SUPERPLASTICISER & SET RETARDER (SPSR)


  • SUPERPLASTICISER & SET RETARDER

    CETEX – Super Plasticiser & Set Retarder (SPSR) when added in the cementitious mixture, improves workability of concrete mix for constant water to cement ratio and increases the setting time. It is ideal for Ready Mix Concrete (RMC) plants. It is used as super plasticiser for production of free flowing concrete for slabs, foundations, walls, beams, columns and piers; areas with dense reinforcement. As a water reducing agent it is also used for early and ultimate high strength concrete such as pre-cast concrete, pre-stressed concrete, bridges, cantilever structure and foundations, etc. It complies with ASTM-C-494 Type D/G, IS- 9103 and BS-5075. It complies with ASTM-C-494 Type A/D, IS- 9103.


    DOSAGE

    150 – 400 ml per 50 kg of cement is recommended.

    However, field trials should be conducted to determine the optimum dosage to achieve the required condition of the mix.

ADVANTAGES

  •  It increases the initial setting time, which helps in transportation of concrete.
  • It significantly improves the workability of the concrete mix. In presence of the admixture, the slump value increases resulting in ease of placing the concrete mix.
  • Addition of the admixture can reduce the water content of the concrete mix by 40% or more, which results in more dense concrete, thereby increasing the compressive strength. This improves the durability, impermeability and frost & water resistant properties of the mix.
  • It decreases the amount of vibration and significantly reduces the risk of segregation.
  • Economics in mix design can be achieved by reducing cement usage.



PROPERTIES 

Type                        :      Modified Sulphonated Naphthalene 

                                       Formaldehyde Condensate (SNF)


Colour                     :      Dark Brown/Black liquid

 
Specific Gravity     :      1.20 +/- 0.02 at 25OC

MECHANISM

When Portland cement is mixed with water, the cement agglomerates stick to each other due to insufficient mutual electrostatic repulsion. With the presence of CETEX-SPSR, the attraction between the particles is reduced and the cement particle disperse, hence a more cohesive and consistent mix is achieved.

DIRECTION OF USE

CETEX-SPSR should be added to the concrete mix during the mixing cycle after addition of water. Never add the admixture to the dry mix.

 

PACKING

CETEX-SPSR is available in 25, 60 or 250 kg pack or bulk. Store in frost-free condition away from sunlight or extreme heat. For best result, use within one year.
