• One of the most versatile and broadly utilized
  construction materials is RCC. It is because of
  its mouldability and designable durability. A
  concrete structure is only durable if it can
  resist exposure beyond its service life with a
  slight worsening. The strength and performance
  of concrete structures have been profoundly
  affected because of the severe pollution and
  excessive demand for construction. However, there
  are various techniques available for repair and
  rehabilitation of concrete structures in case of
  defects and damages. Have a look at the following
  mentioned information that explains the causes of
  defects in concrete and also the repair
  techniques.

Surface Treatment

• If we apply solutions of sodium silicate,
  magnesium, or zinc sulfates or silicofluorides,
  the surface of the hardened and dry concrete can
  be made less dust-generating and
  abrasion-resistant. Linseed oil or Tung oil are
  drying oils that can also be used. Paints
  containing synthetic resins, particularly
  polyurethanes or epoxies, offer excellent
  resistance to wear, and also protect against
  solutions of salts and dilute acids. In mild
  conditions of aqueous solutions or organic
  liquids, sodium silicate and silicofluoride
  applications also aid in protection. For
  protection against borers and insects, coal
  bitumen can be used. For improving concrete's
  durability, PVC linings, rubber latex glass-fiber
  coatings, and some plastic materials can also be
  used.

Epoxy Resin Grouting              

• Epoxy resin, when cured with different hardeners,
  offers a broad range of properties such as low
  shrinkage, high adhesive strength, natural gap
  filling, thermosetting, etc. Repair of reinforced
  concrete structures can be done using epoxy resin
  grouting, and the following is the procedure for
  the same
• The first step is to locate the cracks and clean
  that surface
• Next is, using epoxy putty, frequent drilling and
  fixing of nozzles for grouting has to be done
• Lastly, using a grout pump, we need to grout the
  epoxy mixture and seal the vents through which
  grouting is done

Steel Fiber Reinforced Concrete

• According to the statistics, for improving many
  properties of concrete, such as impact wear
  resistance, tensile strength, etc., we can use
  minute diameter steel fibers in concrete.
  Firstly, the damaged portions of a concrete
  structure are removed, and steel fiber reinforced
  concrete is placed to the sides and bottom of
  defective materials. For repairing floors and
  bridges, steel fiber RC can be used with or
  without polymer concrete. Your ultimate
  destination for the repair of reinforced concrete
  structures is here at Cortec Me. Get the best and
