- Remal Ashchem -F… Industrial Fly Ash.
- Remal Silikachem… High quality Industrial Microsilica.
- Remal Slagchem… High quality Industrial GGBFS.
The Benefits of Using
Volcanic Ash
Volcanic Ash
Concrete in its hardened state — with fly ash — shows improved performance with:
Greater Strength
Fly ash increases in strength over time, continuing to combine with free lime.
Decreased Permeability
Increased density and long-term pozzolanic action ties up free lime, reducing bleed channels.
Increased Durability
Lower permeability improves resistance to sulfate, mild acid and soft water.
Reduced Alkali-Silica Reactivity
Fly ash combines with alkalis from cement preventing destructive expansion.
Reduced Heat of Hydration
The pozzolanic reaction generates less heat, reducing thermal cracking.
Reduced Efflorescence
Fly ash binds free lime and salts that can create efflorescence.
Increased Workability
Concrete is easier to place and responds better to vibration.
Ease of Pumping
Pumping requires less energy and allows longer pumping distances.
Improved Finishing
Sharper architectural definition becomes easier with better surface integrity.
Reduced Bleeding
Fewer bleed channels decrease porosity and chemical attack.
Reduced Segregation
Improved cohesiveness reduces segregation that can lead to rock pockets.
Reduced Slump Loss
Concrete remains workable longer, especially in hot weather.
