Emaco 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, making it particularly useful in cold store applications. It 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. Used for thicknesses above 20mm only, for depths of 30mm and above up to 10kg of 10mm single sized coarse aggregate may be added. Size: 20kg
