Abstract

The present invention relates to a method for producing a carbonatable binder composition comprising a mixed Ca-Mg silicate, comprising heating a reactive mixture to a temperature between 800 °C and 1400 °C. The reactive mixture comprises between 40 and 90 % by weight of a mineral source material comprising a Mg-comprising silicate, and between 60 and 10 % by weight of a Ca-comprising compound, wherein the percentage by weight of each component of the reactive mixture is based on the total weight of the reactive mixture, wherein the molar ratio of elemental Mg to elemental Si in the mineral source material is between 5:1 and 1:5, wherein the Ca-comprising compound is capable of reacting with the Mg-comprising silicate, and wherein the mineral source material comprises equal to or lower than 10 % by weight of Al, based on the total weight of the mineral source material, wherein the amount of AI is expressed as AI oxide in the mineral source material. The invention further relates to a carbonatable binder composition comprising at least 15 % by weight of akermanite.
