A METHOD FOR PRODUCING AN ACTIVATED NESQUEHONITE

摘要

A method for producing an activated nesquehonite includes activating one or more nesquehonites by heating. The one or more nesquehonites may be formed by the reaction of carbon dioxide with aqueous magnesium ions at elevated pH, and may include barringtonite, nesquehonite, dypingite, hydromagnesite, and/or artinite and/or lansfordite. The activated nesquehonite may be useful in a building material, and have advantageous cementitious properties.
