• Requires only the addition of water with adjustable consistency.
• Pourable or placed with a suitable grout pump.
• Excellent flow-ability and self-leveling properties.
• Able to fill intricate voids.
• High early and ultimate strength.
• Good dimensional stability with no bleeding.
• Impact and vibration resistant.
• Chloride and iron-free, non-toxic, and non-corrosive.
• Extended pot life.

Uses:

• Filling of honeycomb and cavities.
• Machine foundation and rail beds.
• Under-plate applications.
• Anchor bolts.

• Clean Water: 3.25 – 3.50 liters

1. Pour 3.0 liters of water into the mixing container.
2. Slowly add Maxcrete 650 powder while stirring with an electrical mixer at 500 rpm.
3. Adjust to the desired consistency by adding part portion of 0.5-liter water.
4. Mix for 3 minutes until a lump-free, homogenous consistency is achieved.

Application Guidelines

Substrate Preparation:

• Concrete surfaces must be clean, sound, and free from contaminants, laitance, and loose particles.
• Iron and steel surfaces should be free from scale, rust, oil, and grease.
• Absorbent substrates must be thoroughly saturated, leaving no standing water before grout placement.
• Erect formwork if necessary, ensuring a well-braced, strong, and watertight construction.

Grout Placement:

• Maxcrete 650 grout should be pumped or poured into place upon mixing.
• Fill continuously onto a single point to promote flow and avoid entrapping air.
• Use a steel rod or chain to ensure all cavities are filled.

Special Applications:

• Under-plate: Construct a strong and watertight formwork, flood the area overnight, leave no standing water, and fill only from one side.
• Machine Foundation & Rail Beds: Remove standing water from bolt holes, pour the foundation bed in the second operation with uninterrupted grout flow.
• Large Cavity/Volume: Add aggregate to prevent over-heating, and use cold water to mix the grout.

Curing, Storage & Shelf Life

• Protect from strong sunlight and high wind during curing; keep moist for the next 3 days.
• Keep elevated in a dry, moisture-free condition; can be stored for 12 months in sealed original packaging.

Health & Safety

• Prevent contact with skin and wear waterproof gloves and goggles when handling.
• Upon contact with skin, wash with soap and water.
• In case of eye contact, flush with water and seek medical attention immediately.
