High-strength, Fibre-reinforced Structural Repair Mortar
MasterCrete CI 5400 is a single component, extra high-strength, high modulus, shrinkage compensated structural repair mortar that meets the requirements of the new European Norm EN 1504 Part 3 class R4.
MasterCrete CI 5400 is used for the structural repair of concrete elements such as:
- Columns, piers and cross beams of all bridges
- Cooling towers and chimneys and other industrial environments
- Marine structures, water treatment and sewerage facilities
- Tunnels, pipes, outfalls and all below ground construction especially in harsh ground conditions
What are the unique features of MasterCrete CI 5400?
MasterCrete CI 5400 ensures load transfer based on its high modulus and adhesion to host concrete. There is not any need of a secondary reinforcement due to highly thixotropic mortar properties. MasterCrete CI 5400 contains Portland cement, graded sands, selected polymer fibres and special additives to significantly reduce the risk and incidence of shrinkage cracking. When mixed with water, it forms a highly thixotropic mortar that can easily be spray or trowel applied.
What are the benefits of MasterCrete CI 5400?
- Versatile – can be applied in extreme environments where active corrosion inhibition is required
- Shrinkage compensation systems and fibre reinforcement – minimise crack tendency
- Highly thixotropic – can be applied up to 50 mm without the need of secondary reinforcement
- High early and ultimate strengths – matches high strength concrete found in structures
- Outstanding workability – easy placing and finishing for applicators
- High modulus and excellent adhesion – ensuring load transfer in structural repair
- Excellent freeze/thaw resistance – suitable for all climates
- High carbonation resistance – suitable for exposed repairs in urban environments
- Sulphate resistant – suitable for contact with ground waters
- Very low permeability to water and chlorides – protection of reinforcing steel
- Low chromate (Cr[VI] < 2 ppm ) – low risk of skin irritation
- Chloride-free – does add to the chloride load in contaminated structures
