Feb® FebSET® 45

RAPID High Strength Repair Mortar

Feb® FebSET® 45 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 up to over +30 °C. Feb® FebSET® 45 can be modified with 10 mm aggregate for use in depths over 100 mm. Feb® FebSET® 45 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 Feb® FebSET® 45 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 to +20 °C.  

  • 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).
  • High bond strength. No secondary bonding agents required.
  • Highly durable. Excellent resistance to de-icing salts.
  • Can be placed in sub-zero temperatures.
  • Non-shrink.

Consumption

Yield

Per 25 kg (mixed as directed):
Approximately 11.6 L when mixed as directed. Addition of 10 kg coarse aggregate/25 kg Feb® FebSET® 45 will increase yield by approximately 30 %.
Application steps

MIXING

The following sequence must be followed at all times when mixing Feb® FebSET® 45:

1. A suitable mixer (i.e. tilting drum) should be located as near as possible to the area of work.

2. The amount to be mixed should never exceed that which can be transported, placed, compacted and finished within ten minutes.

3. Wet down the mixer and drain off the free water.

4. Pour the correctly measured amount of clean water into the mixer first. Do not add the water to Feb® FebSET® 45.

5. When adding coarse aggregates, these must be added to the water before the addition of Feb® FebSET® 45 into the mixer.

6. Empty the full contents of the Feb® FebSET® 45 bag into the mixer. Minimum mixing time is 1 minute.

Workability: Although stiff at the outset, workability will improve as mixing continues, to give the desired flow characteristics. On no account must further water be added. It is also essential that no admixtures are included.

Placing and Finishing: Pre-wet the area to be treated and remove surplus water. Always ensure correct compaction and level surface by ruling with a firm, straight edged tamping bar.

Cold Weather Working: Below +5 °C down to cold store temperature of -20 °C, pre-warm the mixer and equipment with warm water before batching. The mixing water should be warmed to a temperature of +25 °C to +30 °C.

Hot Weather Working: Where the temperature is above +30 °C, the use of chilled water in the mix will extend open time. Keep mixing equipment cool via use of cold water etc.

Wet Weather Working:  Protect areas for 30 mins minimum via tenting etc.

Thickness: The thickness of Feb® FebSET® 45 should not be less than 10 mm at all times. For depths greater than 100 mm, a 10 mm single sized coarse pre-wetted aggregate, complying with EN12620, may be added up to a rate of 10 kg per 25 kg Feb® FebSET® 45.

CLEANING OF TOOLS

Clean all equipment quickly with water, do not allow to set
