INDUGROUT-PH

High performance, high strength, non-shrink, non-oxidized, post-hardening, cementitious grout

Properties:

INDUGROUT-PH is a ready-to-use high performance, high strength, non-oxidized, non-shrink, cementitious grout which only requires the addition of water to produce a non-shrink flowable mortar. INDUGROUT-PH contains a blend of selected Portland cements, special aggregates, modifiers and shrinkage compensating materials that work during both the plastic & post hardened states. INDUGROUT-PH is designed for application by pouring or pumping in thicknesses between 10 mm & 80 mm. INDUGROUT-PH does not release any gases during its plastic or hardened states.

Areas of Application:

INDUGROUT-PH is typically used for:

  • Grouting anchor bolts.
  • Grouting bridge bearings.
  • Grouting of structural elements such as precast wall, beams, columns, etc.
  • Grouting anchor bolts, crane rails and milling machines.
  • Structural concrete repairs.
  • Grouting of generators & turbines.
  • Heavy stanchion bases and base plates of reciprocating machines.

Advantages:

  • Easy to mix and apply.
  • Designed for hot weather applications.
  • Nor-oxidized, non-shrink.
  • Does not contain gas releasing agents.
  • Resistant to water and water-borne salts.
  • Adjustable consistency.
  • High mechanical properties.
  • Low permeability extends durability & service life.
  • High early and ultimate strengths.
  • Chloride-free, nitrate-free & non-toxic.
  • Excellent bond to concrete and steel.
  • Excellent heat resistance.

Product Details

Product Preparation:

Surface Preparation

All surfaces must be sound, clean and free from dust, grease, oils, curing compounds, mould release agents or other adhesion inhibiting materials. Remove all surface laitance and maintain a surface profile between CSP | & CSP 5 as described by the International Concrete Repair Institute (ICRI). Thoroughly saturate all mineral substrates and remove standing/surface water prior to application of INDUGROUT-PH. Steel reinforcement must be grit blasted to SA 2&2 (white clean metal) and immediately primed with INDUBOND-VK4032-ACI or INDUCRET-BIS-0/2 before new rust/scale is formed.

Product Shuttering:

Shuttering

Always use water tight and smooth surfaced shuttering. Use rubber strips or appropriate sealant between the formwork and the host concrete. Maintain a maximum unrestrained (exposed) gap between the formwork and base plate edge of:

25 mm on inspection sides.

7O mm on pouring side.

Product Mixing:

Mixing

Place the exact amount of water in a clean vessel and gradually add the contents of the bag while mixing with an electric drill (maximum 450 rpm) attached with the appropriate mixing paddle. Continue mixing until a homogenous, lump-free consistency is achieved. An appropriate grout mixer is recommended for large- volume grout pours. DO NOT mix more than what you can consume within 45 minutes at +25 °C. DO NOT RE-TEMPER grout to restore workability. Grouts that have lost workability must not be used.
