ANCHOREX

Generally
bonding of old mortar to new mortar or concrete to rocky surface , bonding to
smooth surface
is poor. To
enchance bonding
between such
matrix additional
bonding aid
is necessary. Anchorex
is an admixture
which enchances
bonding features
as well as bonding strength.
Ideal for making up jobs and gunniting.
Anchorex
is milky white liquid. It is used in proportion
of 2%
- 5%
to the weight of cement used
for gunniting application. That is in case one bag of cement is intended to be
used 1 - 2½ litres of Anchorex
is required.
Its proportion
can be
increased depending
on the
bonding strength
required and its
application. For instant grab bonding more than 5% may be used.
Prepare
dry cement
mortar using
required quantity
of cement and aggregate. Mix
thoroughly. Mix Anchorex to
the gauging
water and
add this water
to the dry cement mortar. Usually water cement
ratio of 0.5 to 0.6 is used. Anchorex is added to the gauging water
keeping water cement ratio 0.5 to 0.6.
To enchance bonding further, mix Anchorex and water in the ratio 1 : 10 and coat the entire surface with this Anchorex-water-primer. Apply the fresh mortar or concrete when the Anchorex-water-primer is still wet and tacky.
To
prepare priming cement slurry for bonding
on difficult
to bond surface prepare cement slurry using Water + Anchorex in the proportion
20 : 1 to 10 : 1. Add cement
as required
to bring
it to suitable consistency, i.e. either brushable consistency, or
sprayable consistency. This Anchorex-water-primer enchances
the bonding action & also the grabbing power of the mortar which is
to bond on the treated surface.
Anchorex
can
also
be
used
for
rehabilitation
&
repairs
of
RCC
members
where
the steel bars are exposed or where cover to reinforcement is lost, due
to chemical corrosion or due to saline corrosion.
To
prepare Anchorex-water-primer using Anchorex, water & cement.
Mix Anchorex with water in the proportion 1 : 10. Take 3 ltr. of
Anchorex–water-primer & add 3 kgs cement. Mix
thoroughly to bring it to brushable
consistency.
Scrub
the exposed surface with wire brush to remove all loose
material,
algae ,
bacterial cover etc. Hack surface if necessary to remove all loose
material. Brush apply Anchorex priming slurry.
Prepare
cement , sand
and
grit mortar using 1 part cement + 2 part
sand + 3 part
5 mm grits. Mix water + Anchorex in the proportion 20:1. Use water
Anchorex preparation 20 : 1 in the proportion 0.4 to 0.5
as water cement
ratio. Make up the entire cover lost on steel reinforcement with this
material. This
material must be used whilst the Anchorex priming slurry which is brush
coated is still wet & tacky.
For repairs
plaster use Anchorex-water-primer and water in the proportion 1 : 1, add this
slurry to cement and sand (1:4).
Mix thoroughly.
Prepare
surface by
thorough wire
brush scrubbing; remove all
loose material, clean surface
from algae or
bacterial cover.
Apply one
coat of Anchorex-water-primer
or Anchorex priming slurry. The later may be used if the throw back is high in
case of ceiling repairs etc.
For
gunniting application use 1 ltr to 2.5 ltr Anchorex per bag of cement
