Plasticizing additive for ready-mix concrete of normal consistency

Sika® Plastiment®-540 BV is a plasticizing / water-reducing additive for concrete with universal applicability, used for obtaining ready-mix concrete of normal consistency.

Usage

The plasticizing additive Sika® Plastiment®-540 BV shall be used for the following types of concrete:

  • Ready-mix concrete of normal consistency,
  • Waterproof concrete,
  • Pumpable concrete,
  • Exposed concrete,
  • Road concrete,
  • Mass concrete.
Advantages

Mixed into the concrete mass, Sika® Plastiment®-540 BV has the effect of:

  • Better dispersion and hydration of the cement
  • Lower friction forces between cement and aggregates
  • Reducing the amount of mixing water

Thus the resulting concrete has the following properties:

  • Improved workability at the same W/C ratio
  • Water reduction at the same workability
  • Homogeneous concrete with minimized segregation tendencies
  • Increased strengths
  • Concrete with increased density
  • Reduced shrinkage and creep
  • Increased durability
  • Visibly improved surfaces
  • Lower production and placing costs

Application

Compatibility

The Sika® Plastiment®-540 BV additive is compatible with all cementitious materials meeting the requirements of EN 197-1. The Sika® Plastiment®-540 BV additive is compatible within the concrete mass with set-accelerating, set-retarding, air-entraining, waterproofing and shrinkage-reducing additives from the Sika product range.

Recommended dosage

The Sika® Plastiment®-540 BV product shall be dosed between 0.2 – 1.2% of cement mass.

APPLICATION INSTRUCTIONS

Sika® Plastiment®-540 BV is dosed at the plant, together with the mixing water, or towards the end of mixing. It is recommended to avoid dosing the additive over the dry mix. The mixing time will be adjusted depending on the type and power of the mixer. It is recommended to maintain a mixing time of min. 45 seconds.

To avoid the use of excess water, it is recommended to make water corrections at 2/3 of the mixing time. In case of overdosing, in addition to the effect of increasing workability, the concrete setting may be affected, without however affecting the final strengths of the concrete.
