Master Builders MasterEmaco T 545 50lb Bag 51701276

MasterEmaco T545 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 T545 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 T545 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. 

Features/Benefits

• 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
• Inhibits corrosion in steel even in the presence of chlorides
• 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

MasterEmaco T545 is supplied in 25kg sacks.  25kg of MasterEmaco T545 combined with the correct amount of water (see Guide to Application, Mixing) will yield approximately 11.6ltrs. Where coarse aggregates are added at the rate of 10kg per 25kg MasterEmaco T545, an approximate increase in yield of 30% will be achieved.
