Product Description:

Superplasticizer  Concrete Admixture Powder and Liquid JF-7


Applications

  • *JF-7 is made up from a mixture of set retarder, stabilizing agent, intensifier and etc.

  • *JF-7 characteristic are efficient water-reducing rate, delayed coagulation, less loss of slump constant, etc.

  • *JF-7 is the best choice for concocting the high-strength concrete.

  • *JF-7 can produce powder, liquid in two forms, to meet the different needs of the project.

Properties


  • *Excellent water-reducing ability. JF-7 can significantly reduce 15% ~25% mixing water in concrete

    with 1.5%~3.0% dosage.

  • *Air content increased slightly, and no adverse effects for concrete strength.

  • *Increase value of fall highness: 10-18cm,1h loss<1/7, 2h loss<1/5,JF-7 is favorable for

    transportation and running castings of commercial concrete.

  • *Setting time delay about 1-3h, and can be adjusted at any time in accordance with the actual requirements.

  • *JF-7 can improve and enhance the each index of concrete, e.g. durability, workability, rupture strength,

    pull resistance, impermeability and etc.

  • *JF-7 applies to concrete work under the condition of 5℃-40℃.

  • *When JF-7 mixed use with other admixture, test must be done to confirm the validity.

  • *When first use this product and change the cement type, it should be according to the actual project.
