Sikacrete®-211 SCC Plus

Sikacrete®-211 SCC Plus

One-component, cementitious, polymer-modified, self consolidating concrete mix with an integral migrating corrosion inhibitor

Sikacrete®-211 SCC Plus is a one-component, self consolidating concrete containing factory blended coarse aggregate. This self consolidating concrete bag is silica fume and polymer modified and also contains a migrating corrosion inhibitor.

  • Self Consolidating Concrete - Excellent placement characteristics
  • Polymer-modified
  • Integral penetrating corrosion inhibitor
  • Silica fume enhanced
  • Prepackaged coarse aggregate. Eliminates the need to extend material in the field. Eliminates the risk of reactive aggregate
  • Can be pumped or poured into forms and gets excellent consolidation without vibrating

Pot Life

~ 60 minutes

As the temperature will affect the pot life, application temperature:

  • Above 73 °F (23 °C) will reduce the pot life and slump

  • Below 73 °F (23 °C) will extend the pot life and slump

Application steps

MIXING

  • Start mixing with 5.5 pints (2.6 L) of water.
  • An additional 0.5 pint (0.2 L) can be added if needed.
  • Do not over water as excess water will cause segregation.
  • Add Sikacrete®-211 SCC Plus while continuing to mix.
  • Mechanically mix to a uniform consistency, for 3 minutes with a low-speed drill (400–600 rpm) and paddle or in appropriate-size mortar mixer or concrete mixer.

APPLICATION

  • Pre-wet surface to SSD.
  • Ensure good intimate contact with the substrate is achieved. To accomplish this, material should be scrubbed into the substrate or other suitable means should be employed such as vibration of the material or pumping under pressure.
  • Tap form lightly while pouring or pumping, do not vibrate.
  • Pump with a variable pressure pump.
  • Continue pumping until a 3 to 5 psi increase in normal line pressure is evident then STOP pumping.
  • Form should not deflect.
  • Vent to be capped when steady flow is evident, and forms stripped when appropriate.

CURING TREATMENT

  • As per ACI recommendations for Portland cement concrete, curing is required.
  • Moist cure with wet burlap and polyethylene, a fine mist of water or Sika® Antisol®-250 W*.
  • Curing compounds adversely affect the adhesion of following layers of mortar, leveling mortar or protective coatings.
  • Moist curing should commence immediately after finishing.
  • Protect newly applied material from direct sunlight, wind, rain and frost.


* Pretesting of curing compound is recommended.
