I have a question on environmental science. The question is as follows:

Cement or concrete requires water for setting. And abandoned/garbage concrete remains as solid rocky material. So, is this phenomenon of cement setting cause a net reduction of water from Earth's pool of water?

I cannot yet find a site for environmental science. Where should I put this question i.e. what is the most appropriate Stack Exchange site for it.

  • So there is no portal of SE for environmental science?

  • I think Earth science may be a good fit since it looks for Earth's total water pool.

    Physics might also be helpfull, as this question is basicly about the process of the setting of concrete. Or the engineering site/departement could help out. They might have a clue on how much water it takes to make concrete, and how much water needs to evaporate for it to set.

    chemistry may help too on degradation of concreted cement

We have a Sustainable Living site

Sustainable Living covers

Sustainable Living Stack Exchange is for folks dedicated to a lifestyle that can be maintained indefinitely without depleting available resources.

It has a tag for

Questions regarding sustainable use of water, or water's impact on sustainability in general. For questions on [waste-water], [greywater], [seawater], [water-footprint] or [virtual-water] please use that tag.

It also has other potentially relevant tags for abandoned/garbage things such as a tag.

any addition of harmful substances or products in the environment (air, water, soil or food). For questions specifically about [air-polution], [greenhouse-gas-emissions] or [toxic-chemicals] please use those tags.

But do check out its help centre to find out more.
