MasterEmaco S 5440CI

Flowable Structural Repair Mortar with Corrosion Inhibition to Reduce Shrinkage and Cracking

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.

Recommended Uses:

Structural repair of concrete elements such as:

  • Columns, piers, and cross beams of all bridges.

  • Cooling towers, 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 Makes MasterEmaco S 5440CI a Unique Solution?

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 (e.g., Putzmeister SP11) or pouring into the formwork.

  • High Early and Ultimate Strengths: Matches high-strength concrete found in structures.

  • High Modulus and Excellent Adhesion: Ensures 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: Protects reinforcing steel.

  • Low Chromate (Cr[VI] < 2 ppm): Low risk of skin irritation.

  • Chloride-Free: Does not add to the chloride load in contaminated structures.

  • Approved to AS/NZS 4020:2018: Suitable for contact with potable water (tested to the maximum exposure level).
