Product Description:

Naphtalene Superplasticizer China Raw Materials Additives for Concret 

Description

1. Appearance:Light brown powder &dark brown liquid. Non-poisonous,odorless, non-flammable and non-corrossive

to steel bars.

2.Remarkable Plasticity:As a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing

 water can be decreased by 16-22%when it is admixed with reinforced concrete at 0.5-1.0%. Statistically, compression

 strength on the 1st day, the 3rd day and the28th day after singleapplication is increased by 60-95% and 25-40%

 respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength,buckling

strength and modulus of elasticity will be improved to some extent.

3.Improve miscibility of concrete amalgamator with water and cillapsibilityas well. As a conditionof equivalent blending,

collapsibility can be increased 4-6 times when it is added at 0.75% blend dosage.

4.15-18% of cement can be reserved when the agent is blended at 0.75% blend dosage,which is preconditioned by same

 collapsibility and strength.


Applications

1. NSF is suitable to make high flowing concrete, commercial concrete, pumping concrete, precast and reinforced concrete.

2. NSF can be used to make C10-C60 concrete with slump loss between 50mm and 70mm, or C60 concrete with slump between 180mm and 220mm

3. NSF can be used as raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.

4. NSF is compatible with Portland Cement, Portland Slag cement, Fly-ash Cement, Portland Pozzolanic Cement etc.

Features and Benefits

Non-toxic, non-irritating and no corrosion to steel bars

High water reducing rate: up to 25%

Strengthening ability

Improving concrete durability and impermeability

Appropriate setting time

Dosage and Usage

1. The dosage is about 0.5 ~ 1.5% of cementitious materials, actual usage needs to be confirmed by the test. 

2. Due to the adaptive differences between different types of the cement and admixtures. The adaptive test of cement and

admixture should be done before using or changing the cement type.

Packaging, transport and storage 

1. The powder product is packed with 25 ± 0.25kg laminating woven bag. Packaging specifications should meet the user

requirements. 

2. Powder product is easy to soluble in water, liquid dilution will affect the effective concentration of the product, transport and

storage should be noted that the anti-leaching, avoid moisture, direct sunlight, kept under seal and away from open flame at the

room temperature or during the transport.

3. In the case of good storage conditions, valid period is three years. If it is more than 3 years, rechecking is needed for using

continually.
