used for concrete mixing, but  usually diluted with water before use.  The appropriate  concentration of application is about 20%.

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