Properties:

INDUGROUT-MC 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 grouting mortar for large gap filling. INDUGROUT-MC contains selected Portland cements, selected hard aggregates, modifiers and shrinkage-compensating materials that work during both the plastic & post hardened states. INDUGROUT-MC is designed for application by pouring or pumping in thicknesses between 12 mm & 300 mm.

Areas of Application:

INDUGROUT-MC 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.
Non-oxidized, non-shrink.
Low heat of hydration.
Compatible with all physical properties of concrete.
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.
Can be applied in a single layer at a thickness of up to 300 mm.

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 1 & 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-MC. Steel reinforcement must be grit blasted to SA 2&1⁄2 (white clean metal) and immediately primed with INDUBOND-VK4032-ACI or INDUCRET-BIS-0/2 before new rust/scale is formed. Please refer to relevant technical data sheets.

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.
70 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.
