Federal Hill Arch crumbling down

… when or if it goes.

Haven’t we, as a human civilization, been doing concrete for a while now? Why haven’t we gotten this down? Why is the train station crumbling for this reason too?

I just had a guy come to look at some crumbling concrete in my driveway, and he said the person who did it for the previous owner “didn’t do this concrete right.” Huh?

Can someone enlighten me as to the complexities of concrete?

Don’t use aggregate in the concrete that contains salt. Concrete can last longer if it’s protected from wetness, especially from acid rain or chemicals used to keep streets clear of ice.

I heard a totally unsubstantiated rumor that the RIRRC grinds up most of the plastic and ‘sells’ it to the landfill to use as a ‘cap’ for the daily waste. That way they can say that they ‘recycled’ and that they ‘sold the recyclables at a profit’.

I’d like to see what I saw in Oakland, CA but a step further:

City-provided trash/compost/recyclable barrels are the -only- barrels that will be picked up. The twist would be that you would pay a lot more for a ‘full size’ trash barrel, the standard-issue would be quite small. Barrels would have to be issued with your address branded onto them to prevent theft.
