Dr. Fixit Micro Concrete 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. Dr. Fixit Micro Concrete has excellent flowability, workability & proper particle size to reach small & congested reinforcement. Specification Dr. Fixit Micro Concrete meets the requirement of ASTM C 109: 99, ASTM C 307, BS 1881 Part 207 Areas of Application Repair of 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 members) Features & Benefits £ Pumpable - Can be pumped or poured into restricted locations. Flowable - Flowable mortar hence does not require compaction. Shrinkage compensation – Controlled expansion system which compensates for shrinkage and settlement in the plastic state. Strength - Develops high initial and ultimate compressive strength. Moisture resistant - Offers excellent resistance to moisture ingress. Durablity - Makes repaired sections highly durable & compatible to parent concrete. Thickness build up - Can be applied at 100 mm thickness at one stroke, Chloride content - Contains no chloride based additive so prevents corrosion of reinforcement. Early reinstatement -Rapid strength gain helps in early reinstatement & removal of shuttering.
Method of Application

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. Light shot blasting is highly recommended. Apply Dr. Fixit Rust Remover for rust free bars. For Cathodic Protection, apply Dr. Fixit Epoxy Zinc Primer over the cleaned re-bars and allow it to dry before pouring of Dr.Fixit Micro Concrete. 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 Dr. Fixit Epoxy Bonding Agent. Allow the bonding agent to reach tacky condition before pouring of mix concrete.

2. MIXING
Use PAN Mixer for mixing of Dr. Fixit Micro Concrete. £ 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 – 20% of mixing water & again mix for another 2-3 minutes to form a homogeneous, free flowing, uniform & lump-free mix.
