Mapei Mapefill 318 Pumpable, Multi-Purpose, Shrinkage-Compensated, Cementitious Grout 25KG
- Brand MAPEI
- Model: MP-MPF318-25
Description
• Mapefill 318 is a preblended powdered grout composed of high strength cement, graded 1.2 mm aggregates and special additives with expansion agents formulated by the MAPEI research laboratories.
• When mixed with water, Mapefill 318 is transformed into a highly fluid grout with good pumping properties that able to fill narrow, intricate spaces without segregation.
• Mapefill 318, due to its dual-stage expansion, is characterized by a total absence of shrinkage in the plastic and hardening phases, and develops very high early flexural and compressive strengths. Mapefill 318 also has the following qualities:
- excellent impermeability to water;
- excellent adhesion to steel and concrete;
- excellent resistance to dynamic mechanical stress;
- modulus of elasticity and thermal expansion coefficient similar to those of high quality concrete.
• Mapefill 318 meets all the main requirements defined by EN 1504-9 (“Products and systems for the protection and repair of concrete structures; definitions, requirements, quality control and conformity assessment. General principles for the use of products and systems”) and the minimum requirements claimed by EN 1504- 6 (“Anchoring steel reinforcement”).
Features
• Non-Shrink: It has a non-shrink formula, which ensures that the grout remains stable after curing, maintaining contact with surrounding surfaces and filling gaps without shrinking.
• High Early and Final Strength: MAPEFILL 318 achieves high early compressive strength, making it suitable for fast-track projects where early load-bearing capacity is essential. It also reaches very high final strength.
• Flowable Consistency: The grout has a flowable and self-leveling consistency, making it easy to apply and ensuring it fills cavities and voids without the need for extensive vibration.
• Versatile Usage: Suitable for a wide range of applications, including the grouting of machine bases, anchor bolts, steel structures, and other structural elements that need high strength and durability.
• Excellent Bonding: MAPEFILL 318 offers strong adhesion to steel and concrete surfaces, ensuring a reliable bond that enhances the stability and longevity of structures.
• Chloride-Free: The formulation is chloride-free, which helps prevent corrosion of steel reinforcements or anchors within the grout, ensuring durability and suitability for long-term applications.
• Consistency Options: MAPEFILL 318 can be mixed with different water ratios to achieve either flowable or plastic consistency, depending on project requirements.
• Easy Application: It can be poured easily and is suitable for both horizontal and vertical applications, making it convenient for various construction needs.
• Resistance to Dynamic Loads: Ideal for settings where the structure will experience vibrational or dynamic loads, such as machinery bases and heavy-duty equipment installations.
• Packaging: Mapefill 318 is available in 25 kg bags.
• Storage: Store in a dry, sheltered place in original, unopened packaging for 12 months.
