一   Product Performance characteristics

1、The main ingredient of this product is β -naphthalene sulfonate  formaldehyde condensate，we have liquid and solid,solid is  brown powder,solid is dark brown.No toxic、odorless 、non flammable No corrosion,sodium sulfate content less than 20%

2、the water reducing of this product can reach from 14-28%,can obviously improve the concrete every stage strength、physical performance,especially for early strength,also can improve last strength,its compression﹑tensile﹑anti-braking and elastic modulus.at same condition, it can save cement by 10-20%

3、can obviously improve the cement materials workability ,especially for early strength.

4、increase the concrete durability. Suitable alkali content can improve the concrete anti-permeability and anti-freezing.

5、this product has good adaptability for portland cement、common portland cement、slag cement and fly ash cement

6、can get better performance for water reducing and slump retention by mixing with  aliphatic water reducing admixture and aminosulfonate admixture

二   Using area

1、suitable to produce the precast and on-site concrete﹑ferroconcrete ﹑prestressed concrete under 80 C of the industrial and civil construction ﹑water conservancy﹑port﹑mayor project

2、suitable to produce pumping concrete、high fluidity concrete、self-leveling concrete and steamed concrete.especially for pipe pile and shield segment concrete project.

3、suitable for the long-lasting﹑long-stable large reservoir﹑large bridge﹑high level building of nation key projections

三   Recommended dosage

Normal dosage is 0.5-1.2%,suitable dosage is 0.75%, customers can choice the best dosage by concrete test according to the adaptability of admixture and cement.our factory can supply the technical data of dosage and match ratio as reference freely.

四   packing

1、powder product can be packed by woven bag with plastic liner and moisture proof paper bag of 25kg、40kg、1000kg;liquid can be loaded into plastic barrel、iron drum; and also can be with 20MT flexibag

2、rain proof and moisture proof while transportation,anti-caking. To be sealed when used iron drum for preventing leaking

五   Storage and validity

    Powder should be stored in dry and ventilated warehouse.if caking because of moisture, only can be used after crashed into demanded fineness or solvent into to liquid.if overdue, must be used only after test.

The validity is for 2 years.

六   Using method

1、liquid can be used directly. Put into mixer with cementing material、water ,then stirring.

2、powder will be made to demanded concentration solution first, then use. Also can be added directly, but must more time for stirring.

3、if mixing with other admixture,must have suitability test first.

七   attention

1、if first time to use this product or cementing material changed, have to make concrete test to get the best dosage again.

2、When use liquid, must less the water inside of it for total amount.

八   safety
