Uniplast C09

Set Retarding / Water Reducing / Plasticising Concrete Admixture

PRODUCT DESCRIPTION

UNIPLAST C09 is a blend of lignosulphonates and other inorganic and organic chemicals and is supplied as a brown liquid with a specific gravity of 1.205 at 20 °C, which is easily dispersed in water.

UNIPLAST C09 is free of chlorides and entrains less than 2% of additional air to concrete at normal dosages.

UNIPLAST C09 disperses the fine particles of cement in the concrete mix, enabling the water content to perform more effectively thus improving concrete consistency and increased workability. The initial hydration of the cement is delayed, resulting in a delay in the setting time of the concrete with no negative effect on subsequent stiffening and strength gain.

STANDARD COMPLIANCE

UNIPLAST C09 complies with CYS EN934-2:2009 + A1:2012 Table 10 – "Specific requirements for set retarding /water reducing /plasticizing admixtures (at equal consistence)". UNIPLAST C09 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: 1,205± 0,01 at 20oC
pH: 6,75 ± 1,0
Chloride Content: Chloride Free

DOSAGE

Trials should be carried out with the proposed concrete mix in order to determine the optimum dosage of UNIPLAST C09.

Suggested starting point dosages are 0.10 to 0.35 litres / 50 kg of cement. Higher dosages may be used under adequate supervision and will impart superpalsticising properties and extended workability.

UNIPLAST C09 is compatible with all types of cement which are produced in Cyprus and performs extremely well with microsilica. It can also be combined with all other Concrete Admixtures manufactured by our company

The level of retardation obtained may be varied by altering the dosage of UNIPLAST CO9 used, which will also alter the lever of water reduction obtained.

Retardation is also affected by factors other than the admixture, depending on the mix design and conditions involved. High temperatures will require increased dosages.

MAIN USES

  • To reduce the w/c ratio of a concrete mix and to improve workability.
  • To improve set retardation of concrete in high temperatures.
  • To extend working time.
  • To help maintain the workability of ready mixed concrete deliveries in hot weather.
  • To increase early compressive strengths.

ADVANTAGES

  • Chloride free, safe to be used in reinforced and prestressed concrete.
  • Specified strength grades can be achieved at reduced cement content.
  • Reduces concrete permeability and limits water absorption, thus enhancing concrete durability.
  • Achieved water reduction improves significantly compressive strengths at all ages.
  • Allows workability to be increased without adding extra water, thereby maintaining strength levels.
  • Minimised transportation delay problems maintain placeability and reduces the risk of pump blockage
