Abstract
Cementitious compositions and methods for producing the cementitious compositions are described herein. The methods can include mixing a compound of the general formula MSiXO, MSiXO(OH), MSiX(OH), or MSiX(OH).(HO), wherein M comprises a metal that can react with carbon dioxide in a carbonation reaction to form a carbonate, Si forms an oxide during the carbonation reaction, X is an element other than M or Si, a, b, d, e, and f are greater than zero, and c is zero or greater, with a rapid setting hydraulic cement to produce a cementitious mixture. The methods can further include hydrating the cementitious mixture and carbonating the cementitious mixture. Carbonating the cementitious mixture can occur simultaneously with hydrating the cementitious mixture or subsequent to hydrating the cementitious mixture. In some embodiments, the non-hydraulic cement can comprise wollastonite. The hydraulic cement can be in an amount of from 5 wt % to 80 wt % of the cementitious composition.
