Ferrock is a sustainable construction material made from waste steel dust and recycled glass silica. When it reacts with CO₂ during curing, it forms iron carbonate binding carbon and making the material carbon-negative. It is stronger and more flexible than conventional concrete.
Suitable Climates: Performs well in a variety of environments.
Extreme Temperatures: Resists cracking in heat and maintains strength in cold due to low water absorption.
Marine/Coastal Areas: Highly resistant to saltwater corrosion, ideal for piers, seawalls, and waterfront structures.
Seismic Zones: Greater strength and flexibility make it better suited than concrete for earthquake-prone areas.
Polluted/Industrial Areas: Absorbs CO₂ during curing, contributing to emissions reduction.
Benefits: Stronger and more flexible than concrete, carbon-negative, saltwater-resistant, and made almost entirely from recycled waste making it highly sustainable.
Drawbacks: Limited supply of raw materials, unproven long-term durability, and restricted applications in large-scale construction.
Applications: Used in walls, roofs, facades, and ornamental or non-structural elements such as pavings, walkways, breakwaters, and slabs.
