Abstract
Frost resistance of fibre reinforced concrete with 2.5-4.2% air
and 6-9% air (% by volume in fresh concrete) casted in the
laboratory and in-situ is compared. Steel fibres with hooked ends
(ZP, length 30 mm) and polypropylene fibres (PP, CS, length 12 mm)
are applied. It is shown that· addition of 0.4-1% by volume of
fibres cannot replace air entrainment in order to secure a frost
resistant concrete; the minimum amount of air needed to make the
concrete frost resistant is not changed when adding fibres· the
amount of air entrainment must be increased when fibres are added
to establish the same amount of air pores as in the corresponding
concrete without fibres
