Concrete is one of the most widely used materials in the world, but its production is a major source of greenhouse gas emissions. In fact, the cement industry is responsible for about 8% of global CO2 emissions.
Researchers at MIT have developed a new method for making concrete that is more sustainable. The new method uses sodium bicarbonate, also known as baking soda, to reduce the amount of CO2 emitted during production.
The researchers found that adding baking soda to the concrete mix helps to speed up the curing process, which reduces the amount of time that the cement needs to be heated. This results in a significant reduction in CO2 emissions.
The new method has been tested in the lab and has been shown to be effective in reducing CO2 emissions. The researchers are now working to scale up the process so that it can be used commercially.
If the new method is successful, it could have a major impact on the sustainability of the concrete industry. By reducing CO2 emissions, the new method could help to mitigate climate change and create a more sustainable future.
In addition to the environmental benefits, the new method also has the potential to improve the performance of concrete. The researchers found that the baking soda-treated concrete was stronger and more durable than traditional concrete. This could lead to longer-lasting structures and a reduction in the need for repairs.
The new method is still in the early stages of development, but it has the potential to revolutionize the concrete industry. If it is successful, it could help to make concrete a more sustainable and environmentally friendly material.
