DESCRIPTION

ASD-5 is a low concentration superplasticizerbased on Sodium naphthalene sulphonate formaldehyde, which is purified non leadgas product, the product is low sodium sulfate, low alkali, yellowish brownpowder, which has been formulated to comply with the requirements of GB8076-2008,GB8077-2000 in China. ASD-5 is compatible with the requirements of EN934-2(Table 3.1 and 3.2) and ASTM C 494 for Type F high range water reducing admixtures.ASD-5 is accordant with all cements meeting recognized international standards.

 

KEY BENEFITS

1. The product has a significantly reducedwater dispersion effect, the low dosage has >14% water reducing rate, the high dosage has >20% water reducing rate. Theproduct can improve the fluidity of cement paste in the case of low watercement ratio.

2. In the same water cement ratio, theproduct can greatly improve the concrete workability; the initial concreteslump can improve more than 250px.

3. The products have a strong remarkableeffect in early stage. In the appropriate dosage, the concrete can improve thestrength of 50%-70% in 3 days, 40%-60% in 7 days, 25%-30% in 28 days; thegrowth of the strength will be maintained in the future.

4. In the same condition of originalstrength of the concrete and same slump, the product can save cement usageamount about 20%.

5. The product does not lead gas, has noeffect on the setting time of concrete, has a wide range of adaptability on variouscement, improve the strength, compaction, waterproof, wear resistance ofconcrete.

 

TYPICAL APPLICATIONS

1. The product has a wide range ofadaptability on various cement, the product widely used in highly flow ableconcrete, high strength concrete, high performance concrete, highimpermeability concrete, ready-mixed concrete, self compacting concrete, massconcrete, pumped concrete, wet sprayed concrete, prestressed reinforcedconcrete.

2. The product is suitable for preparationof C60 concrete, and all kinds of industrial and civil construction, waterconservancy, transportation, port, municipal and other projects.

3. The product is especially suitable for centrifugalsteamcuring concrete products.

4. The product is applied to the nationalkey construction projects, such as large reservoirs, large bridges, highbuildings and so on.

APPLICATION GUIDELINE

1. Dosage: recommended ASD-5 dosage rangeis 0.5%-1.5% of cement usage amount. Commonly dosage range is 0.75%-1.0% ofcement usage amount. Dosage according to the quality of the cement and cementgrade, the lower cement grade needs more ASD-5 dosage.

2. Trial concrete mixes must be carried outto determine the appropriate usage to meet concrete mix design requirement. Theuse of excess amount also can improve the concrete workability, but it willaffect the setting time of concrete. When replacing cement brand, it need test concreteto adjust ASD-5 dosage for mix design requirement.

3. The product can be first dissolved inwater as admixture to use. The product can be used directly into mixingconcrete with water. The concrete mix time need more 30 seconds. The productcan be joined delaying the mixing water 15-20 seconds in the mixing process; theeffect of concrete is remarkable.

4. In the construction process, immediatelycover and water the concrete after the concrete setting, prevent the concretesurface cracking or freezing in winter.

 

PACKAGING ANDSTORAGE

1. The product is supplied in 25 kg.Plastic woven bag with lined thick plastic bags is two layer, sturdy andwaterproof. Packaging size may vary subject to meet customer requirements,but it need pre-order.

2. The product should be stored in dry warehouse, damp proof.If the powder becomes lumps because of moisture, it still can be used after smashing,the effect is same. The shelf lifeis 1 years. If the product is overdue, it can be used after testing qualify.
