摘要： A method of producing a carbonated composite material includes: providing a carbonatable cementitious material in particulate form; mixing the carbonatable cementitious material with water to produce a mix; forming a predetermined shape with the mix, wherein the predetermined shape has an initial pore structure containing an initial pore solution having a first pH; pre-conditioning the predetermined shape to remove a predetermined amount of the water from the predetermined shape to produce a pre-conditioned shape; carbonating the pre-conditioned shape in an environment comprising carbon dioxide to produce a modified pore structure containing a modified pore solution having and a second pH, wherein the difference between the first pH and the second pH is represented by a ΔpH, and the ΔpH is 1.0 or less.

摘要： A method of making a carbonated supplementary cementitious material is described that includes: selecting a raw material; reacting the raw material to form a synthetic formulation that can undergo a carbonation reaction; reacting the synthetic formulation with CO2 in the presence of water to form a carbonated supplemental cementitious material comprising calcium silicate and amorphous silica; subjecting the supplemental cementitious material to one or more of deagglomeration and grinding to produce a particle size distribution having a d10 of 1-5 μm and a d50 of 8-15 μm.

摘要： A method of making a supplementary cementitious material is described that includes: forming a slurry comprising water and a carbonatable material powder, wherein a weight ratio of water to the carbonatable material powder is at least 1; and flowing a gas comprising carbon dioxide into the slurry for 0.5 to 24 hours while maintaining the slurry at a temperature of 1° C. to 99° C. to form a carbonated slurry comprising CaCO3 and amorphous silica. A method of forming cement or concrete using the supplemental cementitious material is also described.
