Nitrogen Dioxide Sequestration Using Demolished Concrete and Its Potential Application in Transportation Infrastructure Development

Achieving environmental sustainability of the United States (US) transportation infrastructure via more environmentally sound construction is not a trivial task. This proposal, which addresses this critical area (Focus Area 3), is aiming at transforming concrete, the material of choice for many transportation projects, into less environmentally harmful and better performing component of the US infrastructure. This will be extremely relevant to construction of pavements, bridges, tunnels, airports, marine installations and other transportation projects. Simultaneously, the project will address one of the most pressing public health issues, such as NO₂ emissions from cement kilns, by developing new applications of crushed concrete aggregates (CCA), which are already contributing to resource conservation and elimination of solid waste disposal issues. NO₂ emissions can cause various environmental and health problems. They contribute to the formation of acid rain, atmospheric particles, and various other toxic substances resulting in health problems, visibility reduction, eutrification and global warming. One of the most prevalent problems with NO₂ emissions is the formation of ground level ozone, which is produced by NOₓ (NO+NO₂) reacting with volatile organic compounds (VOCs) and CO in the presences of sunlight. Ground level ozone can damage lung tissue and reduce lung function. It is a significant problem nationwide as millions of Americans live in areas that do not meet the health standards for ozone. Among many sources of NOₓ emissions cement kilns are very significant contributors. They emit over 219,000 tons/year of NOₓ, which amounts to approximately 20% of all industrial emissions. High temperatures reached in cement kilns are favorable for NOₓ emissions and cannot be avoided.
