FAP NANO GROUT CN

FAP NANO GROUT CN

Plasticizing & Expanding Grout Additive

FAP Nano-Grout CN is a blend of non-ferrous metallic expanding agents and polymer based water reducing agents. A catalyst is added which promotes controlled expansion. Used an admixture for cementitious grouts where a reduced water/cement ratio and positive expansion is required. Applications include bed grouting, duct grouting, non-shrink grouting infilling and jointing.



Applications & Advantages

  • Cement plasticizing and water reducing action at low water cement ratios.
  • At low water cement ratios, improved permeability and higher strengths are achieved. Controlled rates of expansion. Ensures full contact between grouted surfaces.
  • Suitable for use with all common cement types.
  • For onsite production of shrinkage controlled cementitious grouts. Suitable for most construction applications.

Recommended Usage

Neat cement grout : Use 0.5% FAP Nana-Grout CN by weight of cement. Maximum water content 45 litres per 100 kg of cement.

Cement/sand grout : When using equal parts of sand and cement use 0.5%  FAP Nano-Grout CN by weight of cement. Maximum water 55 liters for 200 kg batch. Plasticizing: Use 0.5% FAP Nano-Grout CN by weight of cement and reduce water contents by 10-15%. The same workability will be achieved with a 10% increase in compressive strength.

Instructions for Use

Surface Preparation : The areas to be grouted or repaired must free from dust, loosely adhered material, and plaster and cement droppings, grease oil and paints etc. The substrate must be thoroughly pre-wetted to account for excessive absorption into the parent concrete. The ideal condition is saturated, surface dry.

Mixing : Only mix as much grout as needs to be used immediately. Add the required quantity of water to a clean mixer first. Then add pre-weighed cement. FAP Nano-Grout CN and finally sand (if used) allowing one minute mixing between each addition. Mix for approximately five minutes in total. Visually check for complete dispersion of the grout. Small batches can be mixed with a bucket and slow speed drill and paddle. For large quantities and continuous grouting use a designated mechanical, forced action mixer.

Curing : Complete curing of cementitious products is critical. In most cases the volume of the repair mortar or grout is insignificant when compared to the parent concrete. This can mean rapid moisture loss into the dry substrate. Poor curing will result in shrinkage cracks and loss of strength. The use of a suitable curing compound is recommended. Water ponding may be used providing this is maintained for at least 7 days. The grout must not be allowed to dry for the first 7 days of curing.

Health & Safety

As with all chemical products, caution should always be exercised. Protective clothing, Such as gloves and goggle, should be worn.
