Air-entraining
PAMIX 12 IA
Air-entraining admixture for concrete
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 12 IA is a liquid admixture based on surfactants, designed to entrain microbubbles uniformly in concrete. Depending on its dosage it complies with ASTM C 260.
Recommended applications
- Concrete structures in contact with water.
- Concrete designed for durability.
- Structures in ports, canals and hydroelectric works
- Concrete for flowable fill.
- Piles, slabs. Tanks, pools.
Advantages
- Helps the watertightness of the concrete
- Minimises seepage problems.
- Reduces bleeding and segregation in plastic concrete.
- Reduces the water required in the mix, complying with ASTM 494 as type A
- Helps the stability of the concrete during transport to the job site.
Dosage
Reference dosage 0.25% to 2% of cementitious material
The recommended dosage is between: 0.25% to 2% of cementitious material; to define the appropriate dosage for use in concrete, consult your trusted advisor at PAMIX INTERNATIONAL, S.A., who will make a suggestion according to the use of the concrete; nevertheless, it is advisable to run trials with all the materials to be used in the concrete mix design, taking into account ambient conditions, transport time and placement time of the concrete on site. It is important to define the dosages of the admixtures involved in the mix design.
The best performance of the admixture in the concrete mix is obtained by evaluating the materials to be used; by keeping to this practice with the guidance of PAMIX INTERNATIONAL, S.A., you will obtain the best cost–benefit ratio.
To minimise the problems that arise when ambient or concrete temperatures are high, follow the recommendations of the current ACI 305R, “Hot Weather Concreting”. Contains no added chlorides. Consult the Safety Data Sheet before use
Compatibility
Pamix 12 IA is effective either as a single admixture or as part of a system with other admixtures in the Pamix line; it is added to the mix independently of other admixtures.
