Mining environments destroy concrete. Here's how we're fighting back.
Acid attack, hypersaline water, sulphates, extreme heat — mining infrastructure faces conditions that can reduce 50 MPa concrete to rubble in just 2 years.
The Challenge
Mining operations expose concrete to aggressive environments that standard construction can't handle:
Sulphuric acid: Breaks down concrete microstructure, creating erosion and gouges
Hypersaline groundwater: High salt content corrodes steel while sulphates leach alkalis
Ammonium sulphate: Creates expanding forces and turns concrete to 'mush'
Extreme heat: 35°C+ pours increase cracking risk and reduce durability
Project Results
Glencore Murrin Murrin (WA) — Nickel & Cobalt Processing:
Previous service life: ~2 years before replacement needed
With hydrogel treatment: 6+ years and ongoing
Crack damage limited to 0.1-0.2mm — concrete integrity maintained
Carapateena Mine (SA) — Hypersaline Environment:
Hypersaline groundwater causing rapid deterioration
Hydrogel admixture binds calcium hydroxide — unavailable for leaching
Service life significantly extended, project ongoing
Also delivered: Mt Ida Lithium, Albemarle Kemerton, BHP Kalgoorlie, Kambalda Nickel Smelter
The Solution
Colloidal Nano Silica Hydrogel technology addresses the root cause — moisture carrying aggressive chemicals. Applied as admixture for new pours or spray-applied to existing concrete:
Blocks moisture transmission through the concrete matrix
Binds free alkalis so they can't be leached out
Improves workability in high-heat pours
Zero VOC — safe for operators and environment
Reduce replacement cycles. Extend service life. Protect your investment.
