MasterEmaco® S 5400 (formerly Known as Emaco Nanocrete R4) 
High-strength, shrinkage compensated, fibre reinforced, structural repair mortar
 
MasterEmaco S 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.  MasterEmaco S 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.

RECOMMENDED USES 
MasterEmaco S 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 
• Water treatment and sewerage facilities 
• Tunnels, pipes, outfalls and all below ground construction especially in harsh ground conditions 
• Marine structures

FEATURES AND BENEFITS  

• Versatile – Can be applied inside and outside, on vertical and overhead surfaces, in dry and wet environments  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.
