Suplast®  SPT-B2060

Time-Released Admixture

   Suplast® SPT-B2060 is a time-controlled admixture . Its unique formulation is based on the polycarboxylate technology. SPT-B2060 meets the requirements of GB8076-2008, standard of the P. R. of China.


 Applications SPT-B2060 is used for prolonged slump retention of ocncrete, such as  ready-mixed concrete. SPT-B2060 must be combined with the high water reducer (15%-30% substitution of the later)) .

Some retarders (such as Sodium Gluconate) may be added for ready-mixed concrete to prolong the setting times because SPT-2060 does not change the set time.
 

 Performance The fluidity of cement paste dosed with SPT-B2060 shows the performance as follows.

 Benefits The Combined Admixture of SPT-B2060 and the high water reducer allows for the production of high slump flowing concrete with excellent workability and prolonged slump retention that can be placed with less vibration even at a very low water/cementtitious materials ratio. The dispersing action improves cement hydration efficiency and increases early and long term compressive strengths of the concrete . Prolonged slump retention does not have negative effect on set times.

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

.Prolonged slump retention will extend workability and make pumping-transfer easily. 

.Increased slump improves workability and reduces labor costs.

.Without bleed or segregation usually caused by time-released effect, Higher concrete density reduces permeability and increases durability.

SPT-B2060 does not contain  any other intentionally added chlorides and will not initiate corrosion on steel reinforcement in the concrete.

        SPT-B2060 is a concentrated product with 50% of solid for lower-cost delivery. It is not directly used for concrete mixing. SPT-B2060 is  usually diluted with water and/or combined with some retarders (sodium gluconate etc.) in order to prolong the set times for long-distance transport or some special purposes. The appropriate  concentration of application is about 20%.

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