SikaGrout®-212 NZ

High strength, shrinkage compensated, pourable cementitious grout

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

SikaGrout®-212 NZ offers the following advantages:
  • Positive shrinkage compensation
  • High early age strength development
  • High final strengths
  • Excellent substrate adhesion
  • Adjustable consistency
  • High flow characteristics
  • Increased resistance to aggressive liquid penetration when hardened

Usage

SikaGrout®-212 NZ is ideal for many types of structural grouting applications. It can be mixed at different stages of fluidity to produce the desired level of workability. Add the required amount of water for:
  • Rammable dry pack material
  • Trowel applied medium flow mortar
  • Pourable high flow grout
Typical applications for SikaGrout®-212 NZ are:
  • Under machine foundations and base plates
  • For gaps of 6 mm to  80 mm
  • Grouts for anchor bolts, ground anchors, rods, etc.
  • Reinforcement ducts in the connection detail between precast columns and beams.

Application steps

MIXING

  • 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

Application temp: +5°C to +25°C. Grout should be placed into forms immediately after mixing, taking care to ensure no air is trapped.

CURING TREATMENT

Once formwork is removed the use of 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 NZ can only be removed mechanically.
