benefits are among the reasons
contractors are turning to macro-
synthetic fibres, as well as using traditional
reinforcement methods. When applied to
external slabs, polypropylene fibres act as
consistently distributed reinforcement and
crack control, producing a hard-wearing and
durable concrete that provides long-term
Corrosion of steel reinforcement caused
by chloride contamination is a common,
long-term threat to slabs all over the world.
The process leads to spalling and cracking,
and in many cases, drawn-out and costly
refurbishment to remove, repair and maintain
the damaged areas.Macro fibres enhance
the toughness of the concrete and alleviate
the need for steel fabric reinforcement, when
used with the appropriate design.
The system reinforces against abrasion
and reduces corrosion damage in the event
of water ingress, as it doesn’t rust or corrode.
Macro-synthetic fibres also offer safer, faster
and easy-handling solutions for contractors.
By comparison, steel fibres require a much
higher quantity of product, and require more
manual handling than macro-synthetic fibres.
Placing traditional steel fabric
reinforcement is a labour-intensive operation,
as it is often difficult to determine whether
the fabric has been placed correctly within
the slab.Macro fibre-reinforced concrete
scores a critical advantage over equivalent
processes in terms of on-site hours and costs,
as placement, compaction and finishing of
slabs is more efficient.
As well as helping to streamline the
concrete placement process,macro-
synthetic fibres are also considered ‘cleaner’
technology. Its use on site results in a lower
carbon footprint (compared with steel
reinforcement) – a fact worth considering, as
the UK Government struggles to maintain
its pledge to cut the country’s emissions by at
least 80% of 1990 levels by 2050.
