MasterEmaco S 5400CI - High strength, shrinkage compensated, fibre reinforced, structural repair mortar with active corrosion



How does MasterEmaco S 5400CI work?

MasterEmaco S 5400CI 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.

MasterEmaco S 5400CI  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 MasterEmaco S 5400CI?

MasterEmaco S 5400CI  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. MasterEmaco S 5400CI 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 MasterEmaco S 5400CI?

  • 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
