The technology utilizes a cell to capture and manage the CO2 hence defining CapCell®. We generate a polymeric bubble that “Locks” in the CO2. This prevents it from reacting with the free water when concrete is first mixed.
For sure with concrete, timing is everything and since CapCell® locks up the CO2 at the mixing stage, the CO2 becomes beneficial to the concrete because it is released at the right time. CapCell® releases the CO2 to react with the calcium hydroxide once there is no more free water to react with the CO2. At this moment of CO2 interacting with calcium hydroxide, calcium carbonate is formed.This chemical reaction, once completed, is irreversible; meaning the CO2 is never again available as CO2 as it is now part of the concrete composite as calcium carbonate.
The above illustration of some common building materials indicates on a per pound basis, that concrete has a very low carbon footprint.
The use of concrete in the world today puts it as the largest consumed building material in the world and the second most consumed product next to water. The consumption and placement of concrete today is over 3 tons per person per year. This volume does however contribute 5-7% of the total CO2 emissions on a global basis.
A conclusion from the above information is that while concrete is a large contributor to the Greenhouse gas emissions, using almost any other product would generate an even greater carbon footprint.
Based upon the relative volume of concrete, CapCell® has the potential for the greatest reduction of CO2 in our environment, as compared to any other CO2 removal or reduction technology available.
