MasterEmaco S 466CI Flowable structural-repair concrete with integral corrosion inhibitor

Formerly: S66 CI

 

How does MasterEmaco S 466CI work?

MasterEmaco S 466CI is a flowable, shrinkage-compensated repair concrete. It is designed for large volume repairs, including structural elements in applications from 1" (50 mm) to full depth. It has a unique formulation that provides excellent bond, resistance to sulfates and chlorides, high electrical resistivity, low permeability, high-compressive strengths, and protection from corrosion.

Recommended uses:

  • Interior and exterior
  • Large volume structural repairs
  • Repair or replacement of concrete elements

What are the unique features of MasterEmaco S 466CI?

  • Very low chloride permeability and an integral corrosion inhibitor protects reinforcing steel
  • Only requires the addition of potable water
  • High compressive strength
  • Abrasion resistant for repairs requiring protection from vehicular traffic

What are the benefits of MasterEmaco S 466CI?

  • Excellent freeze/thaw resistance for durability in cold, wet environments
  • Flowability makes it ideal for placement by pumping or pouring into congested locations
  • Shrinkage-compensated, minimizing cracking from drying shrinkage reducing stress at the bond line

Applications

  • Interior and exterior
  • Large volume structural repairs
  • Repair or replacement of concrete elements

Substrates

  • Concrete 

HOW TO APPLY


SURFACE PREPARATION

Concrete

  1. Substrate must be structurally sound and fully cured (28 days).
  2. Saw cut the perimeter of the area being repaired into a square with a minimum depth of 1" (25 mm).
  3. Refer to current ICRI Guideline no. 310.2R for surface prep requirements to permit proper bond.

Reinforcing Steel

  1. Remove all oxidation and scale from the exposed reinforcing steel in accordance with ICRI Technical Guideline No. 310.1R.
  2. For additional protection from future corrosion, coat the prepared reinforcing steel with MasterProtect P 8100 AP.

MIXING

  1. Precondition material to 70° F ±5° (21° C ±3°) before mixing.
  2. Add 0.40–0.60 gallons (1.5–2.3 L) of potable water for each 55 lb (25 kg) bag of MasterEmaco S 466CI. Mix mechanically using a slow-speed drill (400–600 rpm) and a Jiffy paddle or mix in an appropriately sized mortar mixer.
  3. Pour approximately 90% of the mix water into the mixing container, and then charge the mixer with the MasterEmaco S 466CI. Add the remaining mix water as required to obtain desired consistency. Add enough water to the mixing container to obtain a slump of 4–6" (102–152 mm), approximately 0.6 gallons (2.3 L) per bag. Maximum recommended slump is 7" (175 mm).
  4. Mix until a homogeneous consistency is achieved, approximately 3–5 minutes. Do not mix longer than 5 minutes.
  5. For applications greater than 8" (203 mm), add up to 25 lbs (11.3 kg) of 1/2–3/4" rounded, highdensity, washed, SSD coarse aggregate for each 55 lbs (25 kg) of MasterEmaco S 466CI.
  6. Aggregate must comply with the requirements of ASTM C 33.

APPLICATION

Formed Applications

  1. Build forms in accordance with ACI 347R. Keep the unrestrained surface area of the repair to a minimum.
  2. Saturate the prepared concrete substrate by filling the prepared formwork with clean water 24 hours before placement.
  3. Immediately before the placement of MasterEmaco S 466CI, completely drain this water and seal the drainage outlets, leaving the substrate saturated surface-dry (SSD) with no ponded water remaining.
  4. In jobsite circumstances where the formwork cannot be filled with water to achieve an SSD surface, the prepared concrete substrates must be thoroughly hosed down with clean water to achieve an equal level of saturation. Apply the repair material with sufficient pressure to ensure intimate contact with the substrate.
  5. A long open-time bonding agent such as MasterEmaco P 124 may be used in place of a saturated substrate. In such a case, place the MasterEmaco S 466CI before the bonding agent becomes tack free.
  6. Immediately after mixing, pump or pour the MasterEmaco S 466CI into the formed area. The material does not require vibrating.
  7. The recommended application range of MasterEmaco S 466CI is from 45 to 85° F (7 to 29° C). Follow ACI 305 and 306 for hot or cold weather guidelines.

Horizontal Applications

  1. After removing all standing water, thoroughly scrub a thin layer of bond coat into the saturated surface with a stiff-bristled broom or brush. Do not dilute the bond coat with water. Do not apply more of this bond coat than can be covered with mortar before the bond coat dries. Do not retemper the bond coat.
  2. Immediately place the repair mortar from one side of the prepared area to the other. Work the material firmly into the bottom and sides of the patch to ensure good bond. Level the MasterEmaco S 466CI and screed it to the elevation of the existing concrete. Apply the appropriate finish.
  3. Finish the completed repair, as required, taking care not to overwork the surface. 
  4. The recommended application range of MasterEmaco S 466CI is from 45 to 85° F (7 to 29° C). Follow ACI 305 and 306 for hot or cold weather.
  5. A maximum of 90 minutes should be allowed to mix, place, and finish MasterEmaco S 466CI at 70° F (21° C).
