Shrinkage compensated, flowable, structural repair mortar with active corrosion inhibition
How does MasterCrete LH 5460 work?
MasterCrete LH 5460 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.
MasterCrete LH 5460 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 MasterCrete LH 5460?
MasterCrete LH 5460 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 MasterCrete LH 5460?
- 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
