Mineral admixture
PAMIX 90 SF
Silica fume mineral admixture
Translated from the Spanish data sheet. Standard designations, ASTM type numbers, figures and units are reproduced unchanged; in case of doubt the Spanish PDF governs.
Description
Pamix 90SF is a dry, densified silica fume mineral blend formulated to produce high-performance concrete. It improves the properties of the concrete chemically and, being ultrafine, fills the voids between cement particles, reducing the permeability of the concrete and increasing its strength Pamix 90SF meets the requirements of ASTM C1240.
Recommended applications
Pamix 90SF is especially recommended in concrete or mortar where the following is required:
- Concrete with high mechanical strength.
- High-density concrete.
- High-durability concrete.
- Concrete in marine environments.
- Piling.
- Foundations.
- Water treatment plants.
- Parking deck.
Advantages
The use of Pamix 90SF brings major advantages to concrete:
- Improves finishing characteristics
- Increases cohesion and compaction, making the placement of pumped concrete easier.
- Improves the stability of the concrete, preventing segregation
- Reduces the rebound of sprayed concrete or mortar, so that thicker layers can be applied.
- Increases the bond of the concrete to the reinforcing steel.
- Gives the concrete greater chemical and mechanical strength
- Increases both early and final compressive and flexural strength.
- Reduces the permeability of the concrete through increased compactness and density.
- Increases durability
- Contains no chlorides.

Dosage
Reference dosage 5% and 15% by weight of cement
The dosage of Pamix 90SF is normally between 5% and 15% by weight of cement.
Preliminary trials are recommended to determine the mix design and the appropriate proportions of all the concrete components according to the requirements.
Application
Pamix 90SF comes ready to use. To obtain the appropriate design consistency, the use of high-range water-reducing admixtures from the Pamix line is recommended.
