SpECgrout C5 as a general purpose grout may
be used in a variety of situations such as the
installation of:
· Anchor bolts
· Structural column base-plates
· Mixing and storage vessels
· Turbines
· Generators
· Pressing and milling machines
· Non-gaseous, non-metallic shrinkage
compensation, provides maximum contact
between baseplate and hardened grout.
· Consistent high performance
· Excellent retention of flow even at high
ambient temperatures
· High bond strength to steel and concrete
· High compressive strength at early stages
allowing minimal downtime on machinery
· Good impact and fatigue resistance
· Oxidizing catalyst free
· Extremely low permeability
· Chloride free
· Bleed resistant
Preparation
It is essential that adequate preparation is carried
out prior to the application of SpECgrout C5. This
preparation should ensure the removal of all grease,
oil and loose material.
To avoid absorption and reduction in flow
characteristics, it is essential that the prepared
substrate is soaked with clean water for a few hours
prior to grouting. Before placing the grout any water
remaining on the surface should be removed by
blowing clean with oil free compressed air.
The underside of the base plate to be grouted
should be clean and any oil or grease MUST be
removed. The underside should preferably have no
geometry which would impede the flow of grout.
Should cruciforms be present, it is essential that air
release holes are drilled through the base plate to
avoid trapping air hence reducing the total contact
area.
grout during pouring. The formwork should be tight
to the base plate and parallel to the direction of
flow. A gap of around 100mm is required at the
pouring hopper with a gap of around 50mm at the
opposite end.
Mixing
SpECgrout C5 is a one-part cementitious grout.
SpECgrout C5 must be mixed using a slow speed
electric drill fitted with a mixing paddle of the
Metabo accessories type 31 043. This method is
suitable for small quantities, for larger quantities it
may be necessary to consider the use of a grout
pump. Advice can be provided by our Technical
Service department on the type of pumps available.
Good planning is essential to ensure a continuous
flow of grout once pouring commences.
The specified water
quantity should be
measured in an accurately
graduated vessel and
added to the mixer. The
bagged powder is then
added slowly whilst mixing. A mixing time of not
less than 5 minutes is required to ensure adequate
dispersal of the ingredients.
The recommended water used per 25kg bag is
7.25 litres.
The product cannot be mixed by hand
Application
The grout should be poured immediately after
mixing and certainly not more than 20 minutes
after mixing is complete to take full advantage
of the high flow properties.Again, planning is imperative to ensure that
sufficient grout is available to allow continuity
of placing. The mixed product should always be
poured from the hopper end of the formwork.
On no account should grout be poured from more
than one side of the base plate. Maintenance of a
fluid head is essential to avoid air entrapment.
Once the grouting has been completed, all exposed
areas of grout should be cured immediately using
SpECcure WE curing membrane.
SpECgrout C5 is supplied in 25kg bags. Each bag
when mixed with 7.25 litres of water will provide
approximately 16.10 litres of mixed material.
