The latter condition simulates the effect of earth pressure balance (EPB)-tunnel boring machine (TBM) on aggregates during the excavation and their successive reuse for concrete production.

Article. How recycling concrete could accelerate sustainable construction. In the built environment to date, it has been cheaper and easier to knock things down and start again, despite the cost in CO 2 emissions. We explore the potential to reuse concrete, and the benefits from saving CO 2, to greater stability. Andy Gardner.

· Concrete recycling is the process of breaking down old concrete and repurposing it for other uses. It’s an environmentally friendly way to reuse material that would otherwise end up in a landfill or be incinerated. Concrete recycling involves crushing, sorting, and cleaning the debris before using it as aggregate for new construction projects.

Another issue is that the production of cement from primary materials (limestone) is responsible for about 10% of the world’s CO 2 emissions. High-grade recycling of EOL concrete liberates the old cement paste from the concrete which can then be recycled into new cement with lower CO 2 emissions. End-of-Life concrete with steel rebars.

· Due to the carbon intensity associated with new concrete, it is almost always preferable to reuse concrete in its solid state – even in a lower quality application – than it is to crush it. Reusing concrete is always better if it displaces new concrete, as it also avoids carbon emissions. Stay circular, not spiral!
