Uniplast AE121
Air Entraining Concrete Admixture
PRODUCT DESCRIPTION
UNIPLAST AE121 is a chloride free air-entraining admixture based on selected sugar reduced lignosulphonates and surface-active agents which is easily dispersed in water.
UNIPLAST AE121 entrains 4%-6% by volume.
UNIPLAST AE121 acts at the interface between the mixing water and cement/aggregate particles to produce microscopic air bubbles, which are evenly distributed throughout the concrete. The entrained air enhances durability by providing protection against the rapid temperature changes found in freezing and thawing conditions and with the use of de-icing salts.
STANDARD COMPLIANCE
UNIPLAST AE121 complies with CYS EN934-2:2009 +A1:2012 Table 5 - Specific requirements for air entraining admixtures (at equal consistence).
UNIPLAST AE121 is certified by CERTIF (Certification Organization) with the Certificate of the Factory Production Control with Certificate Number 1328 - CPR - 0063 and bears CE marking.
PROPERTIES
Appearance: Liquid
Colour: Brown
Specific Gravity: 1,17± 0,01 at 20°C
pH: 6,75 ± 1,0 at 20°C
Chloride Content: Chloride Free
DOSAGE
Trials should be carried out with the proposed concrete mix in order to determine the optimum dosage of UNIPLAST AE121. Higher dosages may be used under adequate supervision.
UNIPLAST AE121 is compatible with all types of cement which are produced in Cyprus. It can also be combined with all other Concrete Admixtures manufactured by our company. Suggested starting point dosages are 0.13 to 0.30 litres / 50 kg of cement.
MAIN USES
- To produce air entrained concrete for increased durability and resistance to damage by frost and de-icing salts. Typical applications include concrete roads and bridge decks, airport runways and taxiways and other extensive areas of concrete exposed to potential frost damage.
- To improve cohesion and workability of concrete mixes where poorly graded aggregates must be used and bleeding, segregation or sand runs occur.
- To reduce permeability of lean concrete mixes.
- To improve stability and cohesion in extruded concrete.
ADVANTAGES
- Chloride free, safe to be used in reinforced and prestressed concrete.
- Entrained air bubbles assist in the formation of a stable cohesive mix, reducing segregation and bleeding.
- Air entrainment increases the resistance of concrete to attack by frost and de-icing salts, reducing problems of surface scaling and concrete failure.
- Air entrainment improves workability and helps produce a dense, uniform, close textured surface free from gravel nests and sand runs, further enhancing durability.
- Water reduction allows concrete to be produced with reduced permeability and increased strength compared to that obtained with air entrainment alone.
