Roam if you want to and dance this mess around with 52 girls.

No rebar; they used volcanic ash. We can use fly ash.

Interesting wiki article!

How do you know they were cold joints? Didn’t sound like that to me.

Going by the results, even with this so called ‘cold joint’ process the end result was stronger.

"Going by the results"

Did they do a compression test?

A cold joint is concrete poured/placed to that already there, even if not cured at any stage.

Another way for a few of the very rich to try to own all concrete pouring jobs. Those robotic pumps are going to have some shock and awe price tags on them.

Always tried to get my daughter’s band director to play Rock Lobster - would have been a great marching band tune (BTW that’s one of the ways you know you’re getting old - when the marching band is playing music you liked as a kid for the halftime show).

the girls are easy on the eyes even if Red does play for the other side

[Chode]

sure, why not

My understanding is that Rebar makes concrete more resilient and tougher, while limiting its lifespan.

Duct tape. Fixes everything. :)
