Product overview
Performance and application overview.
The China Marina Mystery
When 12 high-rises showed rebar corrosion after just 5 years, engineers were baffled – until they cut open a column treated with H-501:
"It's like giving rebar an invisibility cloak against chlorides."
How the Magic Works
1.Smart Film Formation
H-501's ions migrate to rebar surfaces, patching micro-cracks with γ-Fe₂O₃ crystals – think of it as self-healing armor for steel.
2.Chloride Jailing
The film's lattice structure acts like a nano-sieve:
3.Allows O₂ and H₂O passage (for cathodic protection)
4.Blocks Cl⁻ ions (size exclusion effect)
5.Concrete's Secret Weapon
Unlike competitors that weaken mixes, H-501 actually boosts 28-day strength by 9% – probably because it reduces micro-cracking during curing.
