Hind HSMC is used for repairs to damaged reinforced concrete members, for cover replacing concrete, resistance to weathering action, and places where free flow concrete is required to be placed and vibration is difficult. Most suitable for structural repairs of columns, beams by means of encasement, jacketing etc.
The surface of old concrete member should be properly prepared by chipping off all the loose concrete, exposed reinforcements should be cleaned and de-rusted manually or mechanically, anticorrosive coating of acrylic or epoxy base like Hind Anti Rust or Hind Anti Rust EZ to be applied on the de-rusted reinforcement, bonding coat based on Epoxy or Polymer latex like Hind Bond EBA or Hind Styrene BR to be applied on the surface of concrete, steel or plywood shuttering to be fixed within the time the bonding coat becomes tacky and does not set.
The micro concrete to be mixed in the ratio of 1:0.5 to1:0.75 (1 part powder of micro concrete chemical : 0.5 to 0.75, 12 mm down silt free stone aggregate) with a Water : Powder ratio of 0.21 .The micro concrete chemical and the coarse aggregate is to be dry mixed thoroughly first and then it is to be slowly poured in pre measured water in a mixing container and stirred thoroughly manually or by a power paddle to obtain a free flow uniform pourable mix.
The mixed material is then poured manually or pumped into the gap between the concrete members and shuttering to get a self compacted screen concrete of thickness between 40mm to 125mm.No vibration is required except gentle tamping by a light weight tool.
