CO2-cured concrete outperforms Portland cement

Tests conducted by engineers at Purdue University and Solidia Technologies show that concrete cured with carbon dioxide (CO2) performs comparably or better than traditional Portland Cement-based concrete for resistance to cold weather and exposure to extreme conditions.

“On multiple indicators, our findings underscore comparable or favorable performance of the calcium silicate-based carbonated concrete under severe conditions,” said Purdue University Professor of Civil Engineering Jan Olek.

Included in a white paper released yesterday, results of tests of the most damaging effect to concrete, freezing and thawing with two types of CO2-cured concrete show the product has good freeze-thaw resistance and scaling resistance.

Starting with a sustainable cement, the CO2-curing technology reduces water consumption in the production of concrete up to 80 percent, carbon emissions up to 70 percent, and the curing time to one day.

Entitled Performance of Calcium Silicate based Carbonated Concretes vs. Hydrated Concretes under Freeze-thaw Environments, the paper’s authors include Purdue graduate student HyunGu Jeong and Solidia Technologies Senior Research Scientist Jitendra Jain, Ph.D., Director of Research and Development Vahit Atakan, Ph.D, and Chief Technology Officer Nicholas DeCristofaro, Ph.D.
