Description USES MFlow 648 is ideal for a wide range of high-strength grouting and fixing applications, including but not limited to: Fixing of starter bars and anchor bolts Grouting and securing of machinery, including heavy equipment and precision machines Under-grouting for base plates and machine foundations, including heavy-duty machinery Fixing of crane rails and light rail tracks Bedding of structural components and precast elements Grouting for bridge bearings, mechanical joints, and foundation elements Suitable for use in tunnels, over bridges, and other infrastructure projects where durability and high impact resistance are required. FEATURES High early strength: Provides fast setting and early strength development. Flowable consistency: Ensures easy application and good flow into tight spaces. Non-shrink: Maintains the grout’s integrity without shrinking over time. High bond strength: Excellent adhesion to steel, concrete, and other construction materials. Corrosion and chemical resistance: Durable in harsh environments. Vibration and impact resistance: Effective in applications with machinery or structures subject to constant movement or stress. Thermal expansion compatibility: Low coefficient of thermal expansion, reducing the risk of cracks. Moisture resistant: Suitable for wet and humid environments, maintaining performance in difficult conditions. PRODUCT INFORMATION Composition: Epoxy resin with selected fillers and aggregates Packaging: Supplied in 30 kg pre-measured kits (Part A Part B Part C) Shelf Life: 12 months from the production date when stored in ideal conditions Storage Conditions: Store in a dry, cool, and well-ventilated area between 5°C and 30°C. Keep containers sealed and protect from moisture, direct sunlight, and excessive heat. Appearance and Color: Grey or as specified Density: Approximately 1.85 kg/l (mixed at 25°C) TECHNICAL INFORMATION Compressive strength: ≥ 90 N/mm² (7 days at 25°C) (ASTM C579, BS 6319) Flexural strength: ≥ 30 N/mm² (7 days at 25°C) (ASTM C580) Tensile strength: ≥ 12 N/mm² (7 days at 25°C) (BS 6319) Coefficient of thermal expansion: ~4.8 x 10⁻⁵/°C (ASTM C531) Effective bearing area: ≥ 85% (ASTM C1339) Working temperature range: Applied at temperatures between 5°C and 40°C Pot life: At 25°C: ~45 minutes At 40°C: ~25 minutes APPLICATION INFORMATION Layer Thickness: Minimum grout depth: 20 mm Maximum grout depth: 80 mm Ambient Temperature: Minimum: 20°C / Maximum: 40°C Substrate Temperature: Minimum: 15°C / Maximum: 40°C Substrate Moisture Content: ≤ 4% for optimal adhesion and grout performance Dew Point: Ensure substrate temperature is at least 3°C above the dew point to avoid condensation during application. Application Method: Use a mechanical mixer to ensure thorough blending. Add water to achieve the desired consistency and ensure a smooth, lump-free mixture. Apply immediately after mixing to ensure optimal performance. Curing Time: Full curing occurs within 7 days at 25°C. Low temperatures may extend curing times.
