Shrinkage compensated, flowable, structural repair mortar with active corrosion inhibition

How does MasterEmaco S 5440CI work?

MasterEmaco S 5440CI is a single component, extra high-strength, high modulus, shrinkage compensated structural repair mortar that meets the requirements of EN 1504 part 3 class R4.

MasterEmaco S 5440CI 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
  • All form and pour repairs

What are the unique features of MasterEmaco S 5440CI?

MasterEmaco S 5440CI contains Portland cement, graded sands and special additives to significantly reduce the risk and incidence of shrinkage cracking.  When mixed with water, it forms a highly fluid mortar that can easily be pumped or poured into formwork.

What are the benefits of MasterEmaco S 5440CI? 

  • Versatile – can be applied in extreme environments where active corrosion inhibition is required
  • Shrinkage compensated  – minimises crack tendency
  • Highly fluid – can be applied by pump (eg Putzmeister SP11) or pouring into formwork
  • High early and ultimate strengths – matches high strength concrete found in structures
  • 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 – 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
