This
material is not affected by chemical attack or carbonation |
 |
Unlike
epoxy mortar it will not create isolated pockets of very high
strength as compared to existing old concrete. |
 |
It
is more economical and more user friendly than epoxy when large
areas are to be rehabilitated. Cost reduction would be around 33% as
compared to epoxy mortar. |
 |
Polymer
mortars and concrete have fire resistant characteristics similar to
that of normal concrete while epoxy mortars can catch fire. |
 |
Polymer
solution and cement are easily miscible. |
 |
In
addition to creating a strong physical barrier to prevent chemical
attacks it can also mitigate corrosion due to its alkaline nature. |
 |
Polymer
emulsion in repair concrete. It relieves the internal micro
stresses, retards formation and enlargements of cracks and increases
the overall strength of concrete. |
 |
Polymer
helps to block the voids and seal the cracks and thereby
substantially reduces the ingress of moisture and chemicals. |
 |
Thickness
of polymer mortar of the order of 10 to 15 mm over the steel is
adequate enough to give excellent protective cover and therefore the
balance thickness can be made up with well-controlled plain mortar.
Curing plays a relatively less important role in cases where polymer
is used. |
