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.
