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.

MasterEmaco® P 5000 (formerly known as Emaco Nanocrete AP) 
Single component, cement based, multi-use, bonding and active protective primer

MasterEmaco P 5000 active primer, not only reinstates a high pH environment it also contains active corrosion inhibiting additives for the protection of reinforcement steel.  It can also be used as an adhesive bonding slurry for subsequent repair mortars.  When mixed with water, it forms a slurry that can be applied by brush to the clean exposed reinforcement, or directly on the dampened, prepared concrete substrate when used as a bonding coat.

RECOMMENDED USES 
MasterEmaco P 5000 is used for the protection of reinforcement steel: 

• When steel is visible and the available depth of cover is less than 10 mm 
• When concrete is contaminated with chlorides 
• In critical environments when extra protection is specified 
• With MasterEmaco R 5200CI repairs when steel is visible 
• When the timing at the jobsite does not allow for the repair mortars to be applied immediately after cleaning the steel MasterEmaco P 5000 can also be used to aid bond and application properties of hand applied repair mortars in extreme thicknesses and conditions.

• Meets all major international norms - for steel priming in concrete repair systems. 
• Excellent rust inhibiting properties - as it reinstates a high pH environment. 
• Contains active corrosion inhibitors - to further protect the steel. 
• Polymer modified -for additional adhesive bond to the steel. 
• Long life repairs - Does not reduce adhesion of repair mortars to steel  
• Wide Compatibility -with steel reinforcing bars and concrete or repair mortars. 
• Fast curing -to save time and money 
• Simply mixing –just add water
• Multi-use - can also be used as a bonding slurry to improve bond and application thicknesses of MasterEmaco repair mortars on prepared concrete surfaces. 
• Light grey/off white colour - for easy site control of reinforcement coverage 
• Only use what is needed -Supplied in reusable air-tight containers 
• Low hazard -Low chromate (Cr[VI] < 2 ppm)
