DUROCON 750

DUROCON 750 is a single component polymer modified re-profiling mortar for use as a repair cosmetic mortar. It is specially formulated to produce a shrinkage compensating mortar with no cracking when applied in a thin section. Adhesion to concrete and flexibility are excellent.

 

Specification

The high performance re-profiling mortar shall be DUROCON 750, a single component polymer modified mortar which can be applied at 3 mm thickness without any need of primer. The product shall exceed compressive strength of 200 kg/cm2 at 28 days and shall have adhesive bond strength to concrete in excess of 10 Kg/cm2, when tested to ASTM D4541 test method.

Uses 

  • As a repaire in concrete surfaces such as honeycombing, blowholes, defects caused by 'sand runs', patch repairs, shutter movement and grout loss.
  • To repair concrete within cover zone.
  • Preparatory treatment to concrete to receive a thin film protective coating.
  • To produce a uniform surface over repaired areas.

Advantages 

  • Shrinkage compensating.
  • Excellent adhesion to concrete.
  • Subsequent paint coats can be applied with greater economy.
  • Flexible, resistant to cracking, smooth, easily produced finish.
  • Low permeability, excellent resistance to freeze / thaw action and carbonation.
  • Precision made consistent performance.
  • Requires only the addition of mixing water.
  • Ingress of water borne salts, such as chloride and atmospheric / chemical attack.
