Creating CO2-cured (carbon dioxide) concrete could reduce carbon emissions into the atmosphere. One company has a new technology system and program that will lower energy consumption and reduce emissions when it comes to developing concrete.

U.S. Dept. of Energy’s NETL (National Energy Technology Laboratory), www.netl.doe.gov, Washington, D.C., contributes an additional $752,000 for Solidia Technologies’, www.solidiatech.com, Piscataway, N.J., research and development into using CO2-cured concrete in building and infrastructure products.

The project named “Utilization of CO2 in High Performance Building and Infrastructure Products” is cofunded by Solidia Technologies and NETL via its Carbon Storage Technology program. The objective is to use an alternative to OPC (ordinary Portland cement) to produce a CO2-cure concrete. The alternative cement, titled Solidia Cement, can lower energy consumption and reduce CO2 emissions. The concrete, named Solidia Concrete, delivers improved mechanical properties and durability while enabling for the safe and effective storage of CO2 in construction materials.

The project emphasizes the development and optimization of Solidia’s proprietary CO2-curing process. Currently, the technology has transformed to where Solidia Concrete can be developed using materials and equipment common to OPC-based concrete production.

New research goals are designed to help further the technology toward commercialization. The goals include demonstration of basic performance, demonstration of the use of this cement in at least six different precast concrete applications, and the commercialization of concrete manufacturing using CO2 curing.

NETL chose Solidia Concrete technology because of its potential to consume CO2 as it cures, which could reduce greenhouse gases emitted to the atmosphere.
