| 主权项 | 1. A cementitious composition, comprising: between 10-55 wt % of a composition comprising calcium carbonate, wherein between 50-100 wt % of the calcium carbonate is in a metastable polymorphic form comprising vaterite, and wherein the calcium carbonate has a δ13C value of between −12 to −30‰; and between 45-90 wt % of aggregate, wherein the cementitious composition after combination with water sets and hardens into cement wherein the calcium carbonate binds to the aggregate. | ||
