Comparison with Portland Cement
• Higher compressive strength • Greater flexural strength • Better crack resistance • Resists high heat much better • Lower cost at large scale operations
(a) (b)
Potential Product Applications
• Blocks, pavers, tiles, other small modular units • Walls, slabs, roofs, and columns • Structural panels, thin shells, and backer sheets • Pipe, culverts, vaults and other precast products
Ferrock’s Green Qualities
• Recycles steel dust as its iron source • Recycles fly ash as its silica source • Captures CO2 during hardening • Releases hydrogen as by-product
Methods of CO2 Capture
• Pre-cast products in a gas-filled autoclave • Pumping through embedded perforated pipes • Injecting under pressure into a wet mix • Mixing in saturated CO2 adsorbent
