MCON MICRO MORTAR is a ready to use dry powder which requires only addition of clean water at site to produce a free flowing non shrink repair micro concrete. It is composed of good quality cement, properly selected aggregates & additives. It is used & designed for repairing of damaged reinforced concrete elements like columns, beams & structure where the areas are restricted or not easily accessible for proper placement of concrete using vibrator. MCON MICRO MORTAR has excellent flowability, workability & proper particle size to reach small & congested reinforcement.
1. SURFACE PREPARATION
Clean the surface and remove loose concrete, dust, oil, paint, grease, waterproof coating, etc.
Expose fully any corroded steel in the repair area and remove all scale and corrosion deposits. Apply MCON STEEL RR for rust free bars.
For Cathodic Protection, apply MCON STEEL 2K or MCON STEEL ZRP over the cleaned rebars and allow it to dry before pouring of MCON MICRO MORTAR
Saturate the substrate with water to prevent absorption of water from the mixed material.
In case of a very old concrete substrate, it should be primed by applying one coat of MCON BOND EP â€“ epoxy bonding agent. Allow the bonding agent to reach tacky condition before pouring of mix concrete.
Use PAN Mixer for mixing of MCON MICRO MORTAR.
Charge 85-90 % of clean & potable mixing water (3.75 to 4 liters per 25 kg bag) to a PAN Mixer.
Start addition of Micro Concrete powder slowly under continuous mixing. Keep mixing for 2 minutes. Add balance quantity 15 â€“ 20% of mixing water & again mix for another 2-3 minutes to form a homogeneous, free flowing, uniform & lump-free mix.
Pour or pump the mixed MCON MICRO MORTAR into a watertight shuttering.
Cure the repaired concrete for minimum 7 days before removing the shuttering,
