Why Seven Rings Special?
- Higher long-term strength due to its pozzolanic reaction.
- Improved workability of the concrete and eases placing of compaction.
- Give better, smoother surface finish of structural members.
- Reduced water demand results in higher strength of concrete.
- Less possibility of bleeding and segregation due to its lower water requirement.
- Less heat of hydration results in lower thermal expansion and less possibility of cracking afterwards.
- Strong resistance to chemicals (sea water, acids, chloride, sulphate).
- Increase fineness reduces the permeability and results in denser and superior fair-faced concrete.
- Prevents corrosion of concrete & embedded steel.
- Reduces lime leaching.
- Potential to save chemical admixtures for Ready Mix Concrete (RMC).
