Duconmix RSP 600 – High-Performance Retarding Superplasticizer in Bangladesh

Duconmix RSP 600 is an advanced slump retention admixture designing to enhance the workability and durability of concrete in high-temperature conditions. As a premium retarding superplasticizer in Bangladesh, it effectively delays initial setting time while maintaining excellent slump retention, making it ideal for large-scale construction projects, ready-mix concrete, and long-distance concrete transportation. This retarding admixture optimizes concrete flow, improves strength development, and reduces water-cement ratios, ensuring superior performance in challenging environments. Whether you need a slump retention admixture in Bangladesh for high-rise buildings, bridges, or infrastructure projects, Duconmix RSP 600 delivers exceptional consistency and quality. Choose Duconmix RSP 600 for reliable retarding superplasticizer solutions.

Concrete Admixture retarding superplasticizer Bangladesh retarding superplasticizer

Ducon’s Duconmix RSP 600 is a Retarding Superplasticizer Concrete Admixture. It is formulated of synthetic polymers (sulfonated naphthalene and Sodium Lignosulfonate), specially designing to modify the Rheoplastic qualities of concrete. Our product shall have an average relative density of 1.23 at 25ºC.

The retarding superplasticizing admixture for concrete shall be Ducon Mix RSP 600, a sulfonated naphthalene and Sodium Lignosulfonate polymer-base formulation having slump-retaining capabilities. It complies with IS 9103 and type G when tested to ASTM C-494.

Duconmix RSP 600 Recommended Uses:

  • Ready-mixed concrete (RMC)
  • Long hauls and two- to three-hour slump retention concrete.
  • Pumped concrete
  • Concrete containing Granulated Slag or Pozzolans
  • Concrete needs to be transported long distances.
  • Hot weather concreting. 

Features and Benefits of Duconmix RSP 600: 

  • Reducing thermal peaks
  • High workability for longer periods
  • Lower pumping pressure
  • Resistance to segregation even at high workability
  • Extending setting with longer workability
  • Reducing water content for a given workability
  • Higher ultimate strengths
  • Reducing permeability
  • Improving durability
  • Reducing shrinkage and Hair crack
  • Increasing ease in finishing concrete
  • Provides lower in-place cost.

Ducon’s Duconmix RSP 600 is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 50 to 70% of the mixing water has been added. The addition of Duconmix RSP 600 to dry aggregate or cement is not recommended. Automatic dispensers are available.

COMPATIBILITY: 
Duconmix RSP 600  is compatible with most admixtures used in the production of quality concrete, including normal, other mid-range and high-range water-reducing admixtures, air entrainers, accelerators, retarders. It’s extending set control admixtures, corrosion inhibitors, and shrinkage reducers. Duconmix RSP 600 is compatible with slag, fly ash, kaolin, and silica fume.

DOSAGE

The optimum Duconmix RSP 600 dosage should be determined with trial mixes. As a guide, a dosage range of 200 mL to 600 mL per 50 kg / 1 Bag of cementitious material is recommended as a starting point. In high performance concrete a dosage upto 900ml per 50kg or 1 bag of cementitious material can be added subject to prior site trials. Because of variations in concrete materials, job site conditions, and/or applications, dosages outside of the recommended range may be required. In such cases, contact your local Ducon representative. For additional information on Duconmix RSP 600 admixture or on its use in developing concrete mixes with special performance characteristics, contact your local Ducon representative. Effects of over dosage

DOSAGE and OVER DOSAGE

A severe overdosage of Duconmix RSP 600 can result in the following:

  • Long extension of the initial and final setting.Increase in air entrainment
  • Bleeding or segregation of mix, quick loss of workability
  • Increasing plastic shrinkage.

A slight overdose may not adversely affect the ultimate strength of the concrete and can achieve higher strengths than normal concrete, providing properly compacted and cured. Due allowance should be made for the effect of fluid concrete pressure on formwork, and stripping times should be monitored. In the event of overdosage, consult your local Ducon representative immediately.
