PAMIX 502
Waterproofing and water-reducing 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 502 is a brown aqueous-solution admixture formulated to reduce the permeability of concrete.
Recommended applications
- Concrete structures in contact with water.
- Structures in ports, canals and hydroelectric works.
- Piles, slabs, pools, tanks.
- Concrete designed for durability.
Advantages
- Produces watertight concrete.
- Minimises seepage problems.
- Reduces segregation and bleeding in plastic concrete.
- Reduces the water required in the mix, complying with ASTM C 494 as type A.
- Eases finishing and pumping of the concrete.
Dosage
Reference dosage 0.5 to 2% per 1 kg of cementitious material
The recommended dosage is between: 0.5 to 2% per 1 kg 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.
The best performance of the admixture in the concrete mix is obtained through trials with 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 502 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. It is not compatible with naphthalene-based admixtures.
Packaging
Pamix 502 is supplied in bulk, in 200 L drums and in 1000 litre containers.
The admixture should be kept closed and sealed at all times in its original containers, in a roofed store protected from the weather.
Shelf life
12 months in the original unopened container.
