Maxcrete 651 Non-Shrink Patching Grout: Product Information and Application Guidelines

Description:

Maxcrete 651 is a high-strength grout composed of high-quality Portland cement, graded natural aggregate, and shrinkage compensating additives. It requires only the addition of water to form a stiff grout with plastic consistency, making it suitable for molding into shapes and patching cavities without the need for formwork support.

Features:

• Requires only the addition of water.
• Stiff consistency eliminates the need for formwork support in vertical applications.
• No bleeding.
• High early and ultimate strength.
• Good dimensional stability.
• Impact and vibration resistant.
• Chloride and iron-free, non-toxic, and non-corrosive.

Uses:

• Repairing chips in columns and walls.
• Patching holes, voids, and cavities.
• Floor topping.
• Nosing edges.
• Anchor bolts.
• Forming fillets and chamfers.
• Other non-shrinkage filling requirements.
• Suitable for high-strength applications.

Mixing Instructions

• Maxcrete 651: 25 kg
• Clean Water: 4.25 liters

1. Pour 4.0 liters of water into the mixing container.
2. Slowly add Maxcrete 651 powder while stirring with an electrical mixer at 500 rpm.
3. Adjust to the desired consistency by adding part portion of 0.25-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.

Grout Placement:

• Holes, Voids & Cavities: Compact the freshly mixed grout into the repair area and finish with a steel trowel. Apply only up to 20mm thickness per layer when using Maxcrete 651 without the addition of aggregate.
• Large Cavity/Volume: Add aggregate to prevent over-heating. Use cold water to mix the grout during the initial cure.
• Floor Topping: Premix sand with Maxcrete 651 and diluted Maxcrete Latex for floor topping applications.

Curing, Storage & Shelf Life

• Protect from strong sunlight and high windy conditions 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.
