POLYGROUT MC

 

 Product  Descreiption 

POLYGROUT-MC is ready to use cement based compound, which requires only addition of water to produce high performance free flowing, non-shrink micro-concrete.

                                                 

Typical Application

 

POLYGROUT-MC is formulated from applications where micro concrete is needed to be pumped or poured into restricted spaces. Typical applications include grouting, bedding for the following:

  • Structural elements such as recast walls,

                beams & columns.

  • Milling equipment.
  • Gas & steam turbines.
  • Crane rails.
  • Filling voids around doorframes, recast

                walls & panels.

·         Narrow or confined areas in concrete

                structures.

·         Reinstatement of damaged, affected concrete

                by partial or total replacement.

·         Anchor bolts.

·         It is recommended to be used for

sections       exceeding 60mm.

 

Product Features

     

  • Fiber reinforced cementations grout, with none staining.
  • Easy to use, just requires the on-site addition 

                of water.

  • Excellent flow ability, which facilitates   

                complete filling of narrow voids.

  • Shrinkage compensated system.
  • Contains special graded hard inert aggregates

                which enhance pump ability reduces

                segregation.

  • High bond strength to steel as well as

                concrete .

  • Durable concrete with low permeability.
  • Carbonation & chloride ingress resistant.   
  • Excellent thermal compatibility with the

               concrete substrate .

·         Provides early strength development. 

·         Formulated to be suitable for the Middle 

                east conditions.

Guide for Applications

 

Surface Preparation

 

The surfaces should be clean, sound, free from oil & grease and contaminants.

 

Mixing

 

The exact amount of water added to the pre-mixed powder in a quantity sufficient to achieve the required consistency.

 

Plastic Mix Consistency

 

3.5    lit. /25 kg bag

 

Foldable Mix Consistency

 

4.75        Lit. /25  kg bag.

Use clean, potable water for mixing. Place carefully the measured water into the mixing container, and then add

Powder gradually. Use a mechanical mixer of low speed drill, mix for approximately 5 minutes until a smooth even consistency is achieved.

It is not recommended to mix more than what can be placed in 60 mm. and no remembering (Adding water) to restore workability.

 

Placement

 

Flow able grout should be placed continuously from one side, avoiding the entrapment of air pockets.

 

 

 

Provide vent holes for large base plates. Voids should be removed rodding, strapping or vibrating, (avoid excess vibration).

 

Yield

 

12.7-13  liters/25 kg (bag) depending upon consistency achieved.

78 bags after mixing with water will yield one cubic meter.

 

Curing

 

After placement, keep exposed surface damp. Cure grout at least three days by applying a membrane curing compound such as POLYCURE WBI (See separate data sheet).

Protect the placed micro concrete from extreme heat or cold &drying for at least 3 days.

 

Cleaning

 

Clean all the tools and the equipments immediately after use with clean water.

 

Packaging

 

POLYGROUT-MC is supplied in 25 kg well sealed bag.

 

Shelf Life

12 months when stored as recommended.

 

Storage

 

It should be kept in dry warehouse away from any source of moisture.
