Gibco's M.R.F is a chloride-free performance admixture for masonry. It replaces traditional lime with a user-friendly formula. Gibco's MRF is engineered to enhance standard cement, transforming it into high-quality mortars suitable for masonry applications. Laboratory tests comparing MRF with cement-lime mortars have demonstrated that it outperforms them in both plastic and hardened state properties. These tests include:
- Air content measurement
- Water retention evaluation
- Setting time assessment
- Compressive strength testing
- Freeze-thaw resistance analysis
- Sulfate resistance inspection
- Drying shrinkage examination
- Autoclave expansion testing
- Flexural bond strength measurement
The plasticizing properties of Gibco's MRF make it an effective alternative to lime, clay, and other plasticizers, resulting in significant cost savings, as 5 liters of it can replace up to 45 bags (900KG) of lime. Whether you're working with block, brick, or stone, MRF is capable of completing the entire task.
PLASTIC PROPERTIES:
- Extends board lifespan and setting duration
- Produces a uniform gel-like consistency
- Improves ease of work
- Enhances adhesion capabilities
- Reduces water requirements
HARDENED PROPERTIES:
- Provides freeze/thaw resilience
- Increases flexural bond durability
- Offers protection against permeability
- Ensures more consistent coloration
- Achieves higher MPA (Megapascals) values
COMPLIANCE:
The admixture has been found to comply with the following parameters:
- Durability - (AS 3700, Appendix E)
- Bleed Test - (AS 1012.6)
- Flexural Strength by Bond Wrench - (AS 3700, Appendix D6)
- Compressive Strength - (AS 1012.8.3, 9)
Gibco MRF Lime Alternative meets Australian Standards regarding Bleed test, Compressive Strength, Flexural Strength, and Durability (M2, M3, M4 Mortar) when used as directed.
DIRECTIONS FOR USE: 40ml per 20kg of cement
