Non Shrink Grout (Ultra Grout-50-70) is a non-shrink, non-ferrous grout that is easily mixed for grouting at any consistency i.e. dry-pack, plastic or pourable. Non Shrink Grout (Ultra Grout-50-70) does not contain any iron particles, chlorides or gypsum and will not corrode, shrink, rust or ravel even under constant moist conditions. When mixed according to instructions, it produces a high compressive strength due to a technology that reduces the water-cement ratio.
Benefits - Retain its workability for 2 hours.
- Ready to use, just addition of water is required.
- High density, increases bond to metal, wool and other construction materials
- Will not rust, bleed.
- Requires no special treatment.
- Clean finish
- Density increases wear ability, permeability withstand heat & thermal shock.
- Water tight, resist freeze & thaw water conditions and salt penetration.
- Resists a variety of oils & Chemicals
- Contains no free lime will not produce efflorescence.
ApplicationsUltra Grout is recommended for grouting the following.
- Heavy equipped & machinery bases
- Structural columns
- Pump & equipment bases
- Power Line stations.
- Pre-case Tee joints
- Re-pointing mortar joints
- Structural cracks
- Bearing Plates
- Rail posts, seating bolts
- Post tensioned cables
- Patching
Water Requirements - Plastic : 0.14
- Flowable mix : 0.16
- Fluid mix : 0.18
Mixing and ProportionsAdd required water to get consistency. For uniform mix, use paddle or drum type mechanical mixers. Do not mix more than 5 minutes. Place grout after mixing. The working time of grout is 2 hours.
Surface EntrapmentsFirst remove all dust, oil, grease or contaminants from surfaces to be grouted, and then remove all loose material. Metals which will come in contact with grout must be derusted or freed of paints, oils & greases. To avoid entrapment of air, provide air relief openings where required. Prior to placement of grout, thoroughly soak or dampen all concrete areas to be grouted. Then remove excess water from voids & holes.
FormingFor machinery bases and column base flats, follow standard forming procedures, which permit complete and proper placement of fluid grout, including use of head forms. All support elements should be anchored to prevent movements. Do not remove supports until grout has sufficiently hardened. Wool surfaces, which absorb moisture, should be pretreated with forming oils.
