MasterEmaco T 545

Rapid setting, high early strength repair mortar based on magnesia-phosphate cement for temperatures from -20°C to >30°C

What is MasterEmaco T 545?

MasterEmaco T 545 is a specially formulated repair mortar, based on magnesia-phosphate cement pre-mixed with selected aggregates, which gives controlled, extremely high early strengths in temperatures ranging from -20°C (or lower) up to over 30°C.
MasterEmaco T 545 provides a repair material for concrete slabs which reaches an adequate strength for trafficking, or other use, at a very early age.  It is also suitable for use as a repair medium at low ambient temperatures.
When MasterEmaco T 545 is added to the gauging water and mixed, an exothermic chemical reaction commences and a chemical setting process takes place within approximately 15 minutes (at 20°C).  The material hardens to give sufficiently high early strength to receive heavy traffic within a period of less than one hour at 15 - 20°C.
Application depth
20mm to 75mm unfilled
>75mm to 150mm filled with 10mm aggregate.

What is MasterEmaco T 545 used for?

For use in concrete repair situation where the minimum delay and work disruption is of the utmost importance.

  • Cold store floor areas
  • Concrete roads and nosings
  • Bridge decks
  • Quays/crane rails
  • Industrial floor areas
  • Loading bays and warehouses
  • Around fixing bolts
  • Raising and levelling manhole covers, gratings, hydrants etc.

What are the benefits of using MasterEmaco T 545?

  • High strength at a very early age (45 minutes)
  • Minimum delay to traffic and production.  When used to repair concrete pavings, it permits early re-opening to traffic - within 45 minutes at 20°C.
  • Ready for use.  Only requires the addition of water (see Mixing)
  • Excellent bond to concrete and steel reinforcement.  No secondary bonding agents required
    Highly durable.  Excellent resistance to de-icing salts
  • High freeze/thaw resistance
  • No curing required
  • Can be placed in sub-zero temperatures
  • 'Non-shrink'
  • Modulus and Thermal properties similar to concrete
  • Lower permeability than cementitious mortars
  • Chemically resistant to fuel, engine oils and urine
  • Inhibits corrosion in steel even in the presence of chlorides
