Product Description
FEBSPEED is a liquid admixture that accelerates the setting time of mortar, non-reinforced concrete, renders, screeds and paving’s. FEBSPEED has been tested to the requirements of EN 934 Part 3.
Typical Uses
- For use in the acceleration of screeds and paving where a reduction in set time is required; also suitable for use as an accelerator in non reinforced concrete, as a super rapid hardener for plugging of leaks in concrete.
- FEBSPEED can also be used as an aid to cold weather working.
Features & Benefits
- Multi-faceted product.
- Reduces setting time.
- Increased early strength.
- Minimises waiting times on finishing operations.
- Reduces strike times in production.
- Increases productivity.
- Optimises mould usage.
- Economical in use.
Instructions for Use
As an Accelerator:
Pre-mix FEBSPEED with gauging water; check amount of water to be used in the mix, sand grading and condition. Table A gives indicative dosage rates relative to cement and water addition rates:
As a Floor Hardener:
Incorporate FEBSPEED with gauging water at a rate equivalent to 2.5 to 5 litres of 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 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:
FEBSPEED may be mixed neat with fresh ordinary Portland Cement in small quantities for use immediately as a plugging compound.
Storage
Protect from temperature extremes. Will freeze but can be reconstituted by stirring after thawing.
Shelf Life
Minimum two years when stored in accordance with the manufacturer’s instructions.
