Maxcrete 650 Self-Leveling Mortar

TECHNICAL SPECIFICATIONS

APPLICATIONS

Thanks to its high strength, excellent dimensional stability, and resistance to vibration and impact, Maxcrete 650 is widely used in the following applications:

• Filling concrete holes and voids – repairing structural defects.

• Grouting machine bases and rail tracks – withstanding dynamic loads and vibrations.

• Grouting base plates – creating a solid foundation for industrial equipment.

• Anchoring bolts – precisely fixing bolt positions in concrete.

• Grouting columns in precast concrete structures – connecting components.

• Filling gaps between precast concrete components.

• Grouting pipe sleeves – protecting and reinforcing pipes passing through floors/walls.

• Other patching and high-strength applications.

INSTALLATION GUIDE

🔹 Surface Preparation

• The concrete surface must be clean, sound, free from impurities, cement dust, or grease.

• Steel surfaces must be cleaned of rust scales and grease.

• Absorbent surfaces should be thoroughly pre-wetted before application, but no standing water should remain.

• Erect formwork (if necessary) to ensure it is watertight, sturdy, and can withstand the pressure of the mortar.

🔹 Mixing Ratio

• 25 kg Maxcrete 650 + 3.25 – 3.50 liters of clean water.

• Pour approximately 3 liters of water into a clean mixing drum.

• Slowly add Maxcrete 650 powder while stirring with a mixer at 500 rpm.

• Adjust by adding a maximum of 0.5 liters of water to achieve the desired consistency.

• Mix for approximately 3 minutes until the mixture is homogeneous, smooth, and lump-free.

📌 For large holes/voids: Aggregates (clean 1×2 stones) can be added at a ratio of 50 – 100% of Maxcrete 650 powder weight to reduce heat generation. Aggregates should not be larger than 30mm and not exceed 1/3 of the minimum gap thickness. Cold water should be used for mixing when working with large volumes.

🔹 Application

• Pour/pump the mortar immediately after mixing, applying continuously to avoid cold joints.

• Pour into a single point to increase flow pressure, helping the mortar spread and fill all voids.

• Use a steel rod or stick to release air bubbles and ensure all voids are filled.

• For base plates: Erect watertight formwork, soak with water overnight, remove all standing water, prepare sufficient mortar, and pour continuously from one side.

• For machine bases/rail tracks: Remove standing water and mortar residue from anchor points, then continuously pump the grout.

🔹 Curing

• Cover the newly applied area immediately after the mortar sets.

• Keep moist with wet burlap or curing membrane for a minimum of 3 days to prevent rapid drying of the mortar and ensure optimal strength development.
