SikaGrout®-212 HP NZ

Shrinkage compensated high strength cementitious grout

SikaGrout®-212 HP NZ is a cementitious grout containing a carefully formulated blend of aggregates and other materials, plus Sika admixtures, that enables it to achieve high early age and long term strengths. SikaGrout®-212 HP NZ has been designed to incorporate a two stage process that counteracts the effects of shrinkage often associated with cement grouts. Sika Grouts contain materials that provide positive expansion in the plastic phase and shrinkage compensation once hardened. Sika Grouts are normally used in details where the material can be confined and restrained during placement and curing to optimise these characteristics. SikaGrout®-212 HP NZ is a one component grout and only requires mixing with clean, fresh water.

  • High early age strength development
  • Increased resistance to aggressive liquid penetration when hardened
  • Very high final strengths
  • Adjustable consistency
  • High flow characteristics
  • Positive shrinkage compensation

Usage

SikaGrout®-212 HP NZ is ideal for many types of structural grouting applications where high early age and/or long term compressive strengths are required. It can be mixed to different stages of fluidity to produce the desired level of workability. Add the required amount of water for:-
  • Trowel applied medium flow mortar
  • Pourable high flow grout
  Typical applications for SikaGrout®-212 HP NZ are:-
  • Under machine foundations and base plates
  • Reinforcement ducts in the connection detail between precast columns and beams
  • For gaps of 6 mm to 80 mm

Advantages

  • High early age strength development
  • Increased resistance to aggressive liquid penetration when hardened
  • Very high final strengths
  • Adjustable consistency
  • High flow characteristics
  • Positive shrinkage compensation

Application steps

MIXING

Application temp: +5°C to +25°C. Pour the required amount of clean, fresh water into a suitable mixing container and slowly add all of the powder while mixing continuously with a Sika mixing paddle attached to a low speed electric drill (max. 500 rpm). Mix for 2-3 minutes until a smooth, lump free consistency is achieved.

APPLICATION

Flush out detail with clean, fresh water prior to grout placement. Grout should be placed into forms immediately after mixing, taking care to
ensure no air is trapped.

CURING TREATMENT

Formwork should be left in place for at least 5 days if possible, to prevent moisture evaporation and provide restraint to early age hardened expansion. Once formwork is removed a suitable curing membrane such as Sika Antisol® should be applied to any exposed faces. Refer to separate data sheet for further information.

CLEANING OF TOOLS

Clean all tools and equipment with water immediately after use. Hardened SikaGrout®-212 HP NZ can only be removed mechanically.
