The invention provides methods and compositions that prevent, mitigate or delay the onset of corrosion of iron or steel (e.g., plain carbon steel) components used as reinforcement or otherwise at least partially embedded in carbonated concrete composite materials and objects based on carbonatable calcium silicate cement.

Mitigation of corrosion in carbonated concrete based on low-calcium silicate cement

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 &#x394;pH, and the &#x394;pH is 1.0 or less.

Methods of forming cured composite materials with optimized pH and related compositions and systems

Apparatus and methods for improving the curing process of materials that cure under reaction with COand that do not cure in the presence of water alone are described, and examples are given.

Advanced curing equipment and methods of using same

The invention provides novel railroad ties manufactured from novel composite materials that possess excellent physical and performance characteristics matching or exceeding existing concrete RRTs. The RRTs of the invention can be readily produced from widely available, low cost raw materials by a process suitable for large-scale production with improved energy consumption and more desirable carbon footprint and minimal environmental impact.
