Application

1.      Naphthalene Sulphonate (FDN) concrete admixture is suitable to make autotrophic concrete, steam curing concrete, steel concrete and prestress concrete, all of which are made mainly of portland cement. When concrete added this superplasticizer needs to be steam cured, it requires considerable structural strength. The curing requirements should be pre-tested.

2.      Naphthalene Sulphonate (FDN) concrete admixture is applicable in areas with the daily lowest temperature of 0 Celsius Degree and for making concrete which requires high fluidity, high strength or steam curing.

3.      Naphthalene Sulphonate (FDN ) concrete admixture can be used to make C*0 concrete with slump loss between *0mm and *0mm, or C*0 concrete with that between **0mm and **0mm.

4.      Naphthalene Sulphonate (FDN ) concrete admixture could be used as a raw material together with other components to make other kinds of admixtures, such as accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.

5. Naphthalene Sulphonate (FDN) concrete admixture will also fluidize concrete, making it ideal for tremie concreting or other applications where high slumps are desired.

6. Naphthalene Sulphonate (FDN) concrete admixture is compatible with Portland Cement, Portland Slag Cement, Fly-ash Cement, Portland Pozzolanic Cement, etc.

Uses and Dosages

1. It can be added directly or added in after being dissolved. It can be added during mixing and after-mixing.

2. The afterward approach can achieve better result. It's addition rate ranges from 0.4% to 1.0% of the weight of cementitious material in 1m3 of concrete, while the suggested rate is 0.5%.

3. If it is used in powder form, add it directly into cement, but not onto wet sand and gravels. If solution is used, please fully stir and dissolve it completely.

Raw material for production

1. Crude Naphthalene (*8%)

 2. Sulphuric Acid (concentration *8%)

 3. Formaldehyde (concentration *6%)

 4. NaOH(****0%)
