​​MasterEmaco S 5440CI 

Flowable, structural repair mortar with active corrosion inhibition used on concrete elements 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.

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