MasterFlow Grout 1205

MasterFlow Grout 1205 is a high-performance, cement-based grout designed for a range of demanding construction applications. It features specially graded aggregate that ensures a pumpable, non-bleeding, and fluid product with high strength and an extended working time. MasterFlow Grout 1205 is engineered to meet all ASTM C 1107 requirements at a fluid consistency, making it ideal for projects requiring precise, high-quality grouting solutions.

– Superior Pumpability: Easily pumped over long distances through small openings due to its specially graded spherical aggregate, which also helps mitigate chloride migration.

– Extended Working Time: Allows for flexibility during application with a minimum of one hour of pumpability at 90°F.

– High Strength: Achieves high compressive strength without bleeding, settlement, segregation, shrinkage, or formation of voids.

– Durability: Features an integral corrosion inhibitor that adds protection to embedded steel reinforcement, enhancing the longevity of the structure.

– Post-Tensioned Structures: Ensures effective encapsulation of post-tensioned tendons, cables, and high-strength rods, protecting them from corrosion.

– Structural Voids: Suitable for filling voids in restricted spaces where the grout will contact highly stressed steel, such as between wall panels, beams, and columns.

– Cable Anchor Plates: Perfect for grouting cable anchor-plates or other plates where grout will contact highly stressed anchorages.

MasterFlow Grout 1205 should be mixed with 1.8 to 2.1 gallons of water per 55 lb bag, adjusting the water content as needed based on job conditions. It is critical to mix until the grout is homogeneous and free of lumps. The product should be applied using a colloidal mixer for best results, ensuring that the mix is consistent and free of clumps before pumping.

Packaged in 55 lb bags and 2,500 lb bulk bags, MasterFlow Grout 1205 has a shelf life of 6 months for bags and 3 months for bulk bags when stored properly in cool, dry conditions.

MasterFlow Grout 1205 represents a state-of-the-art solution for complex grouting applications in construction, delivering both performance and ease of use in a range of environmental conditions.
