Abstract
Methods of preparing a cementitious structure for carbon dioxide (CO) sequestration are provided. The cementitious structure may be a cast in a mold. First, a cementitious composite material comprising binder and water is conditioned, for example, in a mold by exposing the cementitious composite material to ≥about 50% to ≤about 80% relative humidity for ≥about 3 hours to ≤about 24 hours. The cementitious composite material is then dried to remove ≥about 10% by weight of initial water in the cementitious composite material. The cementitious structure formed is capable of a carbon dioxide uptake level of greater than or equal to about 6% by weight binder. The cementitious structure has a tensile strain capacity of ≥about 1% and a uniaxial tensile strength of ≥about 1 MPa. The method may also include carbonating the cementitious structure, following by an optional further hydration process.
