Feb® Febspeed

Liquid Accelerator & Hardener for Mortar, renders and screeds

Feb® Febspeed is a liquid admixture formulated to accelerate the setting time of cement based mortar, non-reinforced concrete, renders and screeds. Also provides frost protection in the wet mortar during the setting period, even in sub-zero temperature and can also be used neat with cement as a plugging aid.

  • Multi-faceted product.
  • Reduces setting time.
  • Increases early strength.
  • Minimises waiting times on finishing operations.
  • Reduces strike times in production.
  • Increases productivity.
  • Optimises mould usage.
  • Economical in use.

APPLICATION INSTRUCTIONS

As an Accelerator:

Pre-mix Feb® Febspeed with gauging water; check amount of water to be used in the mix, sand grading and condition. The table below gives indicative dosage rates relative to cement and water addition rates:

Mixing proportion to cement used

Concrete/ Cement/ Mortar

5 Litre Feb® Febspeed per 100kg of cement

Mixing proportion to gauging water

*Concrete

5 litres Feb® Febspeed to 40 litres mixing water

Cement Mortar

2.5 litres Feb® Febspeed to 35 litres water

Amount of Feb® Febspeed per cubic metre of concrete/ mortar

Concrete

11.25 litres

Cement Mortar10 litres

*Note: Based on commonly used mixes having a fairly high slump with approximately 100 litres of mixing water used per cubic metre of concrete (the 100 litres includes the added Feb® Febspeed).

As a Floor Hardener:

Incorporate Feb® Febspeed with gauging water at a rate equivalent to 2.5 to 5 litres of Feb® Febspeed per 50 kgs of cement used. The concrete should not be gauged weaker than 1:2:4. If granolithic topping should be appropriate then a specification of 2 parts 3-6 mm clean grano (no dust) to ½ part concreting sand to 1 part cement. For selection of relevant mix designs and installation techniques refer to BS 8000 Part 9 and BS 8204 Part 2. NB: Many of the benefits to be gained from the use of Feb® Febspeed as a hardener can be negated by bad practice and placement techniques. Refer to relevant BS document for guidance on placement, curing etc.

As a Super Rapid Hardener:

  Feb® Febspeed may be mixed neat with fresh ordinary Portland Cement in small quantities for use immediately as a plugging compound.
