FORTERA RECARB™ PROCESS

The Fortera Recarb™ process re-carbonates Calcium Oxide without losing its cementitious properties.  The result is a cementitious mineral that is rich in CO₂.

FORTERA REACTIVE CALCIUM CARBONATE

Fortera cement is similar in its makeup to ground calcium carbonate and precipitated calcium carbonate, but unique in its ability to add to cement’s performance with its cementitious chemistry. 

GCC

Ground CaCO₃

  • Inert Filler
  • No Binding Ability
  • Inconsistent Size and Shape
  • Fractured Limestone
PCC

Precipitated CaCO₃

  • Inert Filler
  • No Binding Ability
  • Customizable Size and Shape
  • Precipitated from Solution
Fortera RCC

Reactive CaCO₃

  • Reactive Mineral
  • Water Activated Binding
  • Spherical Particles
  • Precipitated from Solution

The calcium carbonate reacts with water transforming from spherical particles to a complex structural network of rods. This transformation is where Fortera cement gets its hardening and binding ability.

Cement is the second most consumed product on Earth behind water

Big innovations in this space allow for a big impact in the fight against climate change.
