Sikacrete® Self Consolidating Concrete

One-component, cementitious, polymer-modified, self consolidating concrete mix

Sikacrete® Self Consolidating Concrete 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

Application steps

MIXING

Start mixing with 4.2 pints (2 L) of water. An additional 0.3 pint (0.15 L) can be added if needed. Do not over water as excess water will cause segregation. Add Sikacrete® Self Consolidating Concrete while continuing to mix. Mix to a uniform consistency, maximum 3 minutes. Mechanically mix 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 (Saturated Surface Dry). 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. Vibrate form while pouring or pumping. 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.

  

Tooling and Finishing

As per ACI recommendations for portland cement concrete, curing is required. Moist cure with wet burlap and polyethylene, a fine mist of water or a water based* compatible curing compound. 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.
