PAMIX 802

Description

Pamix 802 is an amber aqueous-solution admixture formulated to modify cement hydration in concrete; depending on its dosage it complies with ASTM C494 as type A, F and ASTM 1017 Type I.

Recommended applications

• High-flow concrete with slump retention.
• Pumpable and general-purpose concrete.
• Watertight, high-durability concrete.
• Concrete for slabs and/or pavements.
• Precast concrete.
• Concrete batched and placed on site.

Advantages

• Produces “flowing” concrete with a controlled range of slump loss and workability.
• Greatly reduces water demand.
• Reduces segregation and bleeding in plastic concrete.
• Reduces cracking and permeability in hardened concrete.
• Significantly reduces placement time and cost.
• Higher compressive and flexural strengths at short, medium and long term, with adequate early-age strength
• Eases finishing and pumping of the concrete.

Dosage

Reference dosage 1 to 15 ml /1 kg of cementitious material

The recommended dosage is between: 1 to 15 ml /1 kg of cementitious material; to define the appropriate dosage, consult your trusted advisor at PAMIX INTERNATIONAL, S.A., who will advise you 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 802 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 and it is not compatible with naphthalene-based admixtures

Packaging

Pamix 802 is supplied in bulk, in 208 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.
