ShaliFix MC is a high strength material, which is easy to use with an extended working time for ease of placement. It is similar in appearance to concrete and is suitable for use as a topping, patching mortar or repair material on horizontal surfaces.
Application (Mainly recommended for repair of):
- Repair of damaged concrete structures like columns / beams / slabs etc.
- Parking decks.
- Floor toppings.
- Joint repairs.
- Equipment bases.
- Pedestals.
- Pavements.
Advantages:
- Can be used as a pumpable or pourable repair concrete where access is restricted.
- Highly fluid to allow for placement without vibration.
- Compensates for shrinkage by expansion.
- Premixed, ready to use, having rapid strength development.
- Good bond with old concrete.
- High strengths with low permeability.
- Chloride free.
Surface Preparation:
- New concrete must be a minimum of 28 days
- Remove all loose gravel, dirt, oil, grease and foreign matter by jet of dry air and clean the surface mechanically to make it textured before application
- Shot blast or scarify the surface to give a profile of minimum 1/8” (# mm) and expose the large aggregate of the concrete
- All concrete must possess an open surface texture with all curing compounds and sealers removed. Several hours prior to placing, the concrete substrates should be saturated with clean water. Remove any standing water. Alternatively, use a bonding system.
Material Preparation:
- Slowly empty bag of ShaliFix® MC in 3.5 L of water, while mixing with slow speed mixture fitted with a suitable mixing paddle till homogenous mix is obtained
- After achieving consistency in the mix, add the remaining 1 L of water and continue mixing till applicable consistency is achieved
- Allow the mix couple of minutes to let the entrapped air escape
- For repair deeper than 100 mm, mix ShaliFix® MC with properly graded 5 mm to 12 mm silt free aggregate to minimize temperature rise. The quantity of aggregate required may vary depending on the nature and configuration of the repair location. It should be a max. of 8 – 10 kg of aggregate per bag of ShaliFix® MC
- Use the entire prepared material within the pot life time.
Application of Material:
- Prime the prepared surface with ShaliPrime S
- Saw cur edges to ¼ ” (6 mm) deeper than the topping thickness and repair to provide a locked in reinforced edge. Moving joints as in the case of expansion joints should be brought up through the repair by saw cutting or with the use of divider strip
- Exposed rebar may be treated with an anti-corrosion coating with ShaliPrime Zn R. Remove all loose rust and scaling, preferably by sandblasting to white metal prior to coating the rebar
- Finish to desired texture. On large floor areas, use screed strips as guides in combination with vibratory screeding to level.
- If placed by pump, standard concrete pumping practice should be followed
- If poured in the form work, avoid air entrapment by pouring from one side only
- Finish the repair material to the desired texture. Do not add additional water to the surface during the finishing operation
- To prevent surface cracking, cure the floor with curing compound, such ShaliCure Acrylate. In hot, windy or direct sunlight situations, re-wet the surface after the curing compound has dried and cover with polyethylene for a minimum of three days
