POLYCRETE
This ready-mix micro-concrete
is tailored for easy application wherever access to the repair material is
limited. On mixing with water alone this turns to an easily flowable and
cohesive mix. On use it finds its way into the crevices and recesses which
normal concrete cannot easily enter. Formulated from a blend of Portland Cement
and graded aggregate and other ingredients this product has several special
characteristics.
Uses
Eminently suitable for repairs
of structural slabs columns and beams. Whenever repairs are to be carried out,
like structures in distress, leaky water tanks, machine foundations etc. this
product is suitable. It can be used to replace damaged members also.
Advantages
In fresh state: cohesive &
flowing
In hardened state: non-shrink,
good bond, compact & dense
Forms good bond with old
concrete; provides an excellent finished surface in contact with the formwork.
Properties
The product is available in two
different grades. POLYCRETE A is suitable where high early strength is required
where there is only a limited time for carrying out the repairs.
Otherwise POLYCRETE B could be
used.
The strength increases with age
and in the presence of water.

Instruction for use
Use 12.5% of water by weight of
POLYCRETE and mix thoroughly in a bucket until it forms a mix of uniform and
flowable consistency. Normally 2 to 3 minutes of mixing is adequate. Use ice
cold water in hot weather. The mix is ready for use. Mix only that much
quantity which can be consumed in about twenty to thirty minutes.
Yield
25 kg polycrete yield 12.5
ltrs.
Curing
This material is designed to
achieve adequate properties in just 3 days after placement. Hence cure for this
duration would be adequate for most practical purpose.
Packing
25 kg bag.
Shelf life
Six months when stored in
original packing.
