Areas of Application
- Repair to damaged reinforced concrete elements like beams, columns, wall etc., where access is restricted and compaction is not possible.
- For Jacketing of RCC columns to increase load taking capacity (strengthening of a vertical member)
Method of Application
- Clean the surface and remove loose concrete, any dust, oil, paint grease etc.,
- Expose fully any corroded steel in the repair area and remove all scale and corrosion deposits. Shot blasting is highly recommended
- Apply Dr. Fixit Epoxy Zinc Primer over the cleaned re-bars and allow to dry before continuing
- Saturate the substrate with water to prevent absorption of water from the mixed material of Dr. Fixit Micro Concrete
- For a dry substrate, it should be primed by applying one coat of Dr. Fixit Epoxy Bonding Agent.
- Mix Dr. Fixit Micro Concrete with water (3.75 to 4 litres per 25 kg bag) till homogeneous mix is obtained, at 30oC
- Mixing should be done thoroughly with a forced action mixer of adequate capacity, atleast for 5 minutes
- Pour or pump the mixed Dr. Fixit Micro Concrete into a watertight shuttering in the repaired area, when primer becomes tacky
- Cure the repaired surface for minimum 7 days.
Precautions & Limitations
- Dr. Fixit Micro Concrete can applied in section upto 100 mm deep.
- For thickness more than 100 mm, addition of pre-calculated aggregates may be required. Consult local Pidilite office for more details.
- Strictly follow water-powder ratio as specified
- Ensure that the shuttering is 100% watertight
- Ensure full exposure of reinforcement steel
- Consult structural engineer if the diameter of rebar is reduced by more than 20% than original diameter.
