Key Features and Benefits
High Strength
BASF Masterflow 718 provides both impressive early and ultimate strengths, ensuring quick return to service and long-term durability. With compressive strengths reaching up to 65 N/mm2 after 28 days, this product is an ideal choice for heavy-duty applications .
Non-shrink
When used at flowable consistency, Masterflow 718 hardens without bleeding, settling, or drying shrinkage. This non-shrink property ensures that the grout maintains its volume and integrity throughout the curing process .
Flowable Consistency
The flowable consistency of Masterflow 718 ensures complete filling of even intricate voids, often without the need for pumping and strapping . This characteristic makes it easier to apply and more effective in filling gaps and securing structural elements.
Ample Working Time
Masterflow 718 offers an extended working life, remaining placeable for up to 1 hour even at high ambient temperatures . This ample working time allows for greater flexibility during application and ensures a proper and secure installation .
Dense, Impermeable Grout
This grout provides a dense , impermeable seal that is watertight, protecting structures from water infiltration and potential damage .
Economical
Masterflow 718 is an economical choice, as greater volumes of grout can be mixed and handled with less labor. It does not require any special mixing equipment and can be mixed in a pail using a grout stirrer .
Easy to Use
Masterflow 718 is user-friendly, requiring no special mixing equipment. It can be mixed using a hand drill and paddle for small works up to two bags at a time or specialized grout mixers for larger volumes .
Recommended Uses
Masterflow 718 is recommended for various applications, including :
Properties
BASF Masterflow 718 offers several desirable properties, such as :
Application
To achieve a flowable or trowelable consistency, add MasterFlow 718. . The quantity of water required to produce a flowable grout from a 25 kg bag is approximately 4.0 liters. Water addition may be affected by temperature conditions on site; it is recommended to perform trials to determine the correct water requirement .
For optimal mixing efficiency, use a suitable mixer. Hand drills and paddles can be used for small works up to two bags at a time, while specialized grout mixers are recommended for larger volumes. After the grout is smooth and lump-free, add the appropriate amount of water to the mixer, then add the powder (usually between 3 – 5 minutes) .
For best results, use MasterFlow 718 within 30 minutes of mixing. Ensure the substrate is properly prepared, free from contamination, laitance, and loose material. Prior to applying the grout, properly wet the substrate for at least two to three hours and remove any free water ponding .
Curing is essential to prevent rapid drying and shrinkage. Use accepted methods such as curing compounds, polythene sheets, wet hessian, or water ponding. If a shaped shoulder is required , form it before the grout has reached its final set, removing the formwork once MasterFlow 718 is self-supporting.
Cleaning and Maintenance
Clean tools and equipment with water before MasterFlow 718 hardens; otherwise, mechanical cleaning will be required .
Estimating Data and Packaging
A 25 kg bag of MasterFlow 718, when mixed to a flowable consistency (adding 4.0 liters of water), yields 13.2 liters of grout . The product is packaged in 25 kg moisture-resistant bags .
Precautions and Safety Measures
Consult the Material Safety Data Sheet (MSDS) for the product, which BASF provides or is accessible on their website, for comprehensive health, safety, and environmental advice.
Conclusion
BASF Masterflow 718 is a versatile, high-performance, non-shrink cementitious grout designed for use in a wide range of civil engineering applications . Its key features and benefits, such as high strength, non-shrink properties, flowable consistency, ample working time, and ease of use, make it a top choice for numerous projects . Always follow proper application and safety procedures to ensure optimal results and safety during use .
