Struplast N470
High-range Super Plasticizing Admixture
Struplast N470 is a chloride free, super plasticizing admixture based on specially selected and blended synthetic polymers. It is supplied as a brown solution which instantly disperses in water. Struplast N470 disperses the fine particles in the concrete mix, enabling the water content of the concrete to perform more effectively. The very high levels of water reduction possible allow major increases in strength to be obtained.

- Specifically developed for use in high quality concrete for workability retention at low water content.
- Provides good pumpable concrete
- Recommended for piling and mass concrete pours with improved cohesion.
Advantages
- High range water reducing property allows the production of high quality concrete without excessive cement contents-ensures improved durability.
- Improved cohesion and particle dispersion minimizes segregation and bleeding and improves pumpability.
- Chloride free, safe for use in precast, prestressed and reinforced concrete.
Standards compliance
Struplast N470 conforms with BSEN 934-2, BS 5075 Part 3 and with ASTM C494 as Type A and Type F, depending on dosage used.
Properties
Typical dosage
The optimum dosage of Struplast N470 to meet specific requirements should always be determined by trial mixes using the materials and conditions that will be experienced in use. For normal concrete a dosage between 0.3% to 1.0% by weight of cement may be used.

Instructions for use
- Compatibility: Struplast N470 is compatible with other STRUMIX admixtures in the same concrete mix. All admixtures should be added to the concrete separately and must not be premixed together prior to addition. The performance of concrete containing more than one admixture should be assessed by trial mixes.
- Struplast N470 is suitable for use with all types of Portland cements, SRC cements and cement replacement materials such as PFA, GGBFS and microsilica.
- The use of a combination of admixtures in the same concrete mix and or cement replacements may alter the setting time. Trials should always be conducted to determine such setting times.
Packaging & Storage
- Struplast N470 is available in 20 kg containers, 240 kg drums and 1100 kg IBC tank.
- Struplast N470 has a minimum shelf life of 12 months provided the temperature is kept within the range of 5°C to 35°C. Should the temperature of the product fall outside this range then contact STRUMIX for advice.
- Freezing point: Approximately -2°C
Health and safety
Struplast N470 does not fall into the hazard classifications of current regulations. However, it should not be swallowed or allowed to come into contact with skin and eyes.
