Feb® Febmix® DH

Powder mortar plasticiser in a handy sachet pack form

Feb® Febmix® DH is a mortar plasticiser in powder form for use as an alternative to lime or as a supplement to lime to aid mortar durability. Complies with EN934-3. Feb® Febmix® DH will entrain microscopic air bubbles into cement mortars in a controlled manner as specified in EN934. Air entrained mixes produce greatly enhanced working properties with a reduced demand for mixing water. Feb® Febmix® DH also improves frost resistance in both freshly laid and hardened mortars, as the microscopic air bubbles entrained provide space for expansion of water due to freezing.

  • Economical: - reduced labour costs - reduced wastage - increased spread rates.
  • Helps reduce efflorescence.
  • Reduces bleed and segregation in the mix.
  • Improved bond.
  • Improves frost resistance.

Application

Consumption

Recommended Dosage

Feb® Febmix® DH is added at the rate of 1 sachet per 25 kg bag of cement. Always use the type of sand recommended for a particular application. Test mixes should be carried out to determine optimum dosage.
Application steps

APPLICATION INSTRUCTIONS

Feb® Febmix® DH may be added directly into the mixing drum after the addition of sand or pre-mixed with the gauging water. The use of Feb® Febmix® DH pre-weighed sachets introduced directly to the mix optimises control of dosage and minimises wastage.

MIXING

The action of Feb® Febmix® DH is entirely physical and therefore requires an efficient mixing action. If mixing is to take place by hand the mix must be well “turned over” to achieve the maximum plasticising effect. Mortar selection should be made in line with the relevant National Standards and Codes of Practice. The table above gives indicative mix designs relative to uses with and without Feb® Febmix® DH. Portland Cement: Lime, sand mixes which also include an air entraining plasticiser have been shown to be particularly durable in accelerated testing.
