Sodium Naphthalene Sulfonate Formaldehyde Introduction:

Sodium Naphthalene Sulphonate water-reducing agent is a synthetic powder formulated from β-sulphonate formaldehyde condensate and reactive polymers. It features high-range water reduction, set-retarding properties, and excellent strength-enhancing performance. With a sodium sulfate content of less than 10%, it is ideal for medium-to-high strength concrete requiring significant water reduction.

Sodium Naphthalene Sulfonate Formaldehyde Usage Instructions:

2.1 Dosage

      Blending dosage: 0.5%–1.0% (by weight of cement), with a recommended dosage of 0.6%.

      Adjust dosage based on specific mix design and performance requirements.

2.2 Solution Preparation

       Prepare aqueous solutions as needed, following standard mixing procedures for concrete admixtures.

2.3 Application Methods

      The powder agent can be used directly.

      Alternatively, add the agent to the mix followed by water addition, maintaining a water-to-cement ratio of 60% (or as specified in  

      the mix design).

Sodium Naphthalene Sulfonate Formaldehyde Applications:

4.1 Curing Processes

      Widely used in self-cured and vapor-cured concrete formulations, it demonstrates outstanding early-stage performance. This 

     significantly improves modulus and site utilization efficiency, even eliminating the need for vapor curing during peak summer heat. 

     Statistically, 40–60 metric tons of coal can be saved per metric ton of this agent consumed.

4.2 Concrete Formulations

      Suitable for preparing early-strength, high-strength, high anti-filtration, self-sealing, and pumpable concrete.

4.3 Construction Scenarios

      Extensively applied in pre-cast and ready-mixed concrete, reinforced concrete, and pre-stressed reinforced concrete for key 

      projects, including:

     Dam and port construction

     Road building and urban planning projects

     Residential and commercial constructions

4.4 Cement Compatibility

A.Compatible with various cement types, such as:

    Portland cement

    Ordinary Portland cement

    Portland slag cement

    Fly-ash cement

    Portland pozzolanic cement

B.Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.

C.Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key    

     construction projects such as dam and port construction, road building & town planning projects and dwelling  

     erections etc.

D.Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland

    pozzolanic cement etc.
