SpECgrout C1 may be used in grouting applications,
where a fluid/flowable grout is required and where
consistency of performance is essential. Typical applications are as follows:
· Anchor bolts
· Turbine base plates
· Generator base plates
· Pressing and milling machine base plates
· Non-shrink
· Consistent performance
· High bond strength to concrete and steel
· High compressive strength at early ages
allowing minimal downtime on machinery
· Low permeability
Preparation
It is essential that adequate preparation is carried out
prior to the application of SpECgrout C1. 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 consequently 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 C1 is a one-part cementitious grout.
SpECgrout C1 must be
mixed using a slow speed
electric drill fitted with a
SpEC Mixing Paddle.
This method is suitable for
small quantities and for
larger quantities it may benecessary to consider the
use of a grout pump. Please contact SpEC
Technical Department for more advice on the
type of pumps available.
The product cannot be mixed by hand
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 mixing vessel. The bagged 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).
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.
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.
SpECgrout C1 is supplied in 25kg bags. Each bag
when mixed with water will provide approximately
16.0 litres of mixed material depending on water
addition.
