Mivan aluminium formwork offers exceptional efficiency and high-quality concrete finishes. However, like any construction system, it can encounter challenges. This article provides comprehensive guidance on troubleshooting common issues with Mivan aluminium formwork to minimize downtime and ensure optimal project outcomes.
Formwork Alignment Issues
Forms Not Aligning Properly:
Inspect the site conditions for uneven ground or obstacles that may hinder alignment. Ensure that the formwork panels are plumb and level using a spirit level or laser. Check the alignment pins to ensure they are properly engaged and not bent.
Panels Not Interlocking Correctly:
Verify that the panels are compatible and compatible with the connection system. Clean the interlocking surfaces of debris or damage that may prevent proper engagement. Use a rubber mallet to gently tap the panels into place, ensuring secure connections.
Concrete Leakage
Leakage from Panel Joints:
Inspect the gaskets and seals between the panels for damage or misalignment. Tighten the bolts connecting the panels to ensure a snug fit. Use a non-shrinking sealant or caulk to seal any gaps or imperfections in the joints.
Cracks in Concrete:
Excessive concrete pressure or inadequate formwork support can cause cracks. Ensure that the formwork is properly braced and supported to withstand anticipated concrete loads. Adjust the concrete mix to reduce excessive pressure and use crack-resistant admixtures if necessary.
Surface Defects
Honeycombing:
Insufficient concrete compaction can lead to honeycombing. Vibrate the concrete thoroughly to eliminate air pockets. Ensure that the concrete mix has a suitable consistency and is not too wet or too dry.
Blisters:
Air entrapped within the concrete can form blisters. Use an air-entraining agent in the concrete mix to create tiny air bubbles, which will reduce the risk of larger blisters. Wet the formwork before pouring concrete to prevent entrapped air between the concrete and formwork.
Durability Issues
Corrosion:
Protect the aluminium formwork from exposure to harsh chemicals, salts, and moisture. Clean and inspect the formwork regularly and apply protective coatings or paints as needed. Store the formwork in a dry, well-ventilated area when not in use.
Damage:
Handle the aluminium formwork with care to prevent denting or bending. Inspect the formwork before each use for damage that may affect its performance. Repair or replace damaged components promptly to ensure safety and prevent further issues.
By understanding and troubleshooting these common issues with Mivan aluminium formwork, contractors can ensure smooth project execution, minimize delays, and achieve high-quality construction outcomes.
