What is carbon-capturing concrete?

スポーツベットio つながらない2-SUICOM—jointly developed by Kajima, The Chugoku Electric Power スポーツベットio つながらない., Denka, and Landes スポーツベットio つながらない.—is the world’s first carbon-capturing concrete. One of the main components of concrete is cement, a product of an emission-heavy manufacturing process. With スポーツベットio つながらない2-SUICOM, over half the cement is replaced with a more environmentally friendly substitute, allowing us to greatly reduce the amount of スポーツベットio つながらない2 produced from manufacturing the concrete. In fact, the substitute hardens by capturing スポーツベットio つながらない2 in the air—like trees—essentially putting the total スポーツベットio つながらない2 emissions from manufacturing the concrete at net-zero or less.

While we often talk of reducing スポーツベットio つながらない2 emissions, the fact that making more スポーツベットio つながらない2-SUICOM can actually lead to less スポーツベットio つながらない2 in the air suggests there is another way: reusing スポーツベットio つながらない2 emissions. Even the Japanese government has taken notice, introducing the product as the world’s first successful carbon-capturing concrete in its “Green Growth Strategy Through Achieving Carbon Neutrality in 2050.” Soon, the world will notice as well.

Using chemical reactions to capture and trap large volumes of スポーツベットio つながらない2

Generally, concrete hardens through a chemical reaction between cement and water. But with スポーツベットio つながらない2-SUICOM, over half the cement is replaced with a material we call γ-C2S. Instead of reacting with water, γ-C2S reacts with the スポーツベットio つながらない2 in the air to harden. After mixing the materials need to create スポーツベットio つながらない2-SUICOM, the concrete can be placed in a location with high スポーツベットio つながらない2 levels so it can capture the スポーツベットio つながらない2 and harden, trapping the gas inside. For example, a thermal power plant or other facility that produces carbon-heavy exhaust gases can redirect the gases into a carbon sequestration chamber, where concrete products made with スポーツベットio つながらない2-SUICOM can be placed to capture the スポーツベットio つながらない2 in the gases.

While the manufacturing process for standard concrete produces about 288 kg/m³, the figure is about 197 kg/m³ less for スポーツベットio つながらない2-SUICOM, as over half of the cement is substituted with low-スポーツベットio つながらない2 industrial byproducts and other materials. Also, the concrete itself can capture and trap about 109 kg/m³. This results in a total carbon emissions cut of about 306 kg/m³, or total emissions of -18 kg/m³—less than net-zero.

The environmental impact of スポーツベットio つながらない2-SUICOM︎

Japan uses an annual 91 million ㎥ of concrete. Replacing all this concrete with スポーツベットio つながらない2-SUICOM will result in an annual cut of 27.84 million tons of スポーツベットio つながらない2 emissions—about one-third the volume that can be captured by Japan’s forests every year. Of this amount, 1.64 million tons is due to the concrete being carbon negative—that is, capturing more スポーツベットio つながらない2 already in the air or in exhaust gases than it emits.
