无定形二氧化硅和水合碳酸镁（三水镁石，MgCO3·3H2O）是通过橄榄石（（Mg，Fe）2·SiO4）的酸溶解生产的。无定形二氧化硅是一种可行的补充胶凝材料，通过碳化形成三水菱镁矿，导致负碳过程。使用无定形二氧化硅作为辅助胶凝材料生产低碳水泥。全球橄榄石储量使其成为生产低碳混凝土的可行途径。
Amorphous silica and hydrated magnesium carbonate (nesquehonite, MgCO3·3H2O) have been produced by acid dissolution of olivine ((Mg,Fe)2·SiO4). The amorphous silica is a viable supplementary cementitious material, and the formation of nesquehonite by carbonation, results in a carbon negative process. Using the amorphous silica as a supplementary cementitious material produces low-carbon cement. The global reserve of olivine makes this a viable route to producing low-carbon concrete.
