Estimating the term…
Provided herein are compositions and methods including hydraulic cement, supplementary cementitious material, and/or self-cementing material. Methods for making the compositions and using the compositions are provided.
A composition, comprising a non-naturally occurring supplementary cementitious material (SCM), the SCM comprising at least 47% w/w vaterite, wherein the composition upon combination with water, setting, and hardening, has a compressive strength of at least 14 MPa and wherein the composition comprises a carbon isotopic fractionation value (δ13C) of between −12‰ to −25‰.
A composition, comprising a non-naturally occurring SCM, the SCM comprising at least 10% w/w vaterite and at least 1% w/w amorphous calcium carbonate (ACC), wherein the composition upon combination with water, setting, and hardening has a compressive strength of at least 14 MPa and wherein the composition comprises a carbon isotopic fractionation value (δ13C) of between −12‰ to −25‰.
