Bioinspired Concrete
New bioinspired cement can be used to form artificial limestone aggregate for concrete, as well as cement for the binding phase of concrete. Amorphous calcium carbonate precursors were first used in combination with unstable calcium phosphates to form high strength, rapid setting carbonated calcium phosphate cements, similar to the mineral phase of bone. Later, these amorphous calcium carbonate precursors and other unstable polymorphs of calcium carbonate were used in combination to form calcium carbonate cements with high strength and other advantageous properties. In the last decade, mechanisms to use the carbon dioxide from the combustion of fossil fuels were developed, allowing very large quantities of calcium carbonate cementing precursor materials to be formed, making it a foreseeable reality that new concrete mixes comprising calcium carbonate, both as the aggregate component and the cementing phase of concrete can be establish broadly on a worldwide basis. Calcium carbonate concrete compositions enable a sustainable pathway for concrete as a construction material.
