Uses of Fosroc Conbextra EP300
Fosroc Conbextra EP300 is an ideal solution for various applications in the construction industry , including :

1. Grouting under heavy equipment: The product is suitable for use where heavy, dynamic, or mobile loads are encountered. It ensures a stable and secure foundation for equipment such as reciprocating or rotating machinery .
2. Supporting crane rails: Conbextra EP300 provides a strong , long-lasting bond for heavy crane and transporter rails, ensuring that these rails remain stable and secure during operation.
3. High-speed turbine and centrifuge stabilisation Conbextra EP300 is a great option for grouting under high-speed turbines and centrifuges because of its strong compressive, tensile, and flexural strengths, assuring the safe and effective operation of these devices .

Advantages of Fosroc Conbextra EP300
Some of the key benefits of using Fosroc Conbextra EP300 include :

1. Low creep characteristics: Conbextra EP300 exhibits low creep under sustained loading, ensuring that the grout maintains its integrity and stability over time .
2. 2. Resistance to dynamic loads: The product's superior performance in resisting dynamic loads makes it ideal for use in heavy equipment installations, where constant movement and vibrations are common .

1. Non-shrink properties: Conbextra EP300 is formulated to be non-shrink, ensuring that it maintains its volume once cured. This feature is vital in providing a secure bond between the grouted equipment and its foundation.
2. High strength: The epoxy resin-based grout boasts high compressive, tensile, and flexural strengths, making it suitable for use in various demanding applications .
3. Chemical resistance: Conbextra EP300 is resistant to a wide range of chemicals, including alkalis, most acids, and petroleum-based products, making it suitable for use in harsh environments .

Technical Support
Fosroc and its authorized distributor, Space Arc Engineering, provide comprehensive technical support to assist customers in the correct application of Conbextra EP300 . Their team of experts is available to guide customers in product selection , surface preparation, and application procedures .

Application Process

1. Surface preparation: Proper surface preparation is crucial for achieving a strong bond between the grout and the substrate . Surfaces must be clean, free from dust, debris , and any contaminants that may impair adhesion. It may be necessary to roughen smooth surfaces to improve the bond.
2. Mixing: The three components of Conbextra EP300 (base resin, liquid hardener , and inert fillers) must be thoroughly mixed according to the manufacturer's instructions to achieve the desired consistency and performance .
3. Placing: Once mixed, the grout should be placed immediately, ensuring that it flows freely into the gap and completely fills the void. It is essential to minimize the time between mixing and placing to prevent premature curing .

Estimating and Storage
Proper estimation of the required quantity of Conbextra EP300 ensures cost-effective use of the product . Storage is equally important; the product should be stored in a cool , dry place away from direct sunlight, and within the recommended temperature range . Ensure that the containers are sealed when not in use to prevent contamination and degradation .

Always wear appropriate personal protective equipment (PPE) , such as gloves , goggles, and a dust mask when handling the product . Follow the manufacturer's guidelines and safety data sheet for additional information on safe handling and disposal .

Conclusion
Fosroc Conbextra EP300 is a versatile and high-performance epoxy grout that provides a strong , stable foundation for a wide range of applications in the construction industry . With its numerous benefits, such as high strength, chemical resistance, and low creep characteristics, it has become an essential product for engineers and contractors alike .

FAQs

1. What is the maximum gap that can be grouted with Fosroc Conbextra EP300?
   Fosroc Conbextra EP300 is suitable for grouting gaps ranging from approximately 10 to 300 mm .
2. Can Conbextra EP300 be used in underwater applications?
   No, Conbextra EP300 is not designed for underwater applications. It is best suited for use in dry conditions .
3. What is the pot life of the mixed grout?
   The pot life of the mixed grout depends on the ambient temperature. At 25°C, it is approximately 45 minutes. The pot life decreases as the temperature increases .
4. How long does it take for Conbextra EP300 to cure?
   The curing time for Conbextra EP300 depends on the ambient temperature and the specific application. Under normal conditions, it reaches its initial set in about 6-8 hours at 25°C. Full cure is typically achieved in 7 days .
5. Is Fosroc Conbextra EP300 suitable for both indoor and outdoor applications?
   Yes, Conbextra EP300 is suitable for both indoor and outdoor applications. However, it is important to consider the environmental conditions and ensure that the product is protected from moisture and extreme temperatures during the application process .
