C02-cured concrete passes tests

Published by
World Cement,


Purdue University and Solidia Technologies have conducted tests to demonstrate that concrete cured with carbon dioxide (CO2) performs comparably or better than traditional Portland Cement-based concrete. The tests covered performance related to cold weather resistance and exposure to extreme conditions.

Purdue University Professor of Civil Engineering Jan Olek commented: "On multiple indicators, our findings underscore comparable or favourable performance of the calcium silicate-based carbonated concrete under severe conditions."

Tests of the CO2-cured concrete show the product has good freeze-thaw resistance and scaling resistance in comparison with the traditional form.

The CO2-curing technology reduces water consumption in the production of concrete up to 80%, carbon emissions up to 70%, and the curing time to one day.
