Isoxel 5450 - set accelerating admixture
Characteristics
ISOXEL 5450 is a set accelerating admixture based on anorganic salts (free of chloride), which is specially formulated to reduce setting time and increase early strengths of concrete.
Technical data
| Additive | Calciumnitrate/thiocyanate |
| Density (20 °C) | 1,40 ± 0,03 g/cm³ |
| CI-content | ≤ 0,10 M.-% |
| Na2O-equivalent | ≤ 3,00 M.-% |
| Colour and form | Clear liquid |
| Recommended range of dosage | 0,2– 3,0 M.-% by weight of cement |
Effects
- Reduction of setting time
- Increase of early strengths
- Reduction of workability time
- Slight plasticizing effect depending on type of cement
- Optimum dosage: 2,2 M.-% by weight of cement
Application
ISOXEL 5450 is used as an universal set accelerator for all cementitious systems. Important note: Temperatures below < 5°C will stop the hydration process of cement. Therefore suitable curing is essential.
Admission
ISOXEL 5450 is permanently subject to internal factory production control.
Storage
Storage life is 12 months from date of manufacture if stored correctly (tightly closed at > +5 °C):
- Keep storage containers and tanks tightly closed
- Protect product from frost, heat and direct sunlight
Isoxel 899 - hardening accelerating admixture
Characteristics
ISOXEL 899 is a hardening accelerating admixture based on anorganic salts (free of chloride), specially formulated to increase early strengths of concrete.
Technical data
| Additive | Calcium Formate |
| CI-content | ≤ 0,10 M.-% |
| Na2O-equivalent | ≤ 1,50 M.-% |
| Colour and form | Light grey powder |
| Recommended range of dosage | 0,2– 5,0 M.-% by weight of cement |
Effects
- Acceleration of hardening process without reducing the workability period
- Increase of early strengths
Application
ISOXEL 899 is mainly used for applications with high early strengths in concrete and mortar. The use of cement types with a high clinker content and the combination with a high-performance superplasticiser based on PCE support the product performance. Important note: Temperatures below < 5°C will stop the hydration process of cement. A suitable curing process is therefore essential.
Admission
ISOXEL 899 is permanently subject to internal factory production control.
Storage
Storage life is 12 months from date of manufacture if stored correctly (tightly closed at > +5 °C):
- Keep storage containers and tanks tightly closed
- Keep the product away from humidity before using
Developed by CEMEX
CEMEX introduced a proprietary admixtures family called D.fab, which transforms conventional concrete into a versatile material that can be efficiently tailored for 3D printing construction. Read more about the material solution here.
