SikaGrout®-212

General Purpose cementitious grout

SikaGrout®-212 is a one-component, ready to mix, free flowing, non-shrink, cementitious grout with a unique 2-stage shrinkage compensating mechanism.

  • Easy to use (ready to mix powder)
  • Shrinkage compensated properties in both the plastic and hardened states
  • Multiple fluidity with a single component
  • Good bond to concrete
  • Non-metallic, will not stain or rust
  • Contains no chloride
  • Blend of shrinkage-reducing and plasticizing/water-reducing agents
  • Low heat build-up
  • Excellent for pumping: does not segregate, even at high flow. No build-up on equipment hopper
  • Superior freeze/thaw resistance
  • Resistant to oil and water

Application steps

MIXING

  • Pour the water in the recommended proportion into a suitable mixing container.
  • While mixing slowly, add the powder to the water.
  • Mix thoroughly for 3 minutes with low speed (< 500 rpm) hand drill mixer to avoid entraining too much air and until homogenous with no lumps.

             

EXTENSION WITH AGGREGATES

           

  • For deeper applications (plastic and flowable consistancy only), 25 lbs. of 3/8" (9.5 mm) coarse aggregate can be added.
  • The aggregate must be non-reactive (reference ASTM C-1260, C-227 and C-289), clean, well graded, saturated surface dry, have low absorption and high density, and comply with ASTM C-33 size number 8 per Table 2.
  • Variances in aggregate may result in different strengths.
  • Add pea gravel after the water and SikaGrout®-212.

APPLICATION

  • Within 15 minutes after mixing, place grout into forms in normal manner to avoid air entrapment.
  • Vibrate, pump, or ram grout as necessary to achieve flow or compaction. SikaGrout®-212 must be confined in either the horizontal or vertical direction leaving minimum exposed surface.
  • SikaGrout®-212 is an excellent grout for pumping, even at high flow.
  • For pump recommendations, contact Technical Service.
  • After grout has achieved final set, remove forms, trim or shape exposed grout shoulders to designed profile.

CURING TREATMENT

Wet cure for a minimum of 3 days or apply a curing compound which complies with ASTM C-309 on exposed surfaces.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use.
