Concrete Cured with Carbon Dioxide Shows Favorable Performance Under Severe Conditions

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, Ph.D., P.E., who co-directs the ongoing research with Purdue Professor Jason Weiss, Ph.D.

Included in a white paper released today, results of freezing-thawing tests of performed on two types of CO₂-cured concrete show that the product has good freeze-thaw resistance and scaling resistance. Starting with 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.
