ZM-HNJS

  • ZH-HNJS type compound type cement, concrete set retarder. This product has a significant set retarding effect to various types of cement and concrete, it is widely used in all kinds of concrete projects, admixture and cement plants that require set retarding. This product is non-toxic, non-flammable and harmless to human health. This product executes the standards of GB8076-2008 (Concrete admixtures), GB50119-2013 (Technical specification for application of concrete admixture), GB/T8077 (Methods for testing uniformity of concrete admixture).

    1. It has a good adaptability to various types of cement.
    2. It has resistance to high temperature; drying at temperatures lower than 200°C for 2 hours does not affect other performance indices.
    3. It has significant set retarding effect on cement and concrete. Testing at standard temperatures 20°C ± 3 can retard the setting time of the cement paste for 4-8 hours compared with the reference sample, and it retards the setting time of the concrete for 6-24 hours compared with the reference concrete. High dosage, long set retarding time, the optimal dosage is determined by the test.
  • According to the product performance indices and user requirements, it meets the national, industrial and corporate standards.

  • This product is suitable for the production of slow setting cement, set retarding concrete and with various kinds of pumping admixtures.

    1. The dosage range of this product is 0.2-0.5% (calculated based on the amount of cementitious materials), the optimal dosage is determined according to the test.
    2. In the production of slow setting cement, when the basic materials of cement are added into the ball mill, spray atomization method is used to add it based on dosage into the cement production process.
    3. Directly incorporate into the concrete or compound admixtures, according to climate change, and the requirements of set retarding time, the optimal dosage is adjusted and determined according to the test.
    1. Prior to use, the setting time with cement or concrete should be checked according to the mix ratio.
    2. Accurate dosage must be made according to the requirements.
    3. In the production of slow setting cement, spray atomization method is used to add the materials evenly.
    4. It should be used with caution when the daily minimum temperature is below 5℃; If there is freezing in a negative temperature environment, when it is used after thawed, the effect will not be affected.
    1. It can be transported by closed tankers; Iron barrel 200kg/barrel, plastic barrel 1000kg/barrel; it can also be specially packaged according to user requirements.
    2. This product has a one-year warranty, if there is precipitation during the warranty period, it is recommended to mix evenly before use, and it does not affect the effect.
