DESCRIPTION:
GIbco's M.R.F is a chloride free performance admixture for masonry. It replaces traditional lime with an easy to use formula. Gibco's MRF is designed to enhance ordinary cement, turning it into high-quality mortars suitable for masonry applications. Laboratory tests comparing MRF with cement-lime mortars have shown it surpasses 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 plasticising properties of Gibco's MRF make it a viable substitute for lime, clay, and other plasticizers, leading to significant cost reductions, as 5 liters of it can replace up to 45 bags (900KG) of lime. Regardless of whether you're dealing with block, brick, or stone, MRF is capable of accomplishing the entire task.
PLASTIC PROPERTIES:
- Prolongs board lifespan and setting duration
- Creates a uniform gel-like consistency
- Enhances ease of work
- Boosts adhesion capabilities
- Lessens the need for water
HARDENED PROPERTIES:
- Offers freeze/thaw resilience
- Strengthens flexural bond durability
- Provides protection against permeability
- Ensures more consistent coloration
- Delivers higher MPA (Megapascals) values
COMPLIANCE:
The admixture was found to be compliant 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 complies with Australian
Standards in terms of Bleed test, Compressive Strength, Flexual Strength and
Durability (M2, M3, M4 Mortar) when used as instructed.
DIRECTIONS OF USE: 40ml Per 20kg of cement
