Dr. Fixit Micro Concrete

Product Details

In structural repairs, especially in hard-to-reach or congested reinforcement areas, conventional concrete falls short. That's where Dr. Fixit Micro Concrete becomes a game-changer. This ready-to-use, non-shrink, free-flowing repair material is specially designed for restoring damaged reinforced concrete elements such as columns, beams, and structural members, particularly where compaction with a vibrator is not possible. Formulated with high-quality cement, graded aggregates, and performance-enhancing additives, it ensures excellent flowability, strength, and durability in critical repair applications.Features1. Ready-to-Use Dry Powder Pre-mixed at the factory, it only requires the addition of clean water on-site. This eliminates the need for extra cement or aggregates, saving time and ensuring consistency.2. Free-Flowing & Non-Shrink The material flows easily under its weight, filling voids and congested reinforcement zones without the need for vibration. It also prevents shrinkage cracks, ensuring volume stability.3. High Strength & Durability Formulated for structural repairs, it provides excellent compressive and bonding strength. This makes it suitable for repairing load-bearing elements like beams and columns.4. Excellent Workability & Flow Its well-graded particle size and advanced formulation allow it to flow smoothly into tight spaces. This ensures complete coverage and uniformity in hard-to-reach areas.5. Good Bond with Reinforcement & Concrete The product adheres strongly to steel and existing concrete, creating a monolithic repair structure. This enhances the structural integrity and prevents delamination.6. Easy Placement in Inaccessible Areas Ideal for confined spaces where traditional concrete placement tools cannot reach. It flows and fills effectively, ensuring complete and effective repairs even in challenging zones.Step-by-Step Application MethodStep 1: Surface PreparationClean the repair surface thoroughly.Remove loose concrete, rust, grease, and dust using a wire brush, chisel, or high-pressure water jet.Expose the steel reinforcement and clean it to remove corrosion.Step 2: Substrate Pre-WettingPre-wet the prepared surface with clean water for at least 30 minutes.Ensure the surface is a saturated surface dry (SSD) before pouring micro concrete.Step 3: ShutteringFormwork must be strong, watertight, and well-supported to hold the pressure of the micro concrete.Seal all joints to prevent leakage.Step 4: MixingAdd approximately 13–14% clean water to the powder (as per the technical datasheet).Use a mechanical mixer for 3–5 minutes to ensure a homogeneous, lump-free mix.Mix until you get a free-flowing consistency.Step 5: PlacementPour the mixed material directly into the formwork.Avoid vibration.Let the micro concrete flow under gravity.Ensure continuous pouring without interruption for best results.Step 6: CuringBegin moist curing as soon as the surface sets (usually within 6–8 hours).Continue curing for at least 7 days using a wet hessian cloth or curing compound.
