SikaEmaco® S 466

(former MEmaco S 466)

PUMPABLE, FREE FLOWING, SHRINKAGE COMPENSATED MICRO-CONCRETE FOR GROUTING AND REPAIR

SikaEmaco® S 466 is a cementitious, pre-bagged, free flowing, one component, non-shrink precision microconcrete with high early and ultimate strength.
Suitable for use in hot and tropical climatic conditions.

SikaEmaco® S 466 is an easy to use precision microconcrete requiring only the addition of water. It offers the following beneficial properties: ▪ Easy to mix
▪ Very good flow characteristics
▪ Adjustable consistency
▪ Moderate heat of hydration
▪ Shrinkage compensated
▪ High final strength
▪ Non-flammable
▪ Vapour permeable
▪ Compatible with the properties of typical concrete

Usage

SikaEmaco® S 466 precision micro-concrete is used for repair and grouting in various applications such as:
  • Structural repair of deteriorated concrete
  • Columns in precast construction
  • Casting sections or members where the volumes required are too large for conventional grouts, and too small and inaccessible for normal concreting applications.
  • Cavities, gaps and recesses
  • Re-profiling of damaged concrete members and reprofiling of pile tops using formwork for both pouring and pumping techniques.

Application steps

MIXING

Add water according to the desired consistency into a clean mixing vessel before slowly adding the SikaEmaco® S 466 powder. SikaEmaco® S 466 is best mixed in a forced action mixer, for 2 to 3 minutes or until the mix is free of lumps, not longer than 5 minutes.

Slow speed drill (maximum 500 rpm, double paddle hand mixer) can be used for mixing of 25 kg bags. For 40 kg and 50 kg bags, action force mixing by pan mixer or equivalent is required. Normal tumble type concrete mixers are not suitable.

Do not mix more grout than can be placed within 15 to 20 minutes. Do not add extra water or other ingredients. Mix only full bags for the best result.

Note: Always start with minimum recommended quantity of water (water/powder ratio), only if required, gradually add water to desired consistency. Do not exceed maximum allowed limit of water per bag weight.

APPLICATION

Before pouring let the mixed grout stand for approximately 5 minutes after mixing to allow entrapped air to escape. Pour into the prepared area such that the grout has the shortest distance to travel. Ensure that air displaced by the grout is allowed to escape. When carrying out the base plate grouting, ensure a sufficient head of pressure to keep the mortar flowing. All exposed areas of the mortar surface should be kept as
small as possible. 

CURING TREATMENT

Treatment of exposed surfaces with Sika® Antisol® range curing compound, is highly recommended for large areas of application. Use other approved curing methods such as polyethylene sheeting or wet hessian only for small exposed areas. Do not commence fogging until final set has been reached.

 

CLEANING OF EQUIPMENT

Clean equipment and mixer immediately after application with water. Hardened material can only be removed mechanically.
