.SpECgrout C2 may be used in all grouting applications, where maximum contact area is required and
where high flow characteristics are desired, such as
during the installation of:
· Anchor bolts
· Precast units
· Crane rails
· Turbines
· Generators
· Pressing and milling machines
· By altering the material’s consistency, other
operations may be carried out, for instance,
filling holes due to formwork ties
· Unique non-metallic shrinkage compensation
provides maximum contact between baseplate
and hardened grout
· Consistent high performance
· Extremely high flow characteristics with
excellent retention of flow, even at high ambient
temperatures
· Suitable for placing by pump
· High bond strength to steel and concrete
· High compressive strength at early stages
allowing minimal downtime on machinery
· Good impact and fatigue resistance
· Micro silica content enhances strength and
durability
· Extremely low permeability
Preparation
It is essential that adequate preparation is carried
out prior to the application of SpECgrout C2. 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. Prior to 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.
All formwork should be sealed to prevent loss of
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 C2 is a one-part cementitious grout.
SpECgrout C2 must be mixed using a slow speed
electric drill fitted with a SpECgrout mixing paddle.
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. Thebagged powder is then
added slowly whilst mixing. A mixing time of not less
than five minutes is required to ensure adequate dispersal of the ingredients.
The recommended water used per 25kg bag is
5.5 litre to 7.25 litre (for plastic/flowable
consistency).
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 C2 is supplied in 25kg bags. Each bag
when mixed with water will provide approximately
12 litres of mixed material depending on water addition
