Solidia Technologies® has obtained a patent for the structure of CO2-cured Solidia Concrete™ from the U.S. Patent and Trademark Office which can advance the performance and sustainability of materials available to the global construction and materials industries. Solidia Technologies® holds the exclusive licensing rights to the patent, which is held by Rutgers University, where the original generation of the material was invented.
Solidia’s patented technologies have the potential to reduce the carbon footprint of concrete products by up to 70 percent. Requiring only modest changes to the processes currently used to make cement and concrete, Solidia’s process, which is more energy- and resource-efficient, makes solids out of packed powders without using a high-temperature kiln or furnace. The process produces innovative materials that offer greater strength and durability. This technology uses bonding elements based on silica and calcium carbonate which can create a wide range of attractive properties, including mechanical strength, resistance to freeze-thaw deterioration, and resistance to sulfate attack.
Though the initial technology focus was on unreinforced precast applications, including pavers and blocks, Solidia is now developing processes for reinforced applications, including aerated concrete, railroad ties, architectural panels and hollow core extrusions.
